1. Product range selection:
In order to achieve the best effect of product precision, life, stability and other functions, the range selection of the product is calculated according 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 measuring range;
2. Product power supply and output:
Power supply range: DC 12-30vdc;
The switch output of the relay has load capacity, and the driving current is less than the rated current;
Whether 4-20mA transmission output is required;
3. To understand the measurement medium characteristics of the product:
Medium specification, medium temperature, medium purity (whether it contains impurities or particles, etc.);
4. Users should understand the product installation environment and installation method:
Indoor or outdoor installation;
Ambient temperature;
Required sealing class;
Vibration range of equipment;
Installation mode: thread, flange and special structure;
Whether the installation space meets the overall dimensions of the product;
