1. Do not add a voltage higher than 36V to the transmitter, causing damage to the transmitter;

2. Do not touch the diaphragm with hard objects, resulting in damage to the isolation diaphragm;

3, the measured medium is not allowed to freeze, otherwise it will damage the sensor element isolation diaphragm, resulting in damage to the transmitter, if necessary, the transmitter temperature protection, to prevent freezing;

4. When measuring steam or other high-temperature media, the temperature should not exceed the * * * limit temperature when the transmitter is used, and a heat dissipation device must be used when the temperature is higher than the * * * limit temperature used by the transmitter;

5. When measuring steam or other high temperature media, a heat pipe should be used to connect the transmitter and the pipeline, and the pressure on the pipeline should be used to transmit to the transformer. When the measured medium is water vapor, an appropriate amount of water should be injected into the heat pipe to prevent the superheated steam from directly contacting the transmitter and damaging the sensor;

6. In the process of pressure transmission, the following points should be paid attention,

A, transmitter and heat pipe connection, do not leak;

B. Before starting to use, if the valve is closed, when using it, the valve should be opened very carefully and slowly to prevent the measured medium from directly impacting the sensor diaphragm and damaging the sensor diaphragm;

C, the pipeline must be kept unblocked, the sediment in the pipeline will pop up and damage the sensor diaphragm

All, in the use of intelligent pressure transmitter must keep in mind the above points, so as not to cause unnecessary losses.
