3.Environmental test
No. Test items Test condition Standard
1 High temp storage test 144 hours at + 85 ºC After the test and place in + 25 ºC (room temp) for 24 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value 
2 Low temp storage test 144 hours at - 40 ºC
3 High temp and high humidity storage test 144 hours at + 65 ºC and 85 ± 5% RH
4 Thermal shock test Parallel 3.9k Ω resistor at both ends of the probe, keep the temp at - 40 ± 5 ºC for 0.5h, and increase the temp to 85 ± 5 ºC within 5 minutes and keep for 0.5h.100 cycles. After the test and place in + 25 ºC (room temp) for 24 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value 
5 Vibration test Products bear the vibration with frequency 10-55hz, amplitude 1.5mm,and sweep rate 1oct / min, from X, Y and Z directions for each 2 hours respectively After the test and place in + 25 ºC (room temp) for 4 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value 
6 Monomer drop test 15 free fall tests carried out from 100 ± 10cm height to 50mm thick wooden floor After the test and place in + 25 ºC (room temp) for 4 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value
7 Strength test of outlet Apply 9.8N pulling force between shell and wire for 30 seconds The wire is not loose or falling off, the product function is normal, and the wire is not damaged
8 Protection level Place the probe in 15cm deep water and soak for 24 hours Take out the capasual from the water and install it on the test board to measure the distance. The probe works normally without long sound.
9 High and low temp characteristic test Keep the temp at -40ºC for 2h,increase to 25ºC and keep for 2h,increase to 85ºC and keep for 2h.  After the test and place in + 25 ºC (room temp) for 2 hours, the sensitivity and residual vibration change shall not exceed 30% compared with the initial value
10 High and low temp working test Under high temp 85 ºC, low temp - 40 ºC, working voltage 140 Vp-p, pulse number 20, continuous working 48 hours Probe works normally (sensitivity and residual vibration are within normal range)

5.Precautions
1. Please confirm with us which industry will be used before purchasing for selection.
2. In order to prevent the sensor from failure, working failure or performance degradation, the anti failure
   function shall be added to the product design, and the product shall not be used under the following or
   similar conditions.
   (a) strong shock or vibration
   (b) prolonged exposure to high temperature and humidity;
   (c)In corrosive gas or sea breeze
   (d)Exposure to dissolved organic matter
   (e)Dusty environment;
   (f)Over allowable input voltage
