Digital Oil Pressure Gauge 1/4 NPT Stainless Steel Short - Circuit Protection
The selection of pressure gauges should be based on the production process requirements, and specific analysis should be made for specific conditions. Under the premise of meeting the process requirements, comprehensive and comprehensive consideration should be made on the principle of economy. Generally, the following issues should be considered:
The choice of type
The choice of instrument type must meet the requirements of process production. For example, do you need remote transmission, automatic recording or alarming; the properties of the measured medium (such as the temperature of the measured medium, viscosity, corrosion, degree of contamination, whether it is flammable or explosive, etc.), or whether special requirements are placed on the instrument or not? Environmental conditions (such as humidity, temperature, magnetic field strength, vibration, etc.) requirements on the type of instrument. Therefore, the correct selection of instrument type according to the process requirements is an important prerequisite for the normal operation of the instrument and safe production.
For example, spring tubes for common pressure gauges use copper alloys (high-pressure alloy steels), and ammonia pressure gauge spring tube materials use carbon steel (or stainless steel), which does not allow copper alloys. Because ammonia and copper react chemically and explode, ordinary pressure gauges cannot be used for ammonia pressure measurements.
Oxygen pressure gauges and ordinary pressure gauges can be identical in structure and material, except that oxygen pressure gauges must be banned from oil. Because the oil into the human oxygen system can cause explosions. Oxygen pressure gauges used in the calibration can not use oil as working medium like ordinary pressure gauges, and oxygen pressure gauges should strictly avoid contact with oil during storage. If it is necessary to measure the oxygen pressure using an existing oil pressure gauge, it must be cleaned with carbon tetrachloride repeatedly before use and carefully checked until there is no oil.
