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

HNP30-B series intelligent pressure / differential pressure transmitter, the center of the sensing unit using the world's leading high-precision silicon pressure, differential pressure sensor technology and packaging technology, monocrystalline silicon pressure, differential 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 to improve the flexibility and ability to withstand transient voltage protection of electronic circuits. Flexibility of the electronic circuit and the ability to withstand transient voltage protection. Platinum level accuracy of 0.05%, unidirectional overpressure up to 25MPa, excellent static pressure performance, static pressure error can be optimally controlled within 0.05%/10MPa, the temperature effect of the 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, can be operated remotely by Hart hand manipulator or computer installed with Hart software to complete the measurement information configuration, and digital compensation technology, and through the built-in temperature sensor to compensate for the transmitter, improve the measurement accuracy, reduce the temperature drift, with good long-term stability, high reliability and so on. The most humanized design of the external one-key zero function, to meet the safety requirements of hazardous occasions. Shortcut menu is convenient for operation, and can complete all the parameter settings, comprehensively improve the performance of the transmitter.
