Description:

HEAT AND COLD RESISTANCE: placed in the environment of 803 or -203 for 72h, no abnormality after 1-2h recovery to normal temperature, no cracks, relaxation, expansion, deformation and other phenomena in the parts.. MOISTURE RESISTANCE: After placing for 72h at 603 and relative humidity of 90%95%RH, the insulation resistance is above 1M.. INSULATION RESISTANCE: The insulation resistance between the Hall sensor lead and the valve body is more than 100M. (DC 500V).. INSULATION TOLERANCE: Hall sensor lead and valve body are pressurized by AC600V (50/60Hz) for 1 second without insulation abnormality.. IMPACT RESISTANCE: The product is well packaged, and there is no abnormality in the X, Y and Z directions from a height of 50cm to the concrete surfaces, and the accuracy changes within 10%..
