2、 Specification and model
5、 Installation method
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 power supply of pressure core is constant voltage
source (3-10vdc);
The core output is differential bridge output;
The output signal is about (0.6-1.5) MV / V
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;
