4.1 Conditions on site

The T10FM torque flanges are protected to IP54 according to EN 60529.
They must be protected against coarse dirt particles, dust, oil, solvents and
humidity . During operation, the prevailing safety regulations for the security of
personnel must be observed (see "Safety instructions").
The output- and zero signals of the T10FM torque flange are compensated for
the effects of temperature variations between wide limits (see specifications
on page 42). This compensation is carried out at static temperatures. This
guarantees that the circumstances can be reproduced and the properties of
the transducer can be reconstructed at any time.
If there are no static temperature ratios, for example, because of the tempera-
ture differences between flange A and flange B, the values given in the speci-
fications can be exceeded. Then for accurate measurements, static tempera-
ture ratios must be obtained by cooling or or heating depending on the
application. Alternatively, temperature decoupling must be checked, e.g. by
heat radiating elements such as laminated couplings.

4.2 Mounting position

The gaging flange can be mounted in any position. With clockwise torque, the
output frequency is 10 – 15 kHz. With HBM amplifiers or when using the vol-
tage output, a positive output signal (0 V to +10 V) is present.
In the case of the speed measuring system, an arrow is attached to the head
of the sensor to clearly determine the direction of rotation. If the gaging flange
moves in the direction of the arrow, the connected HBM measuring amplifiers
give off a positive output signal (0 V...+10 V).

4.3 Installation possibilities

On principle, there are two possibilities for torque flange mounting: with an-
tenna ring complete or disassembled. We recommend to proceed as descri-
bed in chapter 4.3.1 . If mounting in accordance with 4.3.1 is not possible,
(e.g. in the case of a subsequent stator replacement or mounting with the
speed measuring system), you will have to undo the antenna ring. It is essen-
tial in this case to comply with the notes on assembling the antenna segments
(see "Installing the stator" and "Installing the slotted disc").
