HONEYWELL matters needing attention for differential pressure transmitter

Dec 01, 2020

1: Do not add voltage higher than 36V to the transmitter to cause damage to the transmitter;

2: Do not touch the diaphragm with hard objects, which will damage the isolation diaphragm;

3: The measured medium is not allowed to freeze, otherwise the isolation diaphragm of sensor element will be damaged and the transmitter will be damaged. If necessary, the temperature protection of the transmitter is necessary to prevent icing;

4: When measuring steam or other high-temperature medium, the temperature should not exceed the limit temperature of the transmitter. If the temperature is higher than the limit temperature of the transmitter, the radiator must be used;

5: When measuring steam or other high-temperature medium, the radiator should be used to connect the transmitter with the pipeline, and the pressure on the pipe should be transmitted to the transformer. When the measured medium is water vapor, a proper amount of water should be injected into the cooling pipe to prevent overheating steam from contacting the transmitter directly and damaging the sensor;

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

a. Do not leak at the connection between transmitter and heat pipe;

b. Before using, if the valve is closed, the valve should be opened very carefully and slowly to avoid direct impact of the measured medium on the sensor diaphragm, thus damaging the sensor diaphragm;

c. The pipeline must be kept unblocked, and the sediment in the pipeline will pop up and damage the sensor diaphragm;
