Part of Barksdale’s DPD1T\/DPD2T family, the H18SS suffix denotes a hermetically sealed, stainless-steel version with welded wetted parts for rugged environments. It provides a fixed differential operating range from 0.4 to 60 psi (0.03 to 4.1 bar) with a maximum working pressure of 60 psi, and hosts two independent SPDT switching elements (DPD2T) on a common pressure port, using a 6-pin terminal block for wiring. The unit is UL and CSA listed and can be ordered with factory presets and NEMA 4 or 4X enclosures to suit indoor or outdoor installations; the hermetic 18SS variant is especially appropriate where moisture or contamination must be contained. Operating temperature spans -54°C to +74°C (-65°F to +165°F), enabling stable operation across diverse industrial environments. Typical applications include pump and compressor monitoring, HVAC control, engine monitoring, filtration systems, and other process-control duties where two alerts or controls are required from a single differential pressure source.\u003c\/p\u003e\u003c\/div\u003e","brand":"Barksdale","offers":[{"title":"New","offer_id":51676676194606,"sku":null,"price":326.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4e1f24a0-fad8-40d7-89c6-f16908ae80b1.jpg?v=1769552287","url":"https:\/\/plgautomation.com\/products\/barksdale-dpd2t-h18ss-pressure-vacuum-actuated-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
