T40B
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 T40B 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 dif­
ferences 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 Installation orientation

The torque flange can be installed with any orientation.
With clockwise torque, the output frequency is 60  90 kHz for Option 5,
Code DU2 (Option 5, Code SU2: 10  15 kHz; Option HU2: 240  360 kHz).
In conjunction with HBM amplifiers or when using the voltage output, a posit­
ive output signal (0 V  +10 V) is present. In the case of the rotational speed
measuring system, an arrow is attached to the stator housing to clearly define
the direction of rotation: If the measurement flange turns in the direction of the
arrow, connected HBM measuring amplifiers deliver a positive output signal.

4.4 Installation options

There are basically two options for mounting the torque flange: with or without
dismantling the antenna ring. We recommend mounting as described in
Chapter 4.4.1. If mounting in accordance with 4.4.1 is not possible, (e.g. in the
case of subsequent stator replacement), you will have to dismantle the
antenna ring. It is essential in this case to comply with the notes on assem­
bling the antenna segments (see Chapter 4.4.2).
