Variohm expands NTC thermistor range
24/02/2023
Variohm EuroSensor has launched a new specialist 10k variant aimed at mid-range temperature sensing tasks for tight-tolerance instrumentation in non-condensing moisture environments. The ENTC-EI-10k9777-02 thermistor is based on a Stycast epoxy encapsulated core with Kynar insulation for maximum durability across a –40°C to 125°C temperature range. Its high-sensitivity specification of 10k Ohm at 25°C and ±0.2°C resistance tolerance over 0°C to 70°C delivers precision sensing for heating, ventilation and air conditioning (HVAC), power and utilities equipment, renewables, industrial and laboratory instruments, plus many other areas.
The ENTC-EI-10k9777-02 thermistor has a fast time constant value of 1.5 s in liquids and other notable specifications include a beta value 25/85 constant of 3976K ±0.5% and a dissipation factor in still air of around 2 mW/°C. Measuring just 2.4 mm at its widest point and with 250 mm-long white Kynar-insulated silver-plated copper leads (28 AWG), straightforward installation is said to be guaranteed.
The expanding ENTC series from Variohm EuroSensor includes other hermetically sealed, glass or epoxy encapsulated negative temperature coefficient (NTC) thermistors. With a wide choice of optimal measurement temperature ranges, operating temperatures, tolerances and time constants, etc, application areas include, but are not restricted to, automotive, refrigeration, industrial instrumentation, medical equipment and more.
Variohm also supplies many other temperature-sensing devices in its comprehensive product range, including other NTC and resistance temperature detector (RTD) thermistors, specialist temperature probes, transducers, disposable medical probes, HI-REL and space-qualified thermistors, temperature switches, thermocouples and more.
