Electrochemical sensor including digital value processing and integrated self-diagnosis, for the continuous monitoring of the ambient air to detect toxic gases or oxygen.
The intelligent MC2 Sensor for detection of toxic gases or oxygen monitoring includes an electrochemical cell and electronics with a measuring amplifier and a μController as well as a module with a terminal for the analog output and the external power supply. The μProcessor converts the sensor’s measuring signal into a linear 4–20 mA signal (or 2–10 V). All relevant data and measured values of the sensor are stored fail-safe in the internal memory of the μProcessor.
The maintenance of the device can be done either by simply exchanging the sensor or by using the integrated, comfortable calibration routine directly at the system.
The PolyGard®2 MC2 Sensor used to detect toxic gases or to monitor the oxygen content in the ambient air when an analog 4–20 mA (or 2–10 V) signal is required.
