These torque sensors are designed to insert between a squaredrive torque producing device and the work fixture it is attached to. This allows direct static and limited rotation torque measurements while the tool or device is placed under its typical load. A valuable torque measuring solution for testing drive socket systems, calibrating hand and click wrenches and checking applied torque values. Available in ten different torque capacities ranging from 25 inlb to 7,000 ftlb, all use a full, four-arm Wheatstone bridge circuit and have elastomer coating to protect the measurement element from mechanical damage. A six-foot 4-conductor shielded cable (terminated in a pigtail) allows the sensors to interface with a variety of test instruments by means of using different connector plugs (not supplied).
