Discussion in the form of a pressure gauge

Generally speaking, pressure gauges are divided into diaphragm pressure gauges, bellows pressure gauges, diaphragm-type pressure gauges, and ordinary Bourdon tube pressure gauges. I had nothing to do today, so I discussed several different differences; the results from Baidu were all just copied and useless. I simply drew a diagram; please advise, experts. Additionally, diaphragm pressure gauges are generally used for measuring low pressures, and they can come with or without flanges. The pressure sensing element is a diaphragm box. The flange of diaphragm pressure gauges is non-removable; the lower end features a standard pressure gauge connector. Diaphragm pressure gauges are capable of measuring high pressure ranges. In fact, a diaphragm pressure gauge consists of a regular Bourdon tube pressure gauge along with a diaphragm that acts as a separator between the medium and the gauge’s sensing elements, with a filling fluid used to transmit pressure. The pressure-sensing element of a regular Bourdon tube pressure gauge is a Bourdon tube or diaphragm tube. 1. I want to know whether a diaphragm box pressure gauge with flanges can be disassembled
