Variohm EuroSensor expands NTC thermistor range with polyimide sleeved variant for medical applications

The new thermistor is based on the durable epoxy bead EB series encapsulated sensors. Its 1.27mm diameter by 5 mm long polyimide sleeve offers high-temperature stability, robust mechanical properties, and superior chemical resistance and is a widely used material in applications where durability is an important requirement. With a time constant of 15 seconds in still air, the thermistor’s resistance at +25°C equates to 10 kΩ whilst a 25/85 Beta value constant of 3977K ± with a 0.5% accuracy suits fine precision temperature measurement supported with interchangeability of ±0.1°C over a range of 0 to 70°C. An operating temperature range of -40°C to +90°C is specified. The ENTC-MP is supplied with insulated leads – approximately 150 mm long with 2 x 30 AWG solid copper wires with Kynar insulation. Custom versions can be supplied on request.

Variohm’s recently launched ENTC range covers high-sensitivity NTC thermistors in a choice of hermetically sealed glass or epoxy encapsulation. The range offers a flexible choice of operating temperature, precision, and time constant performance for applications from engine temperature controls to refrigeration, industrial instrumentation, and medical equipment.
