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
DescriptionNegative Duct Air Rs485 Differential Pressure Sesnor Transmitter
FM113 Micro-differential transmitters are consist of both isolation membrane
differential pressure sensor and integrated
circuit, Has characteristics of high precision, good stability, high reliability and
good sensibility. Also can build high-performance
microprocessor(MCU)which can correct nonlinearity and compensate
temperature drift. Achieve accurate data transfer, local
equipment diagnoses and long-distance bidirectional communication.
