Use as a machine element
The torque flange can be used as a machine element. When used in this man
ner, it must be noted that, to favor greater sensitivity, the transducer is not
designed with the safety factors usual in mechanical engineering. Please refer
here to the section "Load-carrying capacity limits", and to the specifications.
Accident prevention
According to the prevailing accident prevention regulations, once the transduc
ers have been mounted, a covering agent or cladding has to be fitted as fol
lows:
S
The covering agent or cladding must not be free to rotate.
S
The covering agent or cladding should prevent squeezing or shearing and
provide protection against parts that might come loose.
S
Covering agents and cladding must be positioned at a suitable distance or
be so arranged that there is no access to any moving parts within.
S
Covering agents and cladding must still be attached even if the moving
parts of the torque flange are installed outside peoples' movement and
working range.
The only permitted exceptions to the above requirements are if the torque
flange is already fully protected by the design of the machine or by existing
safety precautions.
Additional safety precautions
The torque flange cannot (as a passive transducer) implement any (safety-rele
vant) cutoffs. This requires additional components and constructive measures,
for which the installer and operator of the plant is responsible. The electronics
conditioning the measurement signal should be designed so that measurement
signal failure does not subsequently cause damage.
