Differential pressure sensor QM42

RS-485Modbusfor air

QM42 differential pressure sensors offer accurate low-differential pressure measurement of air and non-condensing, non-corrosive gases. This measurement is critical for air-filter monitoring, isolation and cleanroom applications, building pressurization, and dust-collection systems. The sensor conveniently connects to standard wiring systems using either serial or Modbus communication. Pressure measurement scaled in inches of water, PSI, and Pascal Versions with 1-wire serial as well as RS485 Modbus communication Hose barb process connection
