When is a single-flange pressure transmitter equipped with a capillary tube used?
Thread Content
Some single-flange pressure transmitters can be installed directly on pipes or equipment, while others require a capillary tube. I would like to know when a capillary tube is necessary ? ? ? ?
It needs to be positioned at a distance; it vibrates, which facilitates installation. For observation, use a capillary!
Capillaries are used when it is not possible to use pressure transfer tubes to connect the medium to the transmitter, due to factors such as contamination in the medium or high viscosity
Reply 1# sdqust agrees with what was said on the third floor; additionally, it is also necessary to take into account the corrosiveness of the medium
Generally, a single-flange type is installed as an integral part of the equipment, unless it needs to be disconnected for ease of maintenance.
It’s not asking why a single-flange design is used; it’s asking about the principles for choosing whether to use a capillary with a single flange. Please don’t get it wrong
For media that tend to crystallize or are at high temperatures, it is possible to consider using a capillary to draw them out
I think it’s mainly to ensure reliability and the impact of vibration on the instruments.
1. Capillary remote leading is only possible when there is diaphragm sealing. 2. Under normal circumstances, it can be installed in a short distance without the need for long runs. 3. For the purpose of easy maintenance or operation, when it is necessary to place the display header at a position away from the diaphragm seal, capillaries are used.
It is mainly to ensure reliability and the impact of vibration on the instruments. Single-flange level transmitters include flat-flange and flange with insertion tube types; both utilize the gravity of the medium being measured to determine the liquid level. Single-flange level transmitters are suitable for media with high viscosity and tendency to crystallize, and are generally used in the installation of open containers or equipment.
