Thermistors are mainly used as temperature sensors, inrush current limiters, self-resetting over-current protectors and self-regulating heating elements. The most common type of temperature sensor is a thermometer, which is used to measure temperature of solids, liquids and gases. It is shaped into a disc, a rod or a bead. Quartz sensors operate, without cooling, up to +750 °F (+399 °C) on compressors and pumps. Ultrasonic transducers for high temperature applications. The transducer measures the load on the engines. The biggest concern when … The transducer is always free from the load and temperature. More information on vision and imaging sensors may be found in our related guide All About Vision and Imaging Sensors. This temperature sensor is based on a standardized Pt100 or Pt1000 element, which gives a reliable and accurate measurement. Application of Temperature Transducer Temperature transducer is used to measure the temperature of the air In a Temperature Sensor, the changes in the Temperature correspond to change in its physical property like resistance or voltage. Application of Temperature Sensor. A Temperature Sensor, as the name suggests, senses the temperature i.e. Thermistor sensor applications often require a particular type of thermistor temperature sensor depending on whether you are seeking to measure, control, or compensate temperature. The four most common types of temperature sensors, ranging in responsiveness and accuracy from high to low are: A temperature transducer is an electrical device usually used in automated air-temperature control sequences. A temperature transmitters converts the thermocouple or RTD signal to a 4-20 mA output signal and is the ideal solution for many remote temperature measurement applications.
