This diaphragm-actuated, 2\" temperature-indicating gage has a built-in electrical switch for tripping alarms and\/or shutdown devices.\u003cbr\u003eThis model has a polished stainless steel bezel, a 4 foot capillary length, a temperature range from 130-250°F (54-121°C), and standard 1\/2-14 NPT threading. This vapor actuated gage features 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 gage reading.\u003cbr\u003eThe gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts are isolated through ground. This gage has a self-cleaning motion to enhance electrical continuity.\u003c\/p\u003e","brand":"Murphy","offers":[{"title":"Default Title","offer_id":47961446842590,"sku":"A20T-250-4-1\/2","price":139.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/8985\/5966\/files\/10703159_01.jpg?v=1772947047","url":"https:\/\/www.aandlsystems.com\/products\/a20t-250-4-1-2-temperature-swichgage-10703159","provider":"A\u0026L Systems NexGen","version":"1.0","type":"link"}
