The HPM81 Monocrystalline Silicon Differential Pressure Transmitter, utilizing advanced MEMS technology from Germany, achieves high accuracy, super high overvoltage, and stability. Its monocrystalline silicon core and monocrystalline twin beams suspension design are globally original. With a built-in professional signal processing module, it combines static pressure compensation and temperature compensation, ensuring high measuring accuracy and long-term stability even under varying static pressure and temperature. The HPM81 accurately measures differential pressure and outputs a 4-20mADC +Hart protocol.
