Description
Rotating Torque Sensor DRBK + DRBK-A
Series DRBK torque transducers are suitable for lab and industrial applications because of their small size and multiple mounting options. As supply voltage and output signal are transmitted without contact, the device can operate continuously with low wear and no maintenance. These transducers are also available with speed measurement for a host of applications. The integrated signal amplifier runs on 11.5 to 30 V DC; it outputs an analog signal of 0 to ± 5 V and a current signal of 10 mA ± 8 mA. Due to its large supply voltage range the transducer can be operated directly from a PLC. The device should be used only with couplings designed specially for it.
Note: This transducer should only be used in conjunction with the specially developed couplings.
