O2 Sensor

02 sensors from Senmatic measure O2 in gaseous media within a concentration range from 0.10% - 25.0% O2. This sensor uses a zirconia electrolyte cell in a amperometric design, this offers repeatability, long-term stability and high accuracy for the sensor. The sensor features a Modbus communication protocol, which makes it easy to connect directly to a controller.

  • Plug and play solution
  • High accuracy
  • Small temperature dependence of sensor signal
  • Low interference with other gases
  • Long service life
