AMTI / SF1.75D Waterproof IP68 Stainless Steel Force-Torque Sensor

The SF1.75D is an underwater multi-axis transducer with a stainless steel body (Ø1.75 in.) designed for applications involving submersion in fresh water. The sensor is oil-filled and pressure compensated with an IP rating of 68. It features 19-pin Glenair output connector. The SF1.75D transducer incorporates a unique design that essentially eliminates the effect of hydrostatic pressure on the output.
