Attentions
1. Please be sure the pressure sensor' construction material is compatible with
measuring media.
2. please pay attention to the normal usage conditions of this product:
Power Supply: ≤2.0mADC or ≤10VDC.
Working Temp/ Storage Temp Range: -40℃~ 125℃.
3. The pressure sensor should be mounted as SUSPEMSION mode according to
the suggested installation dimension. Please pressurize it slowly and be sure the
measured pressure should not exceed the overpressure of the sensor; Normally, the
measured pressure should be within the pressure measurement range;
4. Please be sure it is static-free for ground equipment and personnel when
assembling and operating. The electrical contact pads are protected against ESD up
to 4 kV HBM (human body model).
5. Please do not press the diaphragm with sharp things or figures. When
assembling the sensor, please clean up the scrap iron and other remains in the
installation hole to avoid any damages on the sealing ring and diaphragm;
6. Please do not press the compensated board and do not contact it with any

conductive items to avoid any possible damages. And also please do not pull or
bend the pins;
7. Please pay attention to the pressure measurement range, and don't act large
pressure over FS for a long time. If the pressure exceeds the overpressure, the
sensor may be destroyed;
8. When assembling the sensor, please apply a little vacuum grease around the
"O" ring. If the media is oxygen, please do not apply any lubrication;
9. During application, please note the high and low sides of the differential
sensor. They are marked "H" and "L" on the body separately. Make sure the
pressure on the high side should be higher than that of the low side.
10. We recommend you operate differential pressure sensor with 3-manifold
valve together.
11. Please be sure the wet and corrosive media shall not go into the electric
connection part. Please keep the breath tube (only Gauge Type sensor) connect
with atmosphere
12. For pin electric connection, the sensor pins could be cut off, but the
remaining length shall be ≥5mm and welding time shall be ≤5s. The pins
could not be heated for a long time.
