O2 interface Board Only

SST zirconia sensor interface boards remove the need for customers to implement their own control electronics within the application. These boards provide a high accuracy and linear output over a variety of output communication options. Both board types can allow for the capability of manual or automatic calibration.

The O2I-Flex is a flexible, all-in-one solution, necessary to power and control SST’s range of dynamic zirconia oxygen sensors. It provides a selectable Oxygen measuring range and can provide simultaneous analogue and RS232 output signals. The O2I-Flex is a good starting point for an initial test setup. After testing, most setups can translate into a fixed OXY-LC sensor and board combination. Allowing the user to take advantage of the advanced operation settings (sensor diagnostics, standby mode and built in barometric pressure compensation).

The OXY-LC Interface boards are a family of boards with fixed settings and advanced operational features. Allowing a simple plug and play approach for customers who know exactly what they need.
