Ashcroft L-Series temperature switches feature a SAMA Class II vapor pressure thermal system. This system provides a quick and accurate response to process temperature changes with minimal effects on the ambient temperature. This is inherent in the design due to the precise relationship 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 a potential problem and should be used with Ashcroft thermowells for bulb protection and ease of installation and maintenance.
