Product Description

Siemens QSA2700 Dust Particle Monitor, a fine dust particle sensor is designed to measure and relay PM2.5 and PM10 indoor concentrations. It has a built-in proximity sensor and enters energy-efficient mode if no interference has been observed (around 1 m) in the last few minutes in front of the sensor. In energy-efficient mode, the display is off and the sensor operates and constantly transmits signals. This 3-family QSA set of QSA2700 is display-free, and QSA2700D has an LCD panel, AQS2700 serves as the replacement sensor module, MODBUS Communication Selection, too.

Features of  Siemens QSA2700 Dust Particle Monitor:

  • The fine dust room sensor is designed to measure and transmit indoor concentrations of PM2.5 and PM10.
  •  0…10 V and Modbus output
  • Configurable Modbus parameters
  • Plug&play configuration for Siemens ClimatixTM controller
  • For QSA2700, 3-color LED service indication
