The model R40403CS29 identifies the specific Magnehelic family configuration, providing switch actuation when the sensed differential crosses the set threshold. Designed for industrial environments, this pressure switch can be used to sense pressure differences across filters, in ducts, or other components and to produce an electrical signal to control equipment or alert systems as part of HVAC or process-control setups. With its 0–2 in. water range, it is suited to detecting small pressure differences that indicate filter loading, airflow changes, or system balance, enabling reliable monitoring in demanding applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"CS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51680022659374,"sku":null,"price":44.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_720a67ff-ee33-42d0-85af-0217b29f2106.jpg?v=1769617645","url":"https:\/\/plgautomation.com\/products\/industrial-r40403cs29-differential-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
