Rail, Light Rail, Buses, Trucks & Support Equipment – Weschler Meters

/in , , ,
Commercial transportation is a target industry for Weschler products.  Diesel electric locomotives use analog meters and digital meters to monitor generator and motor condition, as well as the status of other on-board systems.  We manufacture special illuminated and ruggedized meters to display vehicle speed in the cab.
Buses and heavy duty trucks benefit from the ruggedness and reliability of Weschler indicators.  Our gauges provide accurate readout of vehicle speed, motor RPM, engine temperature, fuel level, hydraulic pressure and other parameters.  Many models can be interfaced to on-board data loggers and telemetry systems.
Emergency vehicles incorporate a combination of digital and analog meters – in fire engine pumper controls, ambulance monitor panel and other vehicle sub-systems.
Weschler products are used in the construction and maintenance of roadways and rail lines.  Asphalt paving machines track temperatures and feed rates with Weschler digital instrumentation.  Concrete batch plants monitor and control mixing operations with our analog & digital meters.   Meters and transducers are used to monitor motor currents on heavy off-road construction equipment.

camera functionCamera Systems provides a complete camera portfolio for industrial process monitoring and security surveillance for hazardous and industrial areas. Due to our innovative SNF*-technology, all cameras are considerably lighter than any existing ones, and extremely robust. Almost all of our cameras are designed for operation in extreme temperatures ranging from -40°C to +75°C, even our infrared camera with day/night vision.

We are therefore able to design complete surveillance systems for any type of production plant, be it an oil rig, a tank farm, onboard ship or in process plants in the pharmaceutical or chemical industries. For control and standard monitoring, we have the ISview software package.

Larger surveillance systems with up to several hundred cameras are covered by the professional SeeTec software.

Aerospace & Defense – R25 Heavy Duty Brushless Resolvers

/in , , ,

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.

Green Energy

Energy management and energy conservation start with the ability to monitor power and energy use.   For electrical systems, this involves measuring DC or AC power (Watts, VA, VAr) or energy (Wh, VAh, VArh).
In fixed installations, digital meters offer a range of display formats, capabilities & sizes. Single display power/energy meters start at $150.  Multiple display meters with user selectable parameters are available for $200-800, depending on configuration and capabilities. Bargraph power meters, which show a digital reading and analog level, start around $350.Advanced parameters, including power factor, demand & harmonics, are standard on many models. Most meters also offer options for setpoint alarms & network communications.  Specialized meters are available for applications such as generator monitoring or load shedding.  See the more popular digital:
