New NTC thermistor designed for medical equipment usage

Expanding its extensive range of temperature sensors, Variohm EuroSensor has created a new NTC thermistor specifically designed for medical equipment usage and targeted at sensing small temperature changes in the body and ambient medical area temperatures. With its high resistance design (2.25kOhm @25C), the ENTC-EB-2.2k3977-005 provides maximum sensitivity and a fast response time in the temperature range of 32C to 42C, where its resistance tolerance of +/-0.05C is ideal for high specification instrumentation and where temperature sensing, control and compensation are critical factors.

The new thermistor is encapsulated in a brown Stycast thermally conductive epoxy coating, and electrical interfacing is via two 76mm, 32AWG solid Alloy 180 leads. Its miniature form, measuring just 2.4 mm at the tip, will suit straightforward integration into many types of medical probes and in pharma and medical equipment. The sensor has a full operating temperature range of -40C to 125C.

The thermistor is part of a broad range of temperature measurement devices available from the company. It includes many other NTC and RTD thermistors, temperature probes, disposable medical probes, transducers, Hi-Rel and space-qualified thermistors, temperature switches, thermocouples, etc.
