BETA Temperature Switches

The BETA temperature switch is based on the approved pressure switch with an integrated 2-phase- (gas/liquid) temperature sensor. If process temperature increases, also the vapor pressure of the liquid increases. If pressure exceeds the defined response pressure value then the micro switch will be activated.

Each housing can be supplied with a direct sensor or a capillary connection (up to 10m). Weather-proof and ATEX-approved versions suited for all standard temperature protection sleeves. If ambient temperature is changing, no compensation is necessary (no drifting of the switching point), the repeatability is high and hysteresis low. Sensor and capillary (flexible armoring) are made from stainless steel 316 SS. Capillary is filled according to SAMA-Class II C.
