CAREL Temperature Probes with NTC Thermistor
NTC - *HP*, *WP*, *WF*, *HF*, *HT* & *INF*
For their various controllers, CAREL propses a range of sensors with different features, suitable for different applications mainly in the HVAC/R sector.
The precision achieved by the technical solutions adopted in the development of the sensor, and the reliability resulting from the tests preformed, make the CAREL sensors reliable transducers for measuring temperature, at an affordable cost.
Piercing probes are also available, with or without preheating element, for measuring the core temperature of the product.
