How to Select a Pressure Transmitter: These 5 Parameters Matter Most
Pressure transmitters are among the most widely used measuring instruments in industrial applications. Correct selection directly affects measurement accuracy and service life.
1. Range Selection
Select a range of 1.2 to 1.5 times the actual maximum pressure to avoid long-term full-scale operation.
2. Accuracy Class
Class 0.5 is suitable for general process monitoring, while class 0.1 or higher is recommended for precision metering.
3. Media Compatibility
Choose the appropriate diaphragm material according to the corrosiveness of the measured medium, such as 316L, Hastelloy or tantalum.
4. Process Connection
The connection must match the on-site piping interface. Common specifications include M20x1.5, G1/2 and NPT.
5. Ingress Protection
For outdoor or humid environments, select products rated IP67 or higher.
