Important
Even if the unit is installed correctly, the zero point adjustment made at the factory can shift
by up to approx. 2% 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.
4.2 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 output and zero
signals of the transducer (see Chapter "Specifications"). 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.
4.3 Mounting position
The T40HS torque flange can be mounted in any position
.
With clockwise torque, the output frequency is, depending on the option, 60 - 90 kHz, 10 -
15 kHz or 240 - 360 kHz). With HBM amplifiers or with the voltage output option, a positive
output signal (0 V -+10 V) is present.
4.4 Installation options
For T40HS torque flange mounting you will have to dismantle the antenna ring. It is
essential in this case to comply with the notes on assembling the antenna segments (see
Chapter 4.4.1).
