QM42 Differential Pressure Sensor

The QM42 Differential Pressure Sensor offers accurate low-differential pressure measurement of air and non-condensing, non-corrosive gases in applications such as air filter monitoring, isolation and clean rooms, building pressurization and dust collectors.

• The differential pressure sensor is used to measure the difference in airflow between intake and exit – such as airflow through a filter – to make decisions on preventive maintenance or to maximize efficiency of industrial equipment.
• The QM42-DPS1-2Q model senses up to +/- 1 in WC, using RS-485 Modbus serial communication
• The QM42-DPS20-2Q model senses up to +/- 20 in WC, using RS-485 Modbus serial communication
• The QM42-DPS1-1Q model senses up to +/- 1 in WC, using 1-wire serial communication with Q45DPSD transmitter node
• The QM42-DPS20-1Q model senses up to 20 +/- 20 in WC, using 1-wire serial communication with Q45DPSD transmitter node
