Some Precautions About Pressure Transmitter Installation

- Oct 19, 2017 -

1, the design and installation should be considered at the bottom of the tank to take the pressure hole as low as possible to eliminate the temperature changes caused by the error, if necessary, the introduction of temperature compensation.

2, the second table as far as possible using smart table, can easily change the range, to achieve temperature compensation.

3, the pressure transmitter in the measurement of steam or other high-temperature medium, the temperature should not exceed the limit temperature used by the transmitter, higher than the limit temperature used by the transmitter must use the cooling device.

4, the measured medium is not allowed to freeze, or will damage the sensor components to isolate the diaphragm, resulting in damage to the transmitter, if necessary, the need for pressure transmitter temperature protection to prevent freezing.

5, the pressure transmitter can not be used in more than 36V voltage added to the transmitter, resulting in damage to the transmitter, can not touch the membrane with a hard object, resulting in damage to the diaphragm.

6, the measurement of steam or other high-temperature medium, you should use the heat pipe, so that the temperature transmitter and pipe together, and the use of pressure on the pipeline to the transformer. When the measured medium is water vapor, the heat pipe to be injected with the right amount of water to prevent direct contact with the pressure transmitter, damage to the sensor.
