Pressure Gauge

Pressure gauge specifications include crucial details like the scale range to measure pressure (e.g., 0–100 bar), the accuracy class which indicates the maximum deviation from the reading (e.g., ±1% of full scale), the nominal size (dial diameter in mm), the connection type and size (e.g., G1/2" NPT), the case material (e.g., stainless steel), and the pressure element material (e.g., Bourdon tube) to ensure compatibility with the process media. Other factors include the window material, ingress protection (IP) rating, process fluid temperature, and over-range protection.
