Pressure Gauge Calibration
Pressure gauges are one of the most commonly used and relied upon instruments in today’s manufacturing environment. However, due to their great numbers, there is often a lack attention given to calibration intervals and therefore reliability can become compromised. Due to these oversights, it is not uncommon in to see many pressure gauges out of calibration, tagged out of service or even not functional at all. This can become a real problem because if a plant is operating with a failed or out of calibration pressure gauge in a critical process, the quality of the product being produced or more importantly the safety of the plant may be at risk. Therefore, one goal of good process control is to establish a procedure to set and ensure pressure gauge calibration intervals are maintained. There are many different types of pressure gauges used in almost every manufacturing environment imaginable. PCS can calibrate these gauges either in your facility or in our controlled calibration laboratory. The major types of commonly used pressure gauges used are:
Air or Pneumatic Pressure Gauge Calibration
Air pressure or pneumatic gauges measure the amount of air needed to maintain the optimum use of the object containing this gas. A common container of air is a tire. Using an air pressure gauge ensures the correct amount of air fills the tire for optimum performance. Too little air in a tire eventually makes it flatten while too much air makes it wear unevenly or even explode.
Hydraulic Pressure Gauge Calibration
Hydraulic pressure gauges are used for measuring pressure in environments that are subject to mechanical vibrations or in applications where pressure pulses may take place. They are ideal for precise measurement and recording of hydraulic tool pressures. Some gauges may be liquid or glycerin filled so they are able to give a perfect vibration display and smooth pointer movement, even in conditions of heavy load and strong vibration. The lubricating effect of the glycerin also provides protection to the system against mechanical wear. The pressure gauges are designed and manufactured keeping in mind increased reliability and extended service life. Digital pressure gauges have become popular.
Differential Pressure Gauge Calibration
A Differential pressure gauge indicates the difference in pressure between two points. These gauges contain two entrance ports with each connected to one of the monitored pressure capacities. Using this type of pressure gauge allows one the ability to read the pressure difference between two points with one gauge rather than having to check two pressure gauges and calculate the difference. These gauges are particularly useful for checking the filter conditions HVAC or dust collection systems thus preventing the need to check the filters manually.
Digital Pressure Gauge Calibration
Digital pressure gauges convert pneumatic, hydraulic, or differential pressure into signals that read out in numerical displays. Digital pressure gauges are becoming more and more popular due to their smaller size and greater accuracy and readability. The digital pressure gauge can be use in almost any application that a conventional gauge is being used. As the prices of these gauges continue to decline, the use of the digital pressure gauge will inevitability increase in the years to come.
