Thermocouples There are many different types of thermocouples. They are made of different types of wire and have very different properties, making one type better for a specific application than another. Thermocouples can measure temperatures over wide ranges, fairly inexpensively. Read more...
RTD's An RTD (Resistence Temperature Detector) capitalizes on the fact that the electrical resistance of a material changes as its temperature changes. RTD's rely on the resistance change in a metal. Read more...

News at AST
Gas Measurement Temperature Solution - For most gas pipeline companies, flow computers are used to measure the volume of the gas flowing through the line. This allows them to properly charge their customers for product delivered. One of the required inputs needed for the flow computer to calculate volume is the temperature of the material.Read more...
Power Industry - Thermocouples and RTD's manufactured by Applied Sensor Technologies have been supporting the operations of the Power Industry for many years. If you look around, you might find us monitoring the temperature of your turbine exhaust, or controlling the heater on your precipitator hopper, or providing input to your natural gas flow computer, or monitoring the heat in your HRSG or boiler tubes.

In many applications, it is not feasible to wire a temperature sensor directly into the control system, due to distance or signal quality. Our temperature transmitter is 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 the many terminal head variations that we offer, our UNI5 transmitter line offers reliability and value.
