Torque Sensor Series 7000
The series 7000 opens up the segment of extremely robust and extremely resilient torque sensors in high
nominal torque ranges (up to 5000 Nm).
3.1
Short description
The Series 7000 is mainly used in test benches, automotive engineering (off-highway and agricultural) as well
as production monitoring and quality assurance.
With the Series 7000 torques can be measured statically as well as dynamically in real time. The sensor is
available for use in the agricultural industry with a wide range of PTO connections, a flange version is available
for variable connection. Each sensor can be configured individually, there is also the option of an angle sensor
or. Each sensor can be configured individually, there is also the option of an angle sensor or speed sensor.
The Series 7000 also offers a wide range of signal outputs. 0-10 V, 4-20 mA,
CAN bus or USB. The USB output is included with the appropriate NCTE software, enabling plug & play data
to be displayed on a screen in real time.
The sensor is supplied as a ready-to-connect unit including 5 m cable and calibration certificate.
3.2
Assembly and disassembly
When mounting the sensor, it must be ensured that the flat surfaces of the flanges are in clean contact. The
screws must be tightened crosswise in several steps to the nominal torque. These are cylinder-head screws
of quality 12.9 in size M12. The final tightening torque is 155 Nm. When fixing, no force must be exerted on
the housing in the axial direction. The sensor is not designed as a support bearing. The cable length must not
exceed 5m. If a cable other than the one supplied by NCTE or an identical cable with a different cable length
is used, the function of the sensor system may be impaired.
The M8 thread on the flattened side of the housing may only provide an anti-twist protection. The maximum
tightening torque for fixing is 25 Nm.
The disassembly may only be carried out without applying torque to the measuring shaft.
3.3
Adjustment
If required, the zero point output signal (5 V or 12 mA) can be adjusted. The sensor is factory set so that 5 V
or 12 mA corresponds to a torque of 0 Nm.
3.4
Interface description
Mechanical interfaces:
Flanges are provided at both ends of the sensor for power transmission.
Electrical interface:
A flange socket for power supply and signal output is attached to the top of the housing.
