A polycarbonate, break resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. These vapor actuated gages 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 gage reading. \u003cbr\u003e\u003cbr\u003eFor series 20T, the gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. \u003cbr\u003e\u003cbr\u003e20TE (was 20ESR) are Models with internal SPDT snap-switches, instead of the single pole\/pointer contact(s). When the switch closes on rising temperature, it becomes Set. As temperature decreases the switch Resets.  \u003c\/p\u003e","brand":"Murphy","offers":[{"title":"Default Title","offer_id":47961445761246,"sku":"20TE-250-4-1\/2","price":159.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/8985\/5966\/files\/10702499_01.jpg?v=1772946803","url":"https:\/\/www.aandlsystems.com\/products\/20te-250-4-1-2-temperature-switchgage-10702499","provider":"A\u0026L Systems NexGen","version":"1.0","type":"link"}
