Measurement Specialties’ 44900 series thermistors, which feature high sensitivity and interchangeability to ±0.1°C, are suited for use in extended flight applications. The NASA-qualified, epoxy encapsulated, precision NTC components feature resistance of 2252 ohm to 30 K ohm at 25°C. Thermally conductive epoxy coating exhibits less than 0.66% total mass loss, less than 0.01% collected volatile condensable material, and 0.10% water vapour regained when tested per ASTM E-specs, making the thermistors suitable for extended space applications, low- and mid-range temperature applications, tight-tolerance instrumentation, applications requiring sensing of small changes in temperature, and applications with degassing requirements.
