Macsensor IP66 High Precision Mems Air Wind Differential Pressure Sensor

Product DescriptionMacsensor DP825 micro differential pressure transmitter adopts silicon MEMS micro pressure chip. With temperature compensation,digital calibration, linear compensation, signal amplification, V/I conversion and other signal processing, temperature drift performanceand product stability has been improved. In addition, anti-surge, reverse polarity protection and other features improve product reliability.It is suitable for various dry non-corrosive gas pressure or differential pressure measurement, widely used in HVAC pipelines, pipeline flowrate tests, clean workshops, building automatic control and other fields.Product FeatureIndoor and outdoor differential pressure monitoringThrough the connection between the air pressure transmitter and the control instrument, when the indoor and outdoor differential pressure reaches the preset upper limit, the fan is started to decompress, and when the differential pressure reaches the preset lower limit, the fan is turned off. Anti-clogging filterThrough the connection of the air pressure transmitter and the control instrument, the differential pressure at the front and rear ends of the pipe filter is monitored in real time, and the upper limit of the differential pressure alarm is set to realize the early warning of filter blockage.Product Parameters ParameterDP825Pressure typeDifferential pressure, gauge pressureMeasuring range0Pa~±100Pa, 500Pa .. 1000Pa; 0kPa~2kPa, 10kPa .. 100kPaAccuracy±1.0%F.S; ±0.5%F.SElectrical wire2 wire3 wire4 wire4 wireSignal output4mA~20mA0.5V~4.5VdcI2CRS485Power supply12V~ 30Vdc5V~30Vdc3.3V~5Vdc5V~30VdcTotal current consumption23mA max
