{"title":"Thermal compressed air flow switches","description":"\u003cp\u003eThermal compressed air flow switches monitor the air consumption of a machine or supply line and switch outputs at adjustable limits, for example at a leak or an unexpected peak in use. A heated sensor measures the flow with no moving parts and almost no pressure loss.\u003c\/p\u003e\u003cp\u003eEach of the two switching outputs is set to a limit in Nl\/min (normal liters per minute) and to PNP or NPN to match the control system, so a leak or an overload raises an alarm. The color display shows the current flow and the switch states.\u003c\/p\u003e\u003cp\u003eFour sizes fit R 1\/2\" to R 2\" pipes, rated to 16 bar (≈230 psi) with an 18 to 30 V DC supply. They are for compressed air only; for water-based liquids, choose a calorimetric flow switch. The same devices are also listed under thermal compressed air flow meters.\u003c\/p\u003e","products":[],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/1787\/6152\/collections\/cat-compressed-air-flow-meter.jpg?v=1793066560","url":"https:\/\/tameson.es\/collections\/thermal-compressed-air-flow-switches.oembed","provider":"Tameson.com","version":"1.0","type":"link"}
