2Safety
Please note the enclosed sheet on the warning notes.
2.1 Intended use
The sensors of the Series 7000 are designed exclusively for measuring torque and/or speed. The respective
load range can be taken from the data sheet and must not be exceeded.
Proper use also includes compliance with the commissioning, assembly, operating, ambient and maintenance
conditions specified by the manufacturer.
Any use beyond these is considered improper. The manufacturer is not liable for any damage resulting from
such use.
2.2 Recalibration and duration of use
A factory recalibration should be executed annually. See the corresponding label on the sensor.
This recalibration can be carried out quickly and easily by NCTE AG.
Please contact us.
If the sensor is used within the limits of its intended use and regularly calibrated, the sensor's operating life
is unlimited.
2.3 Structural change
Unauthorized conversions or changes to the torque measuring system are prohibited for safety reasons and
lead to the immediate expiration of the warranty claims.
2.4 Training of the operating personnel
Assembly, commissioning and maintenance personnel must have read and understood the complete
operating instructions, especially Chapter “2 Safety". The operator is recommended to have this confirmed
in writing.
2.5 Transport and handling
During handling, storage and transport, make sure that the sensor is not exposed to strong magnetic or
electromagnetic fields (e.g. degaussing coils).

3Torque 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.

3.5 Starting up
After mounting the sensor, the following must be observed:
Switch on power supply and check voltage value.
(Voltage peaks at the sensor must be avoided, devices must be checked accordingly before
connection to the sensor)
Connect the sensor to the power supply. (using the cable supplied)
Record the output signal of the sensor with high resistance. (A/D converter, oscilloscope, PC)
Record output signal in mechanically unloaded state of the sensor.
3.6 Operation during regular mode
Optimal measuring values are achieved when the sensor is used while maintaining the specific nominal
torque. If the permissible operating conditions are observed, the sensor operates trouble-free and
maintenance-free.
3.7 Irregular operation, actions in case of failures
If the sensor is mechanically overloaded (e.g. if the maximum permissible longitudinal force or torque limit
is exceeded or if there are strong vibrations), the sensor may be damaged and the signal output may be
distorted. In this case do not open the device. Contact NCTE AG directly.
3.8 Safety instructions
The following safety instructions should be followed for smooth operation:
Opening the sensor or even single screws is not allowed.
The fastening nut of the plug must not be loosened or tightened.
Only use power supplies safely disconnected from the mains voltage.
Regarding the electrical and mechanical load of the sensor, the specifications according to the
sensor-specific nameplate and the table in Chapter “4 Technical characteristics” must be observed.
The sensor is not to be used as support bearing. The existing fastening options serve exclusively to
secure the housing against twisting.
To protect your system, we recommend increasing the torque over several stages.
3.9 Service, maintenance and repair
As part of your test and measurement equipment management, we recommend regular inspection of your
test and measurement equipment. Please also observe the relevant standards and guidelines.
Maintenance plan by NCTE AG
Calibration: Every 12 months
Check the wiring, connectors and shaft: Every 12 months
Repairs and recalibrations can only be carried out by NCTE AG personnel.
3.10 Disposal
The device must be returned to NCTE AG, Raiffeisenallee 3, D-82041 Oberhaching for disposal.

Any irregular stress (bending moment, transverse or axial force, exceeding the nominal torque) up to the
specified static load limit is only permissible as long as none of the other stresses can occur. Otherwise the
limit values must be reduced. If 30 % of the limit bending moment and 30 % of the limit transverse force are
present in each case, only 40 % of the axial force is permissible, whereby the nominal torque must not be
exceeded.
4Technical characteristics
1
Specified values only apply to direct axial force on the shaft. If the axial force acts on the circlip, only 50 % of the force is permissible.
2
The accuracy class means that the linearity deviation as well as the circulation modulation, individually, are each less than or equal to the value
specified as the accuracy class. The accuracy class must not be confused with a classification according to DIN 51309 or EA-10/14.
