3 Classifications
Sensors shall be classified into 3 types – resistance-type, capacitance-type, and
pressure-type. Resistance-type sensors are divided into 2 types - reed
variable-resistance sensors, and sliding variable-resistance sensors.
4 Requirements
4.1 General provisions
4.1.1 Product documentation.
4.1.1.1 The sensors shall conform to the requirements of this standard. And it shall be

provisions of the product drawings.
4.10 Durability
The sensor shall be able to withstand 30,000 times of alternating cycle inspections. Its
parts shall have no abnormal changes during the inspection. After the inspection, the
variation of indication value shall not exceed 7% of the nominal value of the measured
point; it shall conform to the provisions of 4.3, before and after the inspection.
4.11 Oil resistance
The sensor shall be able to withstand the immersion in the alcohol, gasoline or diesel.
After the inspection, the mechanical part and rubber part shall be free of the defects
such as deformation, color change and cracks. And it shall conform to the provisions
of 4.3 and 4.4.
4.12 Gas tightness
For gas tightness inspection, pressure gauge reading of the sensor shall remain
unchanged in 10s. And no bubbles shall occur at the sealing part.
5 Test methods
5.1 Test conditions
5.1.1 Output value test of the sensor shall be conducted under the environment
conditions specified in 4.1.2.
5.1.2 The accuracy of digital multimeter for the test shall be ± 0.5.
5.1.3 The accuracy of steel gauge shall be ± 1mm.
5.1.4 The accuracy of standard thermometer shall be ± 1°C.
5.2 Appearance
For appearance inspection, it shall be inspected with an average illumination of about
3001x; eye distance of 500mm; and visual inspection.
5.3 Basic error test
The test shall be conducted on the special equipment. The height deviation of the
special equipment shall be ±2mm. During the test, the liquid level shall be changed
steadily from UP (Full 1) to DOWN (Empty 0); output value at 1, 1/2, alarming point,
and 0 shall be measured by using multim......
