Product Specification

Oxygen Sensor Interface Boards Description
The Oxymac50, 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 ideal for potential applications such as 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 [1292 °F] 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, while the Oxymac50 and Elecdit require an external heater power supply.

Oxymac50 is a recently upgraded interface that offers similar performance to the Elecdit board but operates from a 24 Vdc power supply.

The DE800 interface offers the features of the Oxymac50 but also contains the heating element power source.

The Elecdit interface was developed for Industrial applications and offers a level of noise protection. It operates from a ±15 V supply.

Oxymac50 and DE800 are the recommended interfaces for new applications.

The interfaces are supplied ready for mounting into customers' enclosures. Oxymac50 a 15-pin D type connector, DE800 has screw connector block and Elecdit has 2,5 mm x 2,5 mm [0.1 in x 0.1 in] pin connector.

Oxygen Sensor Interface Boards Features and Benefits
• Provides the necessary circuits to control Honeywell oxygen sensors which removes the need to implement sensor control circuits within the customers' equipment
• Functional testing and calibration in ambient air removes effects of barometric or application pressure
• PCB board format provides ease of mounting and calibration access
• Linear output of measured oxygen content in voltage or current format for a flexible interconnection
• Low power consumption for lower running costs

Oxygen Sensor Interface Boards Potential Applications
• Boiler combustion controls
• Aircraft oxygen generation systems
