Description :

The Oxymac, sensor interface board is a control and measurement device for Honeywell's range of dynamic, highly accurate oxygen sensors. The ability of these sensors to operate without any reference gas makes them often ideal for many applications, including combustion and environmental control.

Honeywell oxygen sensors using zirconia-based sensing elements require external connection to an electronic measuring circuit to control sensor operation and signal processing. A heating element on the sensor produces the 700 °C required for the ZrO₂ to achieve its operational temperature. These interface boards supply the sensor with the necessary circuits to provide this control and processing, while also providing sensor calibration. The Oxymac50 requires an external heater power supply. For applications where an external heater supply is not feasible, then Honeywell's DE800 interface should be considered.
