Abstract:

Development of a temperature controller for the hot end of a Vuilleumier VM cryogenic cooler system is presented. The objectives of a low- cost, moderate reliability, environmentally tested controller are met in the design presented. Fundamental design factors include use of an onoff controller operating from the 28-volt aircraft bus, use of a platinum resistance temperature sensor, packaging within 25 cubic inches, use of class P components, and an estimated mean-time-between-failure of more than 8000 hours.
