Power

High quality and high reliability

Toxic gas detectors and pressure and temperature instrumentation manufactured by United Electric Controls (UE) and Applied Sensor Technologies have supported power industry operations for many years. You will find UE products monitoring the temperature of a turbine exhaust, controlling the heater on a precipitator hopper, providing input to a natural gas flow computer, or monitoring the heat in HRSG or boiler tubes.

Gas Detector

The Vanguard WirelessHART® gas detector reliably monitors toxic and combustible gases without time-consuming installation, production disruption, or high maintenance cost. It is the only solution that offers 5-year battery life. Plug-and-play installation, one-button calibration, and self-configuration make it the easiest wireless gas detector to operate and maintain in power industry applications.

Temperature Transmitters

Many times, it is not feasible to wire a temperature sensor directly into the control system due to distance or signal quality. UE temperature transmitters are an ideal choice to convert the sensor’s output signal to a reliable 4-20 mA or HART ® protocol. Designed to fit into one of our many terminal head variations, the UNI5 transmitter line offers reliability and value.

Thermocouples

From the bearings to the boiler, field-proven thermocouples and RTDs manufactured by Applied Sensor Technologies are designed for reliability and durability. These sensors are ideal for gas turbine exhaust, heat tracing systems, gas flow computers, and cooling water outflow. Our Lean Manufacturing and Lean Enterprise philosophies help create maximum value in everything we do.

Applications

• Boiler tube temperature
• HRSG efficiency
• Gas turbine exhaust
• Heat tracing monitoring
• Ash hopper heater control
• Bag house and precipitator monitoring
• Gas flow computer temperature input
• Cooling water monitoring
• Bearing temperature
• Stack emissions monitoring

Thermowells

UE provides a wide range of thermowell designs in many different materials and applications that range from natural gas supply lines to HRSG. These include threaded wells for water treatment equipment, flanged wells, plus socket-weld and weld-in styles in a variety of carbon steels, stainless steels, and high-nickel alloys. UE also supplies special protection tube designs for applications such as bag houses and precipitators — where fast response is required in an abrasive environments.

Applications

• Pipeline compressor stations
• Gas flow monitoring
• Metering runs
• Input to RTUs and SCADA systems
• Flare gas recovery

The Sensor Box™

A flexible, cost-effective program designed for power plant applications, the Sensor Box™ contains parts that allow the construction of a variety of assemblies. If a temperature sensor fails in the field, a replacement is readily available with the Sensor Box. It’s useful not only for emergency situations, but also during outages where timing is critical and requirements may not be known until the last minute.

Custom Solutions

Applied Sensor Technologies offers a wide variety of standard assemblies, but some needs are unique. Call us if you have a challenge or can’t find a standard product that fits your requirements. We can build the perfect sensor for you.
