Small make up teach you how to choose and pressure gauge

With the development of the industry, the pressure gauge is widely used in various fields. It can intuitively show the pressure change of each working procedure link, insight into product or medium in the process conditions of formation, monitor the safety trend in the process of production. How to choose and buy a trust of pressure gauge, small make up to introduce below: pressure gauge dial diameter in order to make the operation personnel, is to be able to see the pressure value, pressure gauge dial diameter should not be too small, if the pressure gauge is installed higher or far away from the post, dial diameter should be increased. Pointer process should be smooth, no jump needle, stagnation phenomenon. Pressure gauge is not operation, limited check nails, nail should be close to the limit, and within the zero mark line. （ Visual) Pressure gauge visible parts have no obvious blemishes, scratch or damage. Pointer, installation method, pan, cover, inside the machine, joint and table cover shall comply with the requirements of customers to buy. Pressure gauges shall not have the nipple which is collapse, grinding bald and slippery tooth phenomenon; Table should maintain a transparent light, no oil, scratches. For electroplating parts, can not have product paint, such as orange stripes have obvious flaw phenomenon. Pressure gauge must be appropriate bubble bag or set of plastic bags, and put the corresponding outer. Stable pressure gauge indication is clear, long service life, the specification can be customized according to your requirements, the corresponding parameters can be customized according to your need, easy to use and each domain. Finally, please choose the appropriate range, in use process to avoid overpressure caused by pressure
