AV720 Monocrystalline Silicon Differential Pressure Transmitter uses high stability differential pressure chip.The monocrystalline silicon design achieves internationally leading high-precision, ultra-high overload performance and superior stability. The embedded signal processing module achieves a perfect combination of static pressure and temperature compensation, achieving high accuracy and long-term stability over a wide range of static pressure and temperature changes.

The AV720 Monocrystalline Silicon Differential Pressure Transmitter uses voltage power supply, and convert the measured differential pressure value into 0.5-4.5V Ratiometric, 0-5VDC, 4~20mA or 4~20mA+RS485-MODBUS protocol current signal.
