The G-series differential pressure transmitters adopt the world's leading high-precision silicon pressure and differential pressure sensor technologies and packaging processes in their central sensing units. The monocrystalline silicon pressure and differential pressure sensors are located at the top of the metal body, far from the medium contact surface, achieving mechanical and thermal isolation. The sensor leads sintered integrally with glass realize high-strength electrical insulation from the metal substrate, improving the flexibility of the electronic circuit and the ability to protect against transient voltages.The circuit design employs a modular approach centered around a microprocessor and supplemented by advanced digital isolation technology, endowing the instrument with exceptional anti-interference capabilities and stability. It utilizes the HART protocol for communication and remote operation.
