This very popular design features a diaphragm-actuated, temperature-indicating gage, with a built-in electrical switch for tripping alarms and\/or shutdown devices.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThis model has a 6-foot capillary length with a standard 1\/2-14 NPT threading, and a temperature range from 130-250°F (54-121°C). The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThis 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.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eInside the 20T-250-6-1\/2, the gage 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 Swichgage® case. This gage has a self-cleaning motion to enhance electrical continuity.\u003c\/span\u003e\u003c\/p\u003e","brand":"Murphy","offers":[{"title":"Default Title","offer_id":47961233293534,"sku":"20T-250-6-1\/2","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/8985\/5966\/files\/10702043_01_cd9232ef-7015-4036-8088-0e1abbd5c892.avif?v=1772928228","url":"https:\/\/www.aandlsystems.com\/products\/20t-250-6-1-2-temperature-switchgage","provider":"A\u0026L Systems NexGen","version":"1.0","type":"link"}
