Catalog excerpts

Torque Transducer Torque range 2 Nm to 1000 Nm for static applications active or passive-model • accuracy 0.15 % full scale • input for checking the device chain Suitable for • testing torque wrenches • precisely tightening screws • measurement of screwings on badly re achable places • measuring torque on screwings that are hard to reach • measuring the friction factor • measuring the load on flap valve This non-rotating torque transducer is suitable for checking different types of screwing tools or for use as a reference transducer in test benches. It is a low-cost alternative to the rotating torque transducer. When the supply voltage is input to the transducer and the transducer is not loaded a control signal is output which can be used to adjust the chain.
