The Oxymac, Elecdit, and DE800 sensor interface boards are control and measurement devices 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 DE800 interface also includes the heater supply, Oxymac50 and Elecdit require an external heater power supply.
