Variohm EuroSensor has launched the new ENTC-MP-10k3977-01; a polyimide sleeved, high-tolerance NTC thermistor aimed at high-sensitivity medical instrumentation and industrial temperature measurement applications. More specifically, the sensor is designed for precision sensing of small mid-range temperature changes in non-condensing moisture environment temperature sensing tasks.
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 such as engine temperature controls, refrigeration, industrial instrumentation, and medical equipment.
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, 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 by an 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.
