Type 4502A... torque sensors operate on the strain gage principle
and supply an analog output signal of ±0 ... 5 V which
is contactless transferred. Available also with integrated rotational
angle/speed measurement.
? Smart (integral measuring electronics)
? Interference resistance due to active torque output (±5
VDC), electrically isolated from supply and measuring signal
? Non-contact signal transfer
? Unipolar supply
? Highly responsive to dynamic peaks
? Maintenance-free
? Standardized mechanical connections:
– 1/4" hex socket DIN3126
– Square socket (size depending on measuring range)
– Cylindrical shaft ends
? Extremely compact
? Suitable for pulse tool operation
? Optional rotational angle measurement
Description
The Mini-Smart torque sensor uses strain gage technology.
The torque signal is transmitted from the rotating shaft via
frequency modulation and is processed as an analog signal.
The rotational angle signal with two tracks of each 360 pulses
per revolution and track is available as TTL-signal. An external
electrical control input is standard.
Application
The Mini-Smart torque sensor with rotating measuring shaft
is suitable both for dynamical detection of starting torque and
breakway torque for bolting and assembly techniques and for
quality assurance in production and laboratory.
Due to its standardized connections the device can be quickly
adapted to air, electronic and pulse tools.
