RS485 Differential Pressure Transmitter Sesnor Air Negative Duct

Negative Duct Air Rs485 Differential Pressure Sesnor Transmitter

Features Negative Duct Air Rs485 Differential Pressure Sesnor Transmitter

Fully intelligent circuit board, automatic compensation and linear calibration, strong isolation of interference, to ensure signal stability
It has reverse protection and current-limiting protection circuit. When the positive and negative poles are reversed during installation, the transmitter will not be damaged. When abnormal, the transmitter will automatically limit the current within 35MA.
Soft wire, polyurethane wire, anti-corrosion, high and low temperature resistance. The tail of the wire is sealed with a polymer sieve, which can ensure the air permeability of the wire and prevent water molecules from entering
The default is stable 0.25% accuracy, can be customized 0.1% accuracy and higher
