MSR Germany Toxic gases and oxygen with analog outputBy ALVI
Exchangeable sensor unit including digital value processing, temperature compensation and self control for the continuous monitoring of the ambient air.
The sensor unit MC2 houses a module with μController, analog output and power supply in addition to the electrochemical sensor element including amplifier. The μController calculates a linear 4 – 20 mA (or 2 – 10 V) signal out of the measurement signal and also stores all relevant measured values and data of the sensor element.
Calibration is done either by simply replacing the sensor unit or by using the comfortable, integrated calibration routine directly at the system.
The μGard®2 Sensor MC2 is used for the detection of toxic gases or for oxygen monitoring wherever a typical 4 – 20 mA (or 2 – 10 V) signal is required.
Digital measurement value processing incl. temperature compensation
Internal function control with integrated hardware watchdog
Data / measured values in μC of the sensor unit, therefore simple exchange uncalibrated <> calibrated
High accuracy, selectivity and reliability
Low zero point drift
Long sensor life time
Hardware & software according to SIL2 compliant development process
Easy maintenance and calibration by exchange of the sensor unit or by comfortable on-site calibration
4 – 20 mA (or 2 – 10 V) analog output with selectable signal output for special mode, fault etc.
Reverse polarity protected, overload and short-circuit proof
Housing for integration of the sensor unit
