It uses a 1\/8 in NPT connection for straightforward installation into ducts, piping, or instrumentation ports, making it suitable for integrating into control or monitoring circuits that respond to low differential pressures. The 1823-0 designation identifies this specific Dwyer model among its line of differential pressure switches, which are designed for reliable actuation at small pressure differentials. With its low-differential range, the switch is intended to provide a clear, repeatable signal in compact installations where precise threshold detection is required to drive automation or alert signaling.\u003c\/p\u003e\u003c\/div\u003e","brand":"DWYER","offers":[{"title":"New","offer_id":51681587233070,"sku":null,"price":52.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c4a332d2-7678-41d8-bbd5-1c2b184a438b.jpg?v=1769635233","url":"https:\/\/plgautomation.com\/products\/dwyer-instruments-1823-0-differential-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
