As the name suggests, pressure gauges are essential instruments to measure pressure. Pressure gauges have become a necessary addition for industries that deal with the flow of liquids and gasses on a daily basis.
However, they are equally important when employed in medical testing equipment in hospitals to help patients combat emergencies.
Therefore, like many other process measuring instruments, there are certain aspects to keep in mind before selecting pressure switches with gauges. Unlike sensors that tend to generate an electrical signal and require to be connected to a device to make their measurement readable, pressure gauges allow pressure values to be read directly on a dial or digital display.
* Identifying Maximum System Pressure Of Your Application
Maximum system pressure determines the sensor or the spring code and is vital in preserving switch functionality and integrity. Remember that overpressure should not exceed the rated proof pressure of the switch, else the switch won't meet performance standards.
* Selection Of Pressure Gauge Material
Pressure gauge typically has two material selections that involve cabinet and process selection. The process connection includes any component of the pressure gauge that comes in direct contact with the fluid or the gas. Experts suggest that it is essential to know the media's composition while selecting pressure switch testing equipment. Material incompatibility can cause issues like corrosion, gauge failure, and increased safety risks.
*Environmental Conditions
While working under extreme ambient temperatures, pressure gauges are required to be isolated. A remote mount gauge with a diaphragm seal and flexible capillary line can be used in such a case. Experts also suggest using snubber in areas where pressure spikes and pulsations are commonly seen. This is why a pressure gauge with stainless steel, plastic, or brass case is suitable for outdoor use.
* IP Rating
An IP rating is most commonly seen in electronics and electrical devices today like smartphones, speakers, etc. A pressure gauge also entails an IP rating. An IP rating is the degree of protection for the pressure gauge against foreign particles, including dust, moisture, liquids, and accidental contacts. In specific circumstances, pressure gauges require heavy operating in a harsh environment, making their IP rating a critical phenomenon.
Note
A pressure gauge is chosen accordingly with its measurement range. Therefore, the market is loaded with analog dial pressure gauges where their operating machine must be between 1/3 and 2/3 of the range.
Conclusion
Medical testing equipment is an essential addition to every medical facility. Therefore, the proper selection of pressure switches and gauges is necessary. Patient life is dependent on efficient delivery of crucial gasses, and any amount of irregularity can result in life or death situations. Hence, always rely on experts when buying these equipment.
