1. Short description

With this torque sensor the effective torque on the gauge bar can be measured bi-directionally independent

from rotational speed. The sensor is delivered as a complete unit with corresponding connecting cable and key

stones. The transmitting shaft, the contact-free signal pick-up and the analog signal processing are integrated

into the sensor structure. No external amplifier is needed. Based on magnetic field and therefore completely

non-contact measurement principle the sensor works totally maintenance-free over a wide temperature range.

Torque Sensor Series 3000 and Series 4000 www.ncte.de Commissioning After sensor installation pay attention to the followings: •Switch on the power supply unit and check the supply voltage. Peak voltage to the sensor 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.

Except the sensor type this certificate also contains the exact calibration data. Each sensor has its own calibration value which is listed in the calibration certificate as well as on the label of the sensor. The calibration certificate also shows the accuracy of each sensor.
