Intelligent High-Precision Monocrystalline Silicon Pressure/Absolute Pressure Transmitter HNP30-A

HNP30-A series of intelligent pressure / absolute pressure transmitter, the center of the sensing unit using the world's leading high-precision silicon pressure sensor technology and packaging technology, monocrystalline silicon pressure sensor is located in the metal body at the top, away from the media contact surface, to achieve mechanical isolation and thermal isolation; glass sintered sensor leads to achieve a high-strength electrical insulation with the metal substrate, improving the flexibility of the electronic circuit and the ability to protect against transient voltage. Transient voltage protection. The temperature change is very small, the optimum can be controlled at 0.04%/10K. In the circuit design of the microprocessor as the core and assisted by advanced digital isolation technology modular design, so that the instrument has a very high anti-interference and stability.
Using Hart protocol for communication, the instrument can be operated remotely by Hart hand manipulator or computer with Hart software installed to complete the measurement information configuration, while digital compensation technology is adopted and the transmitter is compensated by the built-in temperature sensor, which improves the measurement accuracy, reduces the temperature drift, and has the characteristics of good long-term stability and high reliability. The most humanized design of the external one-key zero function, to meet the safety requirements of hazardous occasions, the shortcut menu is convenient to operate, and can complete all the parameter settings, comprehensively improve the performance of the transmitter.
