Will the probe assembly be subjected to excessive thermal cycling and/or thermal shock? Littelfuse’s application engineers have extensive experience designing temperature probes capable of withstanding harsh environments. Littelfuse’s in-house environmental lab includes equipment capable of subjecting the sensor assemblies to thermal shock, thermal cycling, freeze/thaw cycling, salt water immersion, high temperature exposure, low temperature exposure as well as humidity cycling, all while under power and with continuous component data logging.
