The torque sensor DRVZ provides a precise measurement of torque and angle of rotation when
testing systems that are driven by PTO shafts, such as a tractor gearbox.
The contactless transmission of supply voltage and measuring signal enables low-wear and largely maintenance-free continuous operation. The integrated measuring amplifier provides an analog and galvanically isolated output signal of 0 ± 10V or 10kHz ±5kHz with a supply voltage of 10 to 28.8V DC
