Product Specifications

Appliance/HVAC Probe Series

The 95JB NTC Thermistor Probes offer economical, reliable and accurate solutions to appliance and HVAC applications requiring more extensive sensing than the one or two temperature points typically offered by a bimetallic thermostat. The 95JB NTC thermistors provide a change in resistance with temperature that when combined with an electronic circuit provides a means of continously measuring temperature over a very wide range.

Applications

• Boiler Heating Systems
• Liquid Applications

Features & Benefits

• Fast Response Time
• Standardized Packaging

Operating Principle of NTC Thermistors

NTC thermistors are semiconductor ceramics made with various metal oxides. Their electrical resistance decreases with increasing temperature. This resistance is processed by an electronic circuit to provide temperature measurement. While a bimetallic thermostat provides both temperature sensing and electrical circuit control, the thermistor itself does not provide any control over heating elements, relays, etc. The thermistor is strictly a sensor and any electrical control would need to be implemented by the circuit utilzing the thermistor.
