Single Flange Capillary Remote Diaphragm Seal Pressure Transmitter
Product Overview:
This remote diaphragm seal pressure transmitter (also known as single flange capillary pressure transmitter)
is designed for pressure measurement in challenging industrial conditions.
It uses a capillary tube filled with a special fluid to transmit pressure from the remote diaphragm seal
(mounted on the process flange) to the pressure sensor, isolating the transmitter from high temperatures,
corrosive media, viscous fluids, or materials prone to solidification.
The unit provides a standard 4-20mA analog output (with optional HART/Modbus communication) and
features a digital display for on-site reading.
With explosion-proof certification and high-grade stainless steel construction, it ensures reliable, long-term
performance in harsh environments.
Typical Applications:
High-temperature and high-pressure process pipelines
Viscous, corrosive, or solidifying media (oils, slurries, resins)
Vacuum systems where direct sensor contact is not desired
Petrochemical, chemical, and refinery processes
Pharmaceutical and food & beverage production
Power plants and energy utilities
Tank level measurement in storage vessels
