5、Installation method

In order to achieve the best effect of product accuracy, life, stability and other functions, the range selection of the product is calculated by referring to the following formula:
Range = x (1.2-1.5) times of the maximum system pressure;
The actual measuring pressure range of the product should be 15% - 80% of the range;

The signal output specification depends on the requirements of the back-end acquisition equipment;
Common are: control and display instrument, PLC acquisition and input module, MCU acquisition card, PC serial port, etc
If the back-end acquisition equipment is determined according to the output specification of the product, it is recommended to use the general two-wire system 4-20mA;

Medium specification, medium temperature, medium purity (whether containing impurities or particles, etc.);

Indoor or outdoor installation;
Ambient temperature;
Required sealing level;
Vibration range of equipment;
Installation method: thread, flange, special structure;
Whether the installation space meets the overall dimension of the product;
