7. Description:
The B903 Flange to Flange Reaction Torque Sensor can accommodate applications that include automotive braking, engine and transmission dynamometers, torque table, fastener testing, aircraft engine testing, and marine shaft torque measurements with shaft horsepower monitors. The B903 is available in both, aluminum and stainless steel construction and offers a unique solution for torque auditing applications. This particular Reaction Torque Sensor can be used to evaluate low-torque components and controls. Flange-reaction torque sensors measure small-reaction torque levels using flange-to-flange connections in-line with the component under test.
