Flange-to-square Reaction Torque Sensor RTT06 has been designed specifically for the measurement of direct torque, and is particularly suited for use in calibrating or testing torque tools in a QA environment. Made from stainless steel, stationary torque transducer RTT06 features a flange on one end which can be used to mount the sensor to a flat and solid surface, and a 3/4 inch square on the other end to connect with torque sleeve for loading. Based on proven strain gauge technology, rated capacities of square drive torque sensor RTT06 available are 20Nm, 50Nm, 100Nm, 200Nm, 300Nm and 500Nm with less than 0.2% full scale non-linearity, suitable for bi-directional torque measurement in both CW and CCW direction. Model RTT06 offers a unique solution for auditing and calibrating mechanical torque wrenches, also used in production and automated assembly applications. Torque meter RTT06 can be modified or customized to meet your requirements.
