OXY-LC-A25-455
Overview
The OXY-LC-A25-455 is a high-performance oxygen sensor control board designed to interface with SST Sensing's zirconium dioxide O2 sensors. It provides a linear 4-20mA output representing 0.1-25% oxygen concentration and features an integrated pressure sensor for automatic barometric compensation. This board operates on a wide 8V to 28V DC supply and includes RS485 and PWM interfaces for flexible system integration.
Why Choose This Part
The built-in barometric pressure sensor ensures measurement accuracy despite atmospheric fluctuations, while the zirconium dioxide technology offers high stability and a long operational lifespan. Its dual communication capability (analog 4-20mA and digital RS485) allows it to be used with both legacy PLCs and modern networked control systems.
Applications
Getting Started
Connect the zirconium dioxide sensor via the long-cable interface and provide a 24VDC power supply capable of 600mA to support the sensor heater. Use the RS485 interface for digital configuration and calibration, or monitor the 4-20mA loop for direct integration into industrial control loops. Ensure the board is mounted in a well-ventilated enclosure as the sensor heater generates significant thermal energy during operation.
