Ordering considerations

Precautions for ordering PT500-560 RS485 digital pressure transmitter
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:
Power supply range 9-30vdc:
Low power RS485-rtu output;
Please understand the communication protocol first;

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;
Pressure seal: taper seal, face seal, arc seal, spherical seal;
Whether the installation space meets the overall dimension of the product;

Precautions for use

Precautions for PT500-560 RS485 digital pressure transmitter
Product power supply 24vdc (range: 9-30vdc);
It is strictly prohibited to use hard objects (such as screwdriver, finger, iron nail, etc.) to make the pressure core body under pressure measurement output;
The power and signal wires shall be correctly wired according to the specifications of the ordered products;
When the product is installed, the stressed part is "process connection hexagon wrench position", and the wrench specification corresponds to hexagon;
It is strictly prohibited that the medium temperature, pressure range and excitation voltage of the tested system exceed the rated use range of the transmitter;
Pay attention to protect the outgoing cable of the transmitter. When the span is too large on site, it is recommended to use metal pipe for protection or overhead;
The pressure transmitter is a precision measuring instrument, do not impose impact or smash to avoid damaging the core;
The product is installed in a ventilated, dry and non corrosive environment, and installed in the open with protective devices to avoid direct sunlight;
