About EI Sensors

Temperature Sensors - Thermistor & RTD Probe Assemblies

EI Sensor is a prominent manufacturer and provider of temperature sensors. Products include PTC and NTC Thermistors, RTDs (Resistance Temperature Detectors), Thermistor Probe Assemblies and RTD Probe Assemblies


Thermistors are THERMally sensitive resISTORS whose electrical resistance changes when subjected to a corresponding change in body temperature. EI Sensor offers thermistors capable of operating over the temperature range of -70°C to +300° Celsius.

RTDs are temperature sensors that exhibit an increase in resistance when subjected to an increase in their body temperature. EI Sensor provides thin film platinum RTD sensors that are capable of operation from -200° to +850° Celsius.


Thermistors and RTDs are commonly mounted into protective enclosures. The resulting temperature probe assemblies are highly customized to fit specific applications and can be used in a variety of demanding temperature sensing applications. The protective enclosures can be formed out of stainless steel, aluminum, copper, brass and plastic. Extension lead wires such as Teflon, Kynar and PVC are commonly used and there are many different types of connectors which can be added for ease of installation.
