topban-aerospaceAerospace & Defense

When the military relies on a line of resolvers for proven performance, you know it’s a top-of-the-line product. Precise feedback and speed control of their aircraft at all times is imperative to pilots. That’s why they trust Harowe brand resolvers to deliver reliable and accurate feedback.
Thrust reversers, throttle valve indicators and starter/generator feedback are just some of the critical mechanical and jet operation applications that Harowe brand resolvers control. They are also used for flap position indicators, fuel control valve indicators, inertial guidance systems and auto-pilot controls. Battling gravity and top speeds, pilots must be confident their resolvers will perform to specification.
aboutus-adHarowe products are designed to meet aerospace and defense requirements, including: high-speed applications (over 30,000RPM), high-temperature environments (up to 200C), high-shock and vibration environments, dual speeds, and tandems for redundancy applications. We can supply COTS, Modified COTS and ITAR solutions.

New Digital Thermostats will Improve the Performance of Refrigeration and Heating Applications

West Control Solutions has launched the CAL Thermostats family, a range of easy-to-use temperature thermostats that improve performance and efficiency for food and beverage manufacturers. With a simple user interface, large clear display and a high ingress protection-rated casing, CAL Thermostats offer precision monitoring of temperatures within ovens, fryers, refrigerators and other chillers.

Digital Thermostats with NTC Sensor InputSelf-Tuning Digital Thermostat

The CAL ET2011 digital thermostat is an easily programmable standard thermostat for heating or cooling control, with a 4-digit display. A simple panel clamp enables quick installation and release, while a range of input options for thermocouples or PT100 provides capability to meet a wide range of application requirements. The automatic, ‘self-tuning’ calculation of PID parameters, soft-start functionality and the option for relay or SSR output to be assigned as the main control output all contribute to the flexibility and efficiency of the instrument.

Defrost Thermostats for Compressor Defrost or Fan Control

For refrigeration applications where defrost is required, the CAL EDT defrost thermostats offer different output options for compressor defrost or fan control, up to two NTC thermistor sensor inputs and an option for an external digital input to trigger a defrost event. The devices support different defrost cycles: compressor shutdown, electric or hot gas defrost cycles. Fast set-up is enabled using the “CAL key”, a flash memory key that allows configuration settings to be copied from a master device to any further devices that share the same configuration, saving time and ensuring commissioning or down time is minimised. An RS485 option is available for monitoring and reporting, while a real-time clock for initiating the defrost cycle at a specific time of day.
The CAL thermostat range provides an aesthetically-pleasing design featuring a large display that is ideal for both industrial and non-industrial applications.

Power Generation – Combustion Control

/in , , , , /by


OxyFire Sensors: Typically used in a coal-fired power boiler, the high temperature, in-situ oxygen sensor is generally installed in the boiler water-wall, above the nose arch and above each of the burner banks. This configuration allows the boiler operators to center the fireball in the radiant zone and “balance” the boiler.

Typically installed above the slag line, the sensors give the boiler operators a unique perspective on the combustion process, eliminating the typical “air infiltration” that confuses “low temperature” sensors located in the back pass.
Benefits from using Marathon Monitors’ Combustion Optimization System to “trim” the draft are:

  • Balanced boiler – Centering the fireball
  • Minimizing NOx formation
  • Reduces over-all maintenance costs
Providing the operators with this type of information allows them to do their job more efficiently, eliminates CO (carbon monoxide) pockets, and helps in achieving “lowest cost” megawatts.

Oxygen Sensors: Oxyfire High-Temperature Series

LOROX Low-Range Temperature Series
LOROX Sensors: Typically used in fossil fuel fired power boilers where the slag line is very high. These sensors are often installed in the back pass section where temperatures are too low for Oxyfire sensors to operate. Response time is still very fast and the LOROX is easily maintained without removal.
