The Ashcroft P Series temperature switch features a SAMA Class II vapor pressure thermal system. This system provides a quick and accurate response to process temperature changes with minor ambient temperature effects. This is inherent in the design due to the precise relationship that exists between temperature and pressure according to the vapor pressure laws. A wide selection of sensing bulb and armored capillary lengths are available. The vapor pressure system design features small bulb sizes, making installation easy and cost-effective.

All models feature ±1% of span set point repeatability with very high over temperature ratings. These standard designs perform well in applications where shock and vibration are potential problems and should be used with Ashcroft thermowells for bulb protection and ease of installation and maintenance.
