This 1\/2 in NPT ported device uses Bellofram’s Type 1000 current-to-pressure architecture and is designed for industrial control applications that require a precise, repeatable 3-15 psi output in response to PLC or instrumentation signals. Input is 4-20 mA and the pneumatic output is 3-15 psi, with a supply pressure maximum of 100 psi. The unit is designed for use with instrument-quality air, and the model 221-961-070 is the 4-20 mA input variant of the Type 1000 series; it has been discontinued by the manufacturer and superseded by the 961-070-000 variant. Typical uses include automation control loops, pneumatic actuator actuation, and process control where a current loop must be converted to a stable, low-pressure pneumatic signal. Port size is 1\/2\" NPT for straightforward plumbing, and the 18-100 psi air supply range supports integration with standard shop air systems. This transducer is compatible with standard 4-20 mA signaling in industrial instrumentation, providing a direct path from electrical control to pneumatic actuation.\u003c\/p\u003e\u003c\/div\u003e","brand":"Bellofram","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676876636462,"sku":null,"price":47.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_1b64c126-5861-487a-a465-23964ddca74f.jpg?v=1769554659","url":"https:\/\/plgautomation.com\/products\/bellofram-221-961-070-pressure-transducer-4-20ma-output","provider":"PLG Automation ","version":"1.0","type":"link"}
