Pressure gauges used for measuring condition of a fluid (liquid or gas). They are still useful in many applications, and developments can extend their capabilities. Pressure gauges is still a great way to visually show what is happening in the process.
Traditional gauges have some drawbacks that are considered in the selection process. Gauges operate delicate mechanisms with springs and gears, making them vulnerable to shock and damage.
Some of the considerations for selecting a pressure gauge:
- Material of construction:
Some of the cheapest devices are mostly brass made, industrial-grade gauges are usually made of stainless steel or any other durable materials.
Cases are armored with rubber covers and beefed-up mechanisms to survive in tough and harsh environments, but these options are more in cost. Some of the models are designed for environments where pipes vibrate or in the case of moving equipments.
- Inlet configurations:
Smaller and cheaper devices may have inlet configurations of ¼-inch NPT. Male-threaded inlet, usually of ½-inch national pipe thread (NPT).
Some of the improvements that can be done based on design are digital gauges and electronic gauges.
