Designed for industrial combustion applications, it senses changes in vacuum within the burner or draft system and provides a switch output when the differential crosses the setpoint. The S‑Series arrangement consists of a separate transducer unit and switch unit, enabling modular configurations that can be field‑ or factory‑assembled to suit different installation needs. This exact TA20A31W\/SB31D combination is part of ASCO’s legacy line of vacuum and differential switches used in combustion safety applications.\u003c\/p\u003e\u003c\/div\u003e","brand":"ASCO","offers":[{"title":"New","offer_id":51660162498862,"sku":null,"price":231.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4d2cb08d-1308-4d1d-9575-ef8c354029e3.jpg?v=1769533793","url":"https:\/\/plgautomation.com\/products\/asco-ta20a31w-vacuum-deferential-combustion-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
