NTC Thermistor

Therm-O-Disc's NTC thermistor temperature sensors offer low cost, reliable performance, and high accuracy, providing clear advantages over traditional bimetallic thermostats that typically measure only one or two temperature points. These sensors feature highly sensitive thermistors whose resistance changes rapidly with temperature. When integrated with electronic circuitry, they enable continuous temperature monitoring over a wide range.

Product Features: 1. Low cost 2. Stable performance, long service life 3. High sensitivity 4. Various packaging options available. Principle of Operation: An NTC thermistor is a semiconductor ceramic made from various metal oxides, whose resistance decreases as temperature increases. Controlled by corresponding electronic circuits, it measures ambient temperature. Unlike bimetallic thermostats which provide both temperature sensing and circuit control, thermistors themselves do not control heating elements, relays, etc. They act solely as temperature sensors; the corresponding electronic control is handled by the connected circuitry.
