New Design Single Crystal Silicon Micro Differential Pressure Transmitter Detail Introduction :
Application:
Oil, chemical, mechanical equipment, electric power, papermaking, steel, cement and other occasions for accurate pressure and differential pressure measurement, It is a high-quality Pressure Transmitters & Sensors.
Description:
Hanyi monocrystalline silicon micro-differential pressure transmitter adopts the monocrystalline silicon sensor chip made of German advanced MEMS technology, and the world's original monocrystalline silicon double beam suspension design, which achieves the world's leading high accuracy and ultra-high overpressure performance Excellent stability. The embedded professional signal processing module realizes the perfect combination of static pressure and temperature compensation, which can provide extremely high measurement accuracy and long-term stability under a wide range of static pressure and temperature changes.
HPM81-DR single crystal silicon micro differential pressure transmitter can accurately measure micro differential pressure and convert it into (4-20) mA DC output signal. The transmitter can be operated locally through three buttons, or remotely operated by a universal handheld operator, configuration software, and mobile phone APP. It can display and configure operations without affecting the output signal.
Features:
◆ High accuracy and high stability In the measuring range of -1～1kPa, high accuracy measurement can be carried out, and the highest can be compressed to -50～50Pa for stable use
◆ Excellent environmental adaptability Intelligent static pressure compensation and temperature compensation, protect the transmitter from the influence of temperature, static pressure and overpressure, and control the comprehensive measurement error to a minimum
◆ Flexible range compression
