KTM/KTMR Thermistor & RTD Sensor
Brand: Kele
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.
Features- Wide selection of thermistor and RTD curves
- Adaptable miniature sensor
- High Heat Dissipation Constant
- Easy to mount with clips
- Pre-aged, highly stable thermistor material
