The 1638-2 triggers its switch when the 10 PSI threshold is reached, providing a simple electrical signal for control or alarm applications. It’s designed for monitoring pressure differences in systems where a fixed differential threshold governs downstream equipment or safety controls.\u003c\/p\u003e\u003c\/div\u003e","brand":"Dwyer","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51681621082414,"sku":null,"price":268.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_99079004-53d6-4834-a272-49e7a0edac7f.jpg?v=1769635327","url":"https:\/\/plgautomation.com\/products\/dwyer-instruments-1638-2-differential-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
