Precise measurement of oxygen concentration in gas mixtures

Mar 14 2023

LogiDataTech‘s MF420-O-Zr oxygen sensor is a cutting-edge solution for measuring oxygen concentration in gas mixtures. The sensor is based on a dynamic process in two zirconium dioxide slices that form a sealed chamber, offering linear measurement over the entire range.

This oxygen sensor has a built-in diagnostic function that monitors its performance during operation and indicates any hardware or sensor element malfunctions. It eliminates the need for a second oxygen sensor.

The MF420-O-Zr can be calibrated without reference gas in atmospheric air, and outputs measurement values through both an analogue channel (4 - 20 mA or 0 - 10 V) and a digital channel, which also transmits error messages.

The MF420-O-Zr is available for a measuring range of 0.1 to 25 Vol.-% oxygen, with an analogue interface of 4-20 mA or 0-10 V and an independent digital output. Its diagnostic function ensures a fail-safe operation.

The MF420-O-Zr oxygen sensor has been certified to comply with DIN EN 50270:2015 type1 and type2 and the EMC-directives 2014/30/EU. The device is delivered pre-calibrated, with maintenance intervals meeting safety requirements, but with a recommended six-month monitoring and five-year replacement cycle. The device supports both electrical and manual calibration.
