Pressure Transmitter Installation and Usage Considerations - Focus on Microfluidic Control Technology

Pressure transmitter installation and use precautions

(1) The pressure transmitter should be installed perpendicular to the horizontal plane;

(2) The pressure transmitter measurement point is at the same level as the pressure transmitter installation, otherwise the correction of the additional height error is considered;

(3) To ensure the sealing performance, there should be no leakage, especially flammable and explosive gas medium and toxic and harmful medium.

(4) The distance between the installation position of the pressure transmitter and the measuring point should be as short as possible to avoid delaying the indication; the pressure transmitter should be added with additional equipment when used in the following cases, but no additional error should be generated, otherwise the correction should be considered.

(1) In order to ensure that the pressure transmitter is not affected by the measured media or the viscosity is too large and crystallized, an isolation device shall be installed;

(2) In order to ensure that the pressure transmitter is not affected by the sharp change of the measured infrared carbon sulfur analyzer medium or the pulsating pressure, a buffer is added. Especially when the pressure increases sharply and the pressure drops sharply, the pressure pressure transmitter is most likely to be damaged and scrapped, and even the spring tube cracks and leakage occurs.

(3) In order to ensure that the pressure transmitter is not affected by vibration, the pressure pressure transmitter shall be equipped with vibration-reducing device and fixing device;

(4) In order to ensure that the pressure transmitter is not affected by the high temperature of the measured medium, an elbow device full of liquid should be installed;

(5) special special pressure transmitter, it is forbidden to use, and it is forbidden to carry out measurement on the device without special and reliable, and it is forbidden to use common pressure gauge as pressure measurement of special medium;

(6) For newly purchased pressure sensing pressure transmitters, measurement verification must be performed before installation and use to prevent vibration, damage, or other factors from destroying the accuracy of pressure transmitters during transit.
