Can a cartridge-type local pressure gauge be used in a atmospheric-pressure system?

Can a clamp-type local pressure gauge be used in a atmospheric-pressure system, and is it easy to remove? Since both sets of equipment use the same pressure gauge, it is possible to remove the gauge from one device and use it on the other when that device is not in use
Doesn’t the pressure gauge need to be calibrated? Theoretically, it is possible, but real-world maintenance conditions need to be taken into account.
It’s so troublesome to keep taking it apart like this; it’s better to just install two pressure gauges – and the cost isn’t high at all
It can be used, but the card-type design makes it easy to leak due to frequent disassembly:lol
A bayonet-type local pressure gauge can be used, as it is easy to remove and replace, just like ordinary pressure gauges; however, attention should be paid to the quality of the bayonet and the connection tubes
There’s no need for that; it’s not much money either. Just buy another one
The pressure gauge itself already has threads, so a threaded connector can be used; the other end is connected to the gauge tube using a clamp, and a clamp is certainly an option for this purpose.
Pressure measuring instruments with bayonet connections are widely used in the food industry, pharmaceutical industry, and cosmetics industry. It’s very widespread. The reason why card-type connectors are commonly used in these industries is that residues such as those on the diaphragm and in areas where installation is difficult, along with fermentation bacteria, need to be removed manually on a timely basis. Secondly, when high-temperature steam is used to disinfect tanks and pipelines, if the meters are not removed and replaced with covers, zero drift of the meters as well as damage to them due to the heat are common occurrences. The allowable pressure for bayonet connections is usually < 2 MPa.
