Conditions On Site; Installation Orientation - HBM T40B Mounting Instructions

no circumstances should the permissible limits specified for bending moments,
lateral and longitudinal forces be exceeded. Due to the T40B 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 fac­
tory 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.

Conditions on site

The T40B 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 "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.

Installation orientation

The torque flange can be installed with any orientation.
With clockwise torque, the output frequency is 60 to 90 kHz for Option 5, Code
DU2 (Option 5, Code SU2: 10 to 15 kHz; Option HU2: 240 to 360 kHz). In con­
junction with HBM amplifiers or when using the voltage output, a positive out­
put signal (0 V to +10 V) is present. In the case of the rotational speed measur­
ing 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.
