Product Description

HPM81 single crystal silicon differential pressure transmitter adopts single crystal silicon sensor chip made by advanced German MEMS technology and the world's original single crystal silicon double beam suspension design, achieving internationally leading high accuracy, ultra-high overpressure performance and excellent stability. The built-in professional signal processing module realizes the perfect combination of static pressure and temperature compensation, and can provide extremely high measurement accuracy and long-term stability under a wide range of static pressure and temperature changes.


Features:

• High accuracy & stability, environment suitability
• Intelligent static pressure compensation and temperature compensation
• Flexible range of compression
• Easy to operate,built-in three-button with quick operation and field adjustment functions
• With 5 bit LCD digital display with backlight
• Multiple display functions(mA,Pa,kPa, MPa,bar,mbar,%,psi,mmH2O)
