Ordering considerations
1. Product range selection:
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;
2. Product power supply and output:
The selection of power supply range is determined according to the output specifications of the product:
Conventional 4-20mA, DC 12-30vdc power supply;
Display header, four places, one decimal place;
3. The user should understand the measurement medium characteristics of the product:
Medium specification, medium temperature, medium purity (whether containing impurities or particles, etc.);
4. Users should understand the installation environment and installation method of the product:
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;
