Issues with removing the pressure gauge housing

Local pressure gauge? Use a wrench, a large wrench, **wrench

A local pressure gauge? That thing can’t be removed unless it’s taken apart destructively. If it’s the front and back covers of the transmitter and they can’t be removed, that’s problematic. What I do is disconnect the wires at the terminals to cut off the power, then use a hand saw to cut around the edges of the covers; after doing this, the transmitter is essentially ruined and its components can only be taken apart as spare parts. It is recommended to apply a layer of Vaseline or butter to the threads of the transmitter’s front and rear covers before screwing them on, especially those that are not used frequently.

I am a manufacturer of pressure gauges. If a pressure gauge loses accuracy over time or becomes damaged, you can sell it to me or exchange it for a new one. If you decide to disassemble it, you need to use a special clamping device; afterwards, you can use a screwdriver to remove it. 15255081999

Local pressure gauge? Why are you taking that thing apart?

Why are you taking it apart? It can’t be fixed even after being taken apart

Hehe. . . Who said this pressure gauge is useless after being taken apart? Speaking of which, a pressure gauge has three metal components: the Bourdon tube, which is usually made of yellow metal; however, many manufacturers these days use stainless steel for it, with more honest ones using 316 stainless steel, while unscrupulous sellers use ordinary steel instead. The pointer dial of the pressure gauge is made of aluminum alloy. Gauge case, made of iron or stainless steel. Although scrap metal is now cheaper, copper still costs around 5 to 6 yuan per jin, aluminum lids cost 3 yuan per jin, scrap iron costs 0.4 yuan per jin, and stainless steel costs 0.5 yuan per jin; 316 stainless steel is a bit more expensive at over 2 yuan per jin due to its nickel content. Hehe. . . The manufacturers of pressure gauges back in the day were honest; three pressure gauge elements weighed one jin. These days, due to the presence of unscrupulous merchants, it takes 5 or 6 pressure gauge elements to reach one jin in weight. But little by little, using about ten to eight jin per month is enough to use for rubbing everywhere, hehe. . . . I became successful by taking this exam.

There are many pressure gauges whose back covers lack fixing screws; they can only be removed from the covering section. If removal is difficult, use diagonal pliers to cut through it. However, before removing them, check what material the exposed connections of the pressure gauge are made of – if it’s copper, it can still be repaired; if it’s stainless steel, just throw it in the trash. As for those filled with oil, discard them outright, as the cost of cleaning them off your hands isn’t even worth the price of dish soap. If you want to give it a try, there’s no need to worry about using a watch screwdriver to remove the hands; just find two screwdrivers with thin tips and place them at each end of the shaft, then apply force upward – and it’s done easily. If you want to break it, just use pliers to pull it outward and it will come off. Hehe. . . If you want to ask who I am, call me Lei Feng.

It took a lot of effort to turn it open, but it was useless anyway; just sell it as scrap
