[Product Overview]

HD3351 Monocrystalline Silicon IntelligentPressure transmitterThe monocrystalline silicon pressure sensing chip made with advanced MEMS technology from Germany and the globally unique monocrystalline silicon double beam suspension design have achieved 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.

Single crystal silicon pressure transmitter can accurately measure 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.

【 Application Fields 】

Electricity/City Gas/Other Corporate Businesses
