GH3351 Monocrystal Silicon Differential Pressure Transmitter

Introduction

The GH3351 series of intelligent pressure/differential pressure transmiters feature a globally leading high-precision silicon pressure/diferential pressure sensor technology and packaging process, The single-crvstal siliconpressure/differential pressure sensor is located at the top of the metal body, far away from the medium contactsurface, achieving, mechanical and thermal isolation. The glass-sintered integrated sensor lead achieveshigh-strength electrical insulation with the metal substrate, enhancing the flexibility and transient voltage protection of the electronic circuitry. With platinum-level accuracy reaching ±0.05%, it can withstand a maximumone-way overpressure of 25MPa., Boasting excellent static pressure performance, the static pressure error can beoptimally controlled within t0.05%/10MPa, with minimal temperature impact variations, optimally controllableat ±0.04%/10K.

In terms of circuit design, a modular design centered on a microprocessor and assisted by advanced digitaisolation technology is adopted, ensuring the instrument's excellent anti-interference and stability. Communicaton is achieved using the Hart protocol, allowing remote operation through a Hart handheld device or a computer with Hart software to complete measurement information configuration. eanwhile, digital compensationtechnology is employed, and the transmitter is compensated using a built-in temperature sensor, improvingmeasurement accuracy, reducing temperature drift, and possessing long-term stability and high reliability.The most user-friendly design includes infrared wireless settings and a one-button reset function, meeting thesafety operation reguirements in hazardous environments, it provides convenient and guick menu operationsand can complete all parameter settings, comprehensively enhancing the performance of the transmitter.
