The CM-420 Combustion Monitor provides a 7” touchscreen interface to monitor the oxygen percentage in a stack. A 4-20mA output, Modbus TCP or Modbus RTU connection allows this measurement to be shared with a PLC, SCADA or building management system.
The CM-420 Combustion Monitor can be used whenever an onboard means of oxygen monitoring is required. The CM-420 Combustion Monitor is also perfect for fully metered oxygen trim applications when the 4-20mA output is connected to a PLC.
The NXCESO2 sensor used is a wide-band lambda sensor with a zirconium dioxide dual cell, with integrated heater and pump control. Probes are available in 216mm (8.5”) or 407mm (16”) insertion depths. Stack temperature is also provided by the integrated type-K thermocouple, allowing measurement up to 426°C (800°F). The sensor is self-calibrating and is designed to be maintained without having to be removed from the stack.
