Therm-O-Disc NTC Thermistors offer economical, reliable and accurate solutions to those applications requiring more extensive sensing than the one or two temperature points typically offered by a bimetallic thermostat. 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.

Therm-O-Disc NTC Thermistor Features:

•Economical

•Long-term stability

•Accurate

•A wide variety of packaging options available

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.

Rugged Assembly

Rugged thermistor probe assemblies from Therm-O-Disc can be depended upon to meet tough application requirements. Select from a wide range of standard body designs already available, or work with experienced engineers to develop a special thermistor design to meet exact application requirements.

Features and Benefits

Therm-O-Disc thermistor probe benefits include:

•Engineered to specific application’s exact requirements

•Thermally responsive

•Increased performance of the overall system in terms of energy consumption and ease of use

•Reduced assembly cost and increased reliability

•Rugged performance and long-term stability

Therm-O-Disc plastic over-molded thermistor sensor features and benefits include:

•Plastic provides a much higher protection against moisture over time

•Plastic probes can be made into more application-specific shapes

•Plastic probes can eliminate multiple-part assemblies for customers and reduce their labor and combined material cost

•Lower weight content than metal probes can benefit transportation costs

•Piece price is typically lower than metal-based probes

Sensor Varieties

Therm-O-Disc designed thermistor probes use a variety of sensors to further enhance their use in applications. The most common sensor is the H-Series NTC thermistor which can be supplied with tight tolerances at multiple temperatures.
