Pressure transmitters are the best-selling products in the industry in recent years. The key to good sales lies in the high density, good quality and performance of the products. However, there is a certain amount of knowledge in operation and installation in use. Installing the pressure transmitter is the beginning of all work. You say it. The following editor will share with you the precautions for installing the pressure transmitter. Let's stop and take a look ...
1. When measuring steam or other high-temperature media, a heat pipe should be used, so that the transmitter and the pipe are connected together, and the pressure on the pipe is used to transfer to the transformer. When the measured medium is water vapor, the heat pipe An appropriate amount of water should be injected to prevent the superheated steam from directly contacting the pressure transmitter and damaging the sensor.
2. When designing and installing, the pressure tapping hole at the bottom of the oil tank should be considered as low as possible to eliminate errors caused by temperature changes, and temperature compensation should be introduced if necessary. The installation of pressure transmitters is also a subject, as described above It is the problem that needs attention to the installation of the pressure transmitter. Only when the pressure transmitter is installed can it fully exert its functions and meet the requirements of measurement accuracy.
3. When the pressure transmitter measures steam or other high-temperature media, its temperature should not exceed the limit temperature used by the transmitter, and a heat dissipation device must be used above the limit temperature used by the transmitter.
4. The measured medium is not allowed to freeze, otherwise it will damage the isolation diaphragm of the sensor element, causing damage to the transmitter, and if necessary, temperature protection of the pressure transmitter is required to prevent freezing.
5. The pressure transmitter must not be used when the voltage higher than 36V is applied to the transmitter, which will cause damage to the transmitter, or touch the diaphragm with a hard object, causing damage to the isolation diaphragm.
