Each type of irregular stress can only be permitted with its given limit value (bending moment, lateral force
or axial force, exceeding the nominal torque) if none of the others can occur. Otherwise the permitted limits
must be reduced. If for instance 30 % of the limited bending moment and also 30 % of the limited lateral
force are present, only 40 % of the limited axial force are permitted, provided that the nominal torque is not
exceeded.
1
Higher speed possible in clearance-free adaption.
2
Direct acting axial force on the shaft. If the force affects the snap ring, just 50 % of the force is permitted.

NCTE torque sensors
Series 2300
Scope of delivery
The torque sensor set consists of the sensor itself (signal pick-up and signal processing integrated into sensor
housing), one connecting cable 5 m with a soldered plug (binder plug no. 99-0426-10-08), key stones (round
shaft) and the calibration certificate.
USB-cable will be delivered in 2,80 m length.
Datasheets and instruction manuals are available at www.ncte.com.
Installation and removal
Make sure to install the sensor shafts exactly with the proper aligned connecting shafts. The key stone
adapter/square endings of the connecting shafts are to be attached forceless to the corresponding ones of
the sensor. No external axial force should be on the housing of the sensor from distortion. A maximum cable
length of 5 m must not to be exceeded. Using a cable or connector other than supplied by NCTE, or a similar
cable that is of a different length may affect the overall performance of the sensor.
Do not remove the shaft with torque applied to the sensor.
Interface description
Mechanical connection:
The key stone adapters on both ends of the measurement shaft are intended for torque transmission.
Electrical connector:
On the sensor housing there is a 8-pin socket for the power supply and the signal output (see chapter
connection plan).
Operation (in regular case or in optimal case)
Optimal measurement parameters can be achieved if the sensor is applied in accordance to the specification.
By compliance with the specification the sensor works generally trouble-free and maintenance-free.
Irregular operation, measures against disturbance
The mechanical overload on the sensor (e. g. exceeding of maximum allowed torque or severe vibrations)
may cause damage to the sensor and in consequence the incorrect signal output. In such cases please do not
open the sensor. Contact NCTE directly for assistance.
Commissioning
After sensor installation pay attention to the following:
Switch on the power supply unit and check the supply voltage. Peak voltage must be avoided! Be
sure to verify the power supply voltage before connecting the sensor!
Connect the sensor to the power supply unit by using the delivered cable.
Connect the sensor output to a high-resistance device such as an A/D converter, oscilloscope, PC
measurement board. The sensor should be in mechanical unloaded state while connecting it.

Shaft coating
The shafts are protected on both sides with a film of anticorrosion wax. We recommend to leave the
protection permanent. As far as technologically needed, the coating can be removed with spirit / ethanol
Handling and transportation
By handling, storage and transportation keep the sensor away from magnetic or electromagnetic fields which
may exceed the maximal intensity defined from EMC (chapter technical characteristics) for instance
degaussing machines.
Precautions
Do not open the sensor housing under any circumstances.
Do not remove or loosen the locking rings on the shaft ends.
Do not loosen or tighten the flange-mounting nut of the socket-connector (chapter dimensions).
Use only a separate power supply for the sensor.
Use the sensor only according to the specification (chapter technical characteristics).
