Single Flange Pressure Transmitter
Page Feature Highlights
· Exceptionally high accuracy, repeatability, vibration resistance, and wide measurement range
· Anti-electromagnetic interference capability
· Suitable for pressure measurement in pressurized vessels
· Equipped with on-site programming and display functions
Product Overview
The Single Flange Diaphragm Remote Pressure Transmitter is an ultra-high-performance hydrostatic/differential pressure level gauge developed with advanced single-crystal silicon sensor packaging technology. The single-crystal silicon pressure sensor is positioned at the top of the metal body and connected via a capillary tube, isolating it from direct medium contact. This enables mechanical and thermal isolation. Widely used in mechanical engineering and automation control systems, it can interface with readouts, recorders, computers, PLCs, or alarms.
