Ordering considerations

Precautions for ordering PT500-706P products
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 / 0-20mA, 0-5V / 10V output, DC 12-30vdc power supply;
General rs485-rtu output, DC 12-30vdc power supply;
0.5-4.5vdc output, DC 5VDC;
Low power output power supply range: 3.6vdc (3-5vdc)

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:
Whether the flameproof protection level can meet the requirements of field conditions;
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;

Precautions for use

Different product signal output specifications correspond to different power supply range requirements;
It is strictly prohibited to use hard objects (such as screwdriver, finger, iron nail, etc.) to make the pressure diaphragm output under pressure measurement;
