In ASCO’s S-Series, the transducer unit and switch unit are supplied as separate components that are ordered together by catalog number joined with a slash (for example TD30A21\/SA31DV). The TD30A21 transducer part provides the pressure-sensing element and converts pressure into an electrical signal that drives the switch portion; the SA31DV switch unit contains a snap-action electrical contact that changes state when the sensed pressure reaches the setpoint. This Tri-Point configuration supports multiple switching actions from a single pressure input, enabling straightforward integration with control circuits for pumps, compressors, or processing equipment. Typical installations leverage ASCO’s two-component architecture to tailor setpoints and response characteristics for specific applications, while maintaining the robustness and repeatability typical of ASCO products. The combined TD30A21\/SA31DV arrangement embodies the established ASCO two-piece approach that customers rely on for precise pressure monitoring and reliable circuit interlock or alarm signaling in industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"ASCO","offers":[{"title":"New","offer_id":51660162367790,"sku":null,"price":798.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c567375b-a458-439a-a580-a83433d268d6.jpg?v=1769533791","url":"https:\/\/plgautomation.com\/products\/asco-td30a21-sa31dv-tri-point-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
