Important
Even if the unit is installed correctly, the zero point adjustment made at the
factory can shift by up to approx. 0.5% of the sensitivity. If this value is
exceeded, we advise you to check the mounting conditions. If the residual
zero offset when the unit is removed is greater than 1% of the sensitivity,
please send the transducer back to the Darmstadt factory for testing.
5.2 Conditions on site
The torque flange must be protected against coarse dirt particles, dust,
oil, solvents and humidity.
There is wide ranging compensation for the effects of temperature on the out-
put and zero signals of the transducer (see “Specifications" section). If there
are no static temperature ratios, for example, because of the temperature
differences between the measuring body and the flange, the values given in
the specifications can be exceeded. In this case, ensure static temperature
ratios by cooling or heating, depending on the application. As an alternative,
check if thermal decoupling is possible, e.g. by means of heat radiating
elements such as multiple disc couplings.
5.3 Installation orientation
The torque flange can be installed with any orientation.
With clockwise torque load, the output signal is from 10 kHz to 15 kHz
corresponding zero to nominal torque load.
