Ametherm has rolled out a series of interchangeable thermistors that promise long-term stability and reliability for high-accuracy temperature sensing, control and compensation. The ACCU-Curve series thermistors are offered in a range of resistance values, with tight tolerances of ±0.2°C between zero and 70°C and fast thermal response times, detailed the company.

According to Ametherm, the ACCU-Curve series devices deliver the tight tolerances required for temperature measurement in critical medical instrumentation, and they can be potted in a variety of housings for temperature compensation circuits in industrial and automotive applications. They also give designers faster, less-expensive alternatives to RTD probes and thermocouples, without compromising on accuracy, the company added.

Offering diameters of 2.4mm and 32 AWG tinned-copper leads, the epoxy-coated thermistors are available in four resistance values at 25°C, 2.252 kΩ, 3kΩ, 5kΩ and 10kΩ, with a dissipation constant of 1mW/°C and thermal time constant of 10s.

The devices are available direct or through distributors such as Digi-Key and Mouser. Samples and production quantities of the thermistors are available now, with factory lead times of 12 weeks.
