b) Non-contact sensor: in the sensor working stroke, the signal is obtained by
magnetic coupling, electrical coupling, optical coupling, etc. (such as the sensor
with coil induction, Hall effect, giant magnetic (MR) bridge, capacitive electric
field, and other principles).
4 Technical Requirements
4.1 General requirements
4.1.1 Sensor.
The sensor is manufactured according to the product drawings and technical
documents approved byte prescribed procedures.
4.1.2 Working temperature.
The sensor shall work properly in the temperature range of -40°C~+85°C or +105°C
(the sensor for automobile electrical power steering is installed outside the cab).
4.1.3 Relative humidity.
The relative humidity that the sensor can withstand shall be ≤95%RH.
4.1.4 Sensor power supply or auxiliary working power.
The sensor power supply uses a DC regulated power supply of 24V or less.
4.1.5 Test apparatus equipment.
4.1.5.1 In the temperature range of 23°C±5°C, the measurement accuracy of the
torque, (angle) displacement, current, and voltage shall be no less than 0.5%FS.
4.1.5.2 In the temperature range of 23°C±5°C, the resolution of temperature
measurement shall be no less than 1°C.
4.1.5.3 In the temperature range of 23°C±5°C, the resolution of humidity
measurements shall be no less than 10%RH.
4.1.6 Resistance to industrial solvent.
The resistance to industrial solvent of sensor shall conform to the provisions of 3.14 in
QC/T 413.
4.1.7 Surface protection properties.
The surface protection properties of the sensor shall conform to the provisions of 3.15
