4.1 Conditions on site
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").
There is wide ranging compensation for the effects of temperature on the
output and zero signals of the T10FM torque flange (see Specifications on
Page 46). This compensation is carried out at static temperatures in extensive
furnace processes. 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
temperature differences between flange A and flange B, the values given in
the specifications can be exceeded. So, for accurate measurements, static
temperature conditions must then be obtained by cooling or heating
depending on the application. As an alternative, check thermal decoupling by
means of heat radiating elements such as multi‐disc couplings.
4.2 Installation orientation
The measurement flange can be mounted in any position. With clockwise
torque, the output frequency is 10 ... 15 kHz. In conjunction with HBM
amplifiers or when using the voltage 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 define the direction of rotation. If the measurement
flange turns in the direction of the arrow, connected HBM amplifiers deliver a
positive output signal (0 V...+10 V).
4.3 Installation options
In principle, there are two possibilities for torque flange mounting: with the
antenna ring complete or dismantled. We recommend mounting as described
in Chapter 4.3.1 . If installation in accordance with 4.3.1 is not possible, (e.g.
in the case of subsequent stator replacement or mounting with a speed
measuring system), 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 "Mounting the stator" and "Mounting the slotted disc").
