Conditions On Site; Installation Orientation - HBM T40S7 Mounting Instructions

Mechanical installation
An appropriate shaft flange enables the T40FM torque flange to be mounted
directly. It is also possible to mount a joint shaft or relevant compensating ele­
ment directly on the rotor (using an intermediate flange when required). Under
no circumstances should the permissible limits specified for bending moments,
lateral and longitudinal forces be exceeded. Due to the T40FM torque flange's
high torsional stiffness, dynamic shaft train changes are kept to a minimum.
Important
Even if the unit is installed correctly, the zero point adjustment made at the fact­
ory can shift by up to approx. 0.5% of the characteristic value. 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.

Conditions on site

The T40FM torque flange must be protected against coarse dirt particles, dust,
oil, solvents and moisture.
There is wide ranging compensation for the effects of temperature on the out­
put and zero signals of the transducer (see Chapter 14 "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.

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 con­
junction with HBM amplifiers or when using the voltage output, a positive output
