JC-G Series
JIECHUANG
High-Temperature Single Flange Pressure Transmitter
This high-temperature single flange pressure transmitter is specially designed for pressure and liquid level measurement in high-temperature industrial environments.
It adopts a direct flange connection structure with a built-in high-temperature diaphragm and heat dissipation component, which can withstand high-temperature media directly without the need for capillary extension.
The transmitter converts pressure signals into standard 4-20mA DC output (with optional HART digital communication), and features a high-accuracy sensor and explosion-proof housing.
With its compact structure, stable performance and excellent high-temperature resistance, it is widely used in various high-temperature, corrosive or viscous process conditions.
● Oil/Petrochemical/Chemical Industries:
Paired with throttling devices to provide precise flow measurement and control.
Accurate measurement of pressure and liquid level in pipelines and storage tanks.
● Power Plants/City Gas/Other Public Utilities:
Suitable for environments requiring high stability and high accuracy in pressure, flow, and liquid level measurements.
● Pulp and Paper Industry:
Ideal for measuring pressure, flow, and liquid levels in environments that require resistance to chemical and corrosive liquids.
● Steel/Non-Ferrous Metals/Ceramics:
Suitable for measuring furnace pressure and negative pressure in applications demanding high stability and high accuracy.
● Machinery Equipment/Shipbuilding:
Used in environments requiring stable measurement under strict control of pressure, flow, and liquid level indicators.
