Has one of following cases, pressure gauge is best to stop using!

Pressure gauge is used for measuring less than or greater than the atmospheric pressure, used for measuring fluid flow ( Gas, liquid) Pressure gauges, has extremely extensive application in industry. But any instrument in the long run will be failure, now just repaired. But in some cases, these problems is beyond repair, this instrument can no longer in use. Small make up take the stop using the pressure gauge, use pressure gauge to you some help. 1. Limited check pin gauge, when there is no pressure, can't return to the hands nail limit; Too limit pin gauge, in the absence of pressure and guidance from the bit values exceed the permissible error of pressure gauge; 2. Dial is sealed to the glass broken or dial to the degree of fuzzy; 3. Seal damage or cross check validity; 4. Spring in the table loose tube leakage or pressure gauge pointer; 5. Other defects affecting the pressure gauge accurate instructions. When you use pressure gauges have these problems? If found a similar problem, better to keep the pressure gauge to stop working, looking for professional personnel to repair it. If really can't repair, can only to buy a pressure gauge.
