Torque Sensor Model 8627, 8628, 8632
6. Measuring
6.1 Engaging
The warming-up period of the torque sensor is approx. 5 min. Afterwards the
measurement can be started.
The warming-up period of the torque sensor is approx. 5 min.
6.2 Direction of Torque
Torque mains clockwise or clockwise torque if the torque acts clockwise when
facing the shaft end. In this case a positive electrical signal is obtained at the
output. Torque sensors by burster praezisionsmesstechnik gmbh & co kg can
measure both, clockwise and counter-clockwise direction.
6.3 Static / Quasi-Static Torques
Static and/or quasi-static torque is a slowly changing torque.
The calibration of the sensor occurs statically on a calibration device.
The applied torque may accept any value up to the nominal torque.
6.4 Dynamic Torques
6.4.1 General
The static calibration procedure of torque sensors is also valid for dynamic
applications.
Note:
The frequency of torques must be smaller than the natural frequency of the
mechanical measurement setup.
The band width must be limited to 70 % of the nominal torque.
