Resistance Temperature Detector
RTD sensors are used to measure temperature by changing resistance proportional to the temperature. RTD's are designed with basic temperature elements as well as fully packaged assemblies. These so called RTD probes consist of a RTD sensor element, a sheath or housing, an epoxy or filler, extension leads and sometimes a connector or termination. Various sensor materials are available based on customer requirements for material compatibility, accuracy, and measurement range. Standard packages as well as custom designs allow for the flexibility to design the most suitable RTD temperature sensors for a variety of applications.
RTD Sensor Applications
RTD temperature sensors and probes can be integrated into a variety of applications, spanning various industries. These temperature sensors can operate on board level components as well as in harsh and hazardous locations with various agency approvals. Our broad selection of temperature products meet the specific sensing demands of critical OEM applications, including medical, aerospace, automotive, instrumentation appliances, motor control and HVAC/R.
An RTD is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. Learn more about Resistance Temperature Detectors (RTD's).
