GPX700 Series Flange Pressure Transmitter
Features
●Flush membrane structure
●Isolation explosion-proof
●Designed for pressure vessels, tanks and other special environment
Introduction
The GPX700 series flange pressure transmitters are designed with high-reliability core components, such as silicon piezoresistive sensors, ceramic capacitors, sapphire, and sputtering film pressure sensors, selected based on the specific needs of various industries. These transmitters undergo temperature compensation, digital circuit correction, and signal conditioning to provide accurate industrial standard outputs. Each product is rigorously tested through comprehensive design, component selection, process verification, cyclic loading, aging, and environmental simulation to ensure long-term stability and reliability.
Application
The GPX700 series flange pressure transmitters are versatile and highly reliable instruments designed for a wide range of pressure measurement applications across various industries. They are particularly well-suited for demanding environments, such as those found in coal mining, oil and gas extraction, chemical processing, civil explosion safety, environmental monitoring, healthcare, water management, and maritime sectors.
