GNG/LPG high-pressure sensor
This series of products uses a silicon piezoresistive sensor chip with good consistency and strong stability, and is made through a stainless steel diaphragm isolation and oil-filling process. It has fast response time, low signal noise, strong anti-interference ability, high reliability, shortcomings, etc. Advantages: It is very suitable for pressure measurement in wall-mounted boilers, water pumps, intelligent fire protection, variable frequency water supply, air compressors and other fields.
Standard voltage signal (with NTC), soldered silicone wire/ribbon cable.

Matters needing attention
The measuring medium cannot be frozen;
During installation, avoid scratching the O-ring seal;
During installation, the direction of the pressure inlet should face downwards as much as possible to prevent impurities from settling in the medium and blocking the pressure inlet;
The back pressure chamber cannot be blocked;
The back pressure chamber should not have moisture (polymer plugs or breathable films can be used);
The power supply needs to be filtered to prevent damage to this product caused by instantaneous high currents;
If there are obvious surges in the product's operating environment, it is necessary to add protective circuits such as TVS tubes;
Avoid falling, hitting, and puncturing hard objects;
Avoid product exposure to water and strictly prohibit water immersion;
It is strictly prohibited to disassemble the casing to avoid product damage.
Disclaimer
Use of media beyond regulations;
Exceeding the specified power supply voltage for use;
Use beyond the specified temperature range;
Use beyond the specified pressure range;
Severe deformation or damage to the isolation membrane caused by improper operation;
Force majeure, such as product damage caused by lightning strikes, etc;
Other product damage caused by failure to use in accordance with the requirements of this specification.
Note: The accuracy of a product refers to the error rate between the theoretical output value (calculated according to the output formula) and the actual measured value.
That is, accuracy=(measured value - theoretical value)/net output
Net output: 4.5-0.5=4
