• Relationship between the Pulse Input Range and Pulse Rating of the
Torque Signal
If the torque sensor with the specifications below is used to measure the torque in the
range of –20 N·m to +20 N·m, the pulse input range and pulse rating settings are as
shown in the scree example below.
Specifications of the pulse output torque sensor
Pulse rating (positive): Outputs 15 kHz for 50 N·m
Pulse rating (negative): Outputs 5 kHz for –50 N·m
