KELE Encapsulated Thermistor and RTD Sensor KTM*, KTMR* Series

KELE Encapsulated Thermistor and RTD Sensor

 

The Kele KTM, KTMR Series Thermistor and RTD encapsulated sensors provide remote temperature sensing for building automation systems and mechanical equipment room instrumentation. The active sensing element is a highly stable thermistor material or platinum RTD. The sensor is encapsulated with a low mass, high conductivity compound for good heat transfer characteristics. It is enclosed in a tough, miniature cylinder, 0.17" (0.43 cm) in diameter, which is small enough to be installed in most HVAC thermostat enclosures.
