These 2-inch and 2-1/2 inch temperature gauges feature built-in electrical switches for activating alarms and/or shutting down equipment and offer real-time accuracy to a fraction of a degree.
These vapor-actuated gauges feature a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gauge reading.
All models in the Swichgage 20T, 25T, A20T, and A25T lines are diaphragm actuated, temperature-indicating gages with built-in electrical switches for tripping alarms and/or shut-down devices. Instruments in the A20T and A25T lines are fully sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel, and O-ring seals.
For series 20T and 25T, the gauge pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are grounded through the case. They have a self-cleaning motion to enhance electrical continuity.
Top features and benefits include:
* Wide Range Capability: Ranges are available from 32°-120° F (0°-45° C) through 300°-440° F (160°-220° C)
* Durable Housing: All models of these rugged, built-to-last instruments are fully sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel and O-ring seals..
Swichgage® instruments are built in the USA and for over 80 years, they have monitored engine coolant, crankcase oil, and transmission oil. MurCal experts help farmers, factory floor managers, water district engineers and more find the best Swichgage or Murphy gage for their application.
