Differential Pressure Transmitter

ADP

ADP series differential pressure transmitter utilizes the temperature compensated CMOSense sensing element to ensure its stability as well as excellent reproducibility of the pressure of air and non-aggressive gases (N2 or O2) with superb accuracy and no offset drift. Three pressure measurement ranges -25 to 25 Pa, -125 to 125 Pa and -500 to 500 Pa are optional to the users. Users can easily select the three points operating pressure ranges from negative to zero to positive pressure by jumper in the PCB. The ADP series transmitter equipped with optional analog outputs 0 to 10 VDC and 0 to 20 mA as well as digital RS485 interface with industrial standard Modbus RTU protocol which could be interfaced with chart recorders, data loggers, PLC, computerized monitoring and control systems. The wall mount enclosure is fully encapsulated with rated IP54 to provide a great protection and make it suitable for harsh environment. Meanwhile, the package includes remote plastic connecting tubes to acquire the air pressures from two places. The differential pressure transmitter is perfectly designed for negative differential pressure isolation room, mechanical system engineering, environmental engineering, heat exchanger and used with Pitot tube for wind speed measurement and etc.
