The compact GIM500R inclination sensors in robust aluminum housing are ideal for use in harsh environments.
When it comes to tough outdoor use, many sensors reach their limits. Inclination sensors by sensor expert Baumer stand for maximum reliability and durability even in a harsh environment. Thanks to the extremely robust and resilient design, the new GIM500R sensors are ideal for outdoor applications in mobile automation and ensure maximum system uptime.
The GIM500R inclination sensors excel by ultra-high accuracy up to ±0.1˚ for absolute reliability and precise positioning. The E1-compliant and uncompromising design with optimal EMC properties, IP 69K protection and corrosion resistance up to C5-M is particularly addressing demanding outdoor applications. Their shock and vibration resistance up to 200 g respectively 20 g and the wide temperature range from +85 down to -40°C make the inclination sensors particularly durable in temperature fluctuations and any type of soiling. The integrated EN13849-compliant firmware meets the highest requirements on reliability which allows for standard components to be used in functional safety systems up to PLd level. Another hallmark of the new series is optional redundant system design where required.
Inclination sensors of the GIM500R series stand out by their compact aluminum housing, high cost-efficiency and maximum flexibility in system design. They fit in the confined installation space prevailing in mobile automation and heavy vehicles.

Sensor expert Baumer is further expanding their portfolio of cable transducers being the easiest, most reliable and cost-efficient way to measure linear motion within a path from 0.5 to 50 m. New series GCA5 is practice-proven when the going gets tough, for example at mobile machinery, and is ideally suited for use in cramped installation conditions.
The compact cable transducers of the GCA5 series do not compromise on maximum robustness in demanding applications. The housing of impact-resistant plastics, the corrosion-proof stainless steel cable with abrasion-resistant nylon sheath and the non-contact wear-free magnetic sensing make them the optimal choice for reliable and low-maintenance deployment in harsh environments. Thanks to the innovative design with three-chamber-principle, both electronics and stainless steel spring are hermetically encapsulated against the cable drum. The integrated flexible dirt skimmer at the cable inlet is an additional protection against humidity and ingress of any other harmful environmental substance for maximum application reliability.
The cable transducers of the GCA5 series feature a maximum measuring range of 4700 mm and are available either with integrated CANopen interface or analog output 0.5…4.5 VDC. The CANopen variant provides additionally redundant position sensing and hence simplifies function monitoring at control level. Housing protection IP 67 (cable inlet IP 54), shock resistant up to 50 g, vibration proof up to 10 g and the extended temperature range from -40 to +85 °C make the cable transducers particularly robust and resistant against temperature fluctuations and all kinds of soiling.
The cable transducers of the GCA5 series excel by their narrow design and shallow installation depth of a mere 65 mm which allows easy installation even in cramped space – as prevailing in mobile machinery and utility or transport vehicles. Cable transducers series have been standing the test of time in outrigger positioning at mobile cranes and telehandlers as well as height positioning at floor conveyor trucks and stacker cranes. Whether as OEM equipment or for retrofit – the robust and compact cable transducers are ideal for precise measurement of linear motion in demanding applications.

Embedded workflow, engineering model support, and auto-discoverable assets are among the technologies keeping SCADA alive.
Kevin Parker 12/07/2016
Placing computer power onto “edge devices” as near to production as possible is a goal hotly pursued in today’s industrial automation circles. What’s more, in just the past few years, copious amounts of process and operations data moved to the cloud.
Yet these developments by no means obviate the role of supervisory control and data acquisition (SCADA) systems as a convenient and secure aggregation point. SCADA instances are found across the oil and gas industries and in all major production industries. In fact, smart instrumentation and cloud modalities make SCADA more relevant to the entire business enterprise.
“One basic difference in today’s oil and gas environment is that it is expected that operations data can be accessed from the corporate office,” says Doug Rauenzahn, a product director.
A SCADA installation typically includes computer workstations, programmable logic controllers (PLCs), and other instrumentation for system inputs and outputs (I/O). Unlike a distributed control system (DCS), SCADA control functions may be limited. The feedback loop passes through the PLC, while SCADA monitors loop performance. That is, PLCs assume parameter control, while operators monitor results and, for example, change set points. Peer-to-peer communications among the controllers may be lacking.
The more modern programmable automation controller (PAC) addresses these concerns to compete with a DCS as a control paradigm.
Another element of a SCADA installation is a distributed database and tag- or point-data elements. Each tag represents a single system input or output value. Examined in series, these value-time stamp pairs track point history. Metadata may also be stored with tags. Systems with many thousands of tags are common today.
SCADA includes tools for process design and development. Of prime importance is the ability to efficiently implement multiple instances of a system. SCADA implementations often include pre-integrated data historians and portal connectivity to aggregate data and communicate results, analytics, etc., to interested parties.
To deal with the complexity of it all, modern SCADA uses object-oriented programming to define virtual representations of each particular entity mirrored in the graphical interface. These virtual objects included address mapping of the represented node and other valuable information. Virtual objects also play a role in supporting SCADA’s ease of implementation since they are available for reuse in multi-plant scenarios.
Object orientation opens a wealth of possibilities. “The object model created in SCADA is an abstraction that can be used by other systems aimed at analytics and optimizations and to feed first-principle engineering or other type models,” says Andy Weatherhead, manager of global engineering.
SCADA increasingly incorporates the Industrial Internet of Things (IIoT) technology. Smart instrumentation and cloud technologies lead to more complex control algorithms, while open network protocols improve SCADA cybersecurity.
Upstream SCADA territory
As previously mentioned, SCADA is used extensively in industries including energy and power, water and wastewater, manufacturing, and refining. In the oil and gas industries, sub-sea level drilling and production control are typically the purview of DCS, although SCADA implementations tend to proliferate as a means to roles, based on collaboration or cross-functional operations.
According to Darren Schultz, director, of SCADA, oil, gas, and chemicals, in today’s North American upstream gas markets, the gas, well, or pad is typically PLC-controlled, as are the gathering systems connecting the pads, including the compressors involved. On the other hand, gas processing facilities, transmission gas lines, and gas delivery typically are under an independent DCS, and SCADA is widely applied in pipeline and distribution networks.
“Oil production is similar in that field operations are most often addressed with SCADA, refining with DCS, and pipelines are again SCADA-equipped. In the oil industry, you also have tank farms, which may be managed using DCS from nearby processing plants,” says Schultz.
Actual control requirements differ by well type. For natural-flow wells, casing pressure, temperature, and flowing-valve position are monitored, while gas wells further rely on compensated flow calculations. Remote control is limited to the shutdown valve on a natural-flow well. For an artificial-lift well, motors or gas lift valves are also controlled.
Compressor stations in a pipeline system maintain pressure for gas delivery to destination. A gas pipeline typically has multiple compressor stations. A gas or liquid pipeline has block or segmenting valves that can shut down pipeline segments. Valued information includes pressure, temperature, flow, and valve position. Pump stations maintain system pressure or match flow demand. Multiple pump stations connect to the pipeline, with connectivity back to a central location.
Beyond supervision and control
“What’s exciting about the upstream today is the great uses it has for cloud computing and for something that is happening right now, the advent of auto-discoverable assets technology,” says Weatherhead.
Use of auto-discovery will significantly ease the pain of field implementations. “The cloud offers a ready-made infrastructure for SCADA,” says Weatherhead. “Combined with a services approach, an operator can have power, use a wizard to set up, and be processing data in 5 minutes. Unfortunately, today, in too many cases, you see sites where despite using the very latest drilling technologies, after 3 months of work, they still haven’t tied into SCADA. Three months of lost optimizations is real money.”
Another interesting element to SCADA to petroleum industry efforts aimed at best practices actually has been available for some time. “Over the last several years I’ve found intense interest in the subject of workflows in upstream oil and gas,” says Weatherhead.
Workflows are the traditional discipline of industrial engineers or operations management specialists, types not typically found at wellsites. But workflow isn’t something applied exclusively in offices and factories. A defined process and defined work flow are important benefits for an upstream sector with operations that employ multiple 3rd party-specialist suppliers.
“What [are] wanted are workflows for such things as ‘take a well test’,” says Weatherhead. “It sounds simple, but if you don’t have the different systems involved well-test integrated, you can’t create a relevant workflow. Again, an object data model as found in SCADA provides a level of abstraction that allows easy linkages, much as a bus where elements use device drivers to plug in.”
According to Technical Toolboxes, an industry software provider, when thinking about SCADA implementations, one way to segment upstream operations is pertaining to a) reservoir, b) completion, and c) production. Once the requirements of each are defined by means of production workflows, improvements can be made. Cross-functional objectives can be addressed as role-based goals for “reservoir surveillance, well-test validation, and production optimization.”
With a Web browser, all interested parties-and no malicious parties-access a reliable, single source of truth. It’s the availability of a relevant, configurable interface that can kick off an evolution in how things work.
What’s more, “Web-based interfaces provide a self-service environment so resources aren’t wasted laboriously building or modifying screens. Users quickly become adept at building them and the dashboards that serve their needs. That being said, hesitations persist about using Web interfaces in a control network, as opposed to a business network,” says Rauenzahn.
IT-based automation strategies for the oil and gas industry
Programming logic controller (PLC) panels come in almost every shape and size with some of them being freestanding and others being wall-mounted and choosing the right solution for a particular application can be difficult.

Controlling equipment has always been of interest in industrial applications. Before modern-day computers came into existence, a series of relays controlled that equipment and may have numbered into the thousands. Any updates required expensive and time-consuming manual labor by electricians who needed to rewire all of the relays.
The adoption of digital computers gave rise to the modern programmable logic controller (PLC): a digital computer utilized for the automation of various processes within an industrial facility. The PLC is designed for applications ranging from controlling parts of an assembly line to automating and controlling the light fixtures in an establishment.
There are similarities between a personal computer and a controller. Both a PLC and a personal computer have a CPU, memory, and input/output (I/O) units. On the other hand, a controller is built for industrial applications. It is designed to operate under harsh environments often seen in many facilities. In essence, the PLC and a PC gather and release information.
The PLC panel can be used in a wide range of industrial applications, primarily for automating processes and increasing control over critical systems. The processor controls electrical power and is commonly referred to as an automation panel. PLCs are utilized in many industries including:
Automotive industry: the automotive industry is one of the largest users of PLCs and one of the first industries to embrace factory automation fully. The industry still makes use of automation through PLC panels on an ongoing basis.
Marine: from controlling specific parts of the vessel to a full vessel system, it is an important part of maintaining operation where failures can cause severe consequences.
Power generation: PLC panels can be used for some processes within a power generation facility, such as automating the soot blower controls
Paper making: PLC panels can be used for controlling many processes within the paper mill industry.
Automation control: The applications that achieve automation through the use of PLCs include HVAC systems, car wash systems, material handling, and conveyor systems
