For capillary pressure transmitters, is it necessary to pay attention to the installation location?
Thread Content
I just purchased a unit with a capillary pressure transmitter. Can it be installed and used right away after purchase? Is it necessary to pay attention to the height of the flange and the gauge head? Does it have an impact if the header height and flange height are not consistent? If there is an impact, how can it be resolved? Thank you!
One should pay attention to those with a low pressure range; generally, capillary pressure transmitters are not very long, with a deviation of at most 1–2 kPa. Those with low requirements can be ignored; for those with high requirements, zero-point calibration can be used to eliminate the issue. zero trim
There is basically no impact; just perform zero-point calibration after installation
The header has nothing to do with the flange height; just reset the zero position after installation
It’s not a big problem; calibrate the zero point after installation
The installation position of the header has no impact; after installation, negative migration is required, and a fixing bracket should be used for the capillary.
Generally, there is no impact. In negative pressure conditions, the transmitter must be placed at least 600 mm below the flange; installing it above the flange may damage the diaphragm
Since it is a pressure-sensing transmitter, it is best to have it at the same level as the flange or below it, allowing for direct installation; simply perform a zero-point calibration before use.
After installation, calibrate the 0 point; the installation position of the gauge head does not matter – it can be placed wherever it is easy to view and maintain.
