HD3051 Monocrystalline Silicon IntelligentDifferential pressure transmitterThe components are made of monocrystalline silicon using advanced MEMS technology from Germanysensor chipThe globally unique single crystal silicon double beam suspension design achieves internationally leading high accuracy and excellent stability with ultra-high overvoltage performance. Embedded intelligent signal processing module, achieving a perfect combination of static pressure and temperature compensation, can provide extremely high measurement accuracy and long-term stability under large range of static pressure and temperature changes.

HD3051 can accurately measure differential pressure and convert it into an output signal of 4-20mADC. This sensor can be operated locally through three buttons, or remotely through a universal handheld device, configuration software, and mobile app. It can display and configure without affecting the output signal of 4-20mADC.
