Overview of Flush Diaphragm Pressure Transmitter
A flush diaphragm pressure transmitter is specially designed for measuring pressure in challenging applications, such as those involving highly viscous or solid-laden fluids. Unlike traditional pressure transmitters, flush diaphragm transmitters feature a diaphragm that sits flush with the device's front, preventing debris buildup and contamination.
Main Features
- Precise & accurate
- Flush Diaphragm process connection
- Wide range compatibility
- Fully welded design
