9. Measurement outputs
The transducer outputs a 0 – 10 V DC voltage that is proportional to the tor-
que. The output voltage is positive for clockwise torque, and negative for
counterclockwise torque. The transducer outputs a 10 kHz ± 5 kHz differential
frequency signal (RS422), as well.
The torque sensor has a permitted zero point deviation of ± 50 mV / ± 50 Hz. A
taring option must be provided for precise measurements.
Each of the speed and angle-of-rotation outputs has an active driver in the
system. The speed, angle and ready outputs deliver a TTL signal in the absence of
an external voltage reference.
The device also outputs a ready signal (Pin J): logic HIGH means the device is
ready, LOW means there is a fault in the device.
If a higher voltage output is needed, for PLC inputs, for example, a voltage
reference can be set through pin M. The voltage reference tolerates a 5 V - 24 V
voltage range.
10. Recalibration
We recommend, regardless of use, a recalibration (deadline see certificate) in
the house of ETH.
11. Disposal
The transducer along with the measuring cable can be returned free of charge to
us for disposal. As soon as you have packaged the transducer, send us an e-mail
at sales@eth-messtechnik.de. We will then instruct our parcel service to pick it
up.
We are sorry, but we cannot accept any goods sent to us unannounced and
freight-collect.
