2Safety
Please note the enclosed sheet on the warning notes.
2.1 Intended use
The sensors of the series 2300 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 Duration of use
A factory recalibration should be executed annually. See corresponding label on the sensor.
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 2300
The 2300 series is the most cost-effective entry into professional torque measurement technology.
3.1 Short description
This series is mainly used in automotive test facilities, professional testing construction, climatic exposure
test cabinets (exceeding dew point), process monitoring and medical engineering.
Transmitted torque can be measured statically and dynamically in real time. Each sensor can be configured
individually with a lot of extras, such as angle sensor.
Series 2300 offers a wide range of output signals such as 0-10 V, 4-20 mA, CAN-Bus or USB. USB is offered
including a special NCTE software enables to show data in real time.
The sensor is provided as a complete unit with integrated evaluation electronic, including 5 m cable,
keystones and factory calibration certificate and in case of digital output 2.8 m USB cable is also included.
3.2 Assembly and disassembly
When mounting the sensor, make sure that the measuring shaft is exactly aligned with the connecting shafts.
It must then be possible to push the key adapters of the connection shafts onto the key adapter connections
of the sensor without any effort. No force must be exerted on the housing in the axial direction during
fastening. The sensor can be secured against rotation by means of the flat surface (optional sensor holder).
The cable length must not exceed 5m. Using a cable other than the one supplied by NCTE or an identical cable
with a different cable length may impair the function of the sensor system.
The disassembly may only be done without applying torque to the measuring shaft.
3.3 Interface description
Mechanical interfaces:
For power transmission, adapter connections are provided at both ends of the keystone round shafts.
Electrical interface:
A socket for power supply and signal output is attached to the upper side of the housing.
(Pin assignment see Chapter “7 Wiring diagram")
3.4 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.
(e.g. A/D converter, oscilloscope, PC measuring card)
•Record output signal in mechanically unloaded state of the sensor.

3.5 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.
3.6 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.
3.7 Safety instructions
The following safety instructions should be followed for smooth operation:
•Opening the sensor or even single screws is not allowed.
•The shaft retaining rings on the shaft ends must not be loosened.
•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.
3.8 Shaft preservation
The shafts are protected on both sides with a film of anti-corrosion wax. We recommend to leave the
protection permanently. If technically necessary, remove the protective film with spirit/ethanol.
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.

Note: In case of overload, the sensor leads to an offset in measurement. In such case, the sensor needs to be
recalibrated at NCTE AG. The sensor should be operated only within the specified nominal torque range.

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.

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.
