OXY-LC-485 Zirconia oxygen sensor RS485 output oxygen transmitter board
Product Features:
- The circuit can supply power to and control SST series dynamic oxygen sensors.
- Adopts RS485 Modbus RTU communication protocol, enabling full control of the sensor operation and acquisition of sensor diagnostic information.
- With appropriate software filtering settings, it achieves fast response and stable oxygen concentration output values.
- Can be calibrated in air (20.7% oxygen) or other environments with known oxygen concentration. The software delays 5 minutes after starting the heating rod to prevent calibration before the sensor reaches stable operating temperature.
- Adjustable communication settings allow changing the slave address of the interface, supporting up to 32 interfaces on the same bus, suitable for fields requiring multi-oxygen reading.
- Reverse voltage and transient overvoltage protection on the power supply connection.
- PCB is equipped with screw terminal blocks for wiring.
Application Fields:
- Combustion control: Oil, gas, and biomass boilers.
- Composting.
- Laboratory and building air quality monitoring, as well as personal safety monitoring in enclosed spaces.
- Industrial process control: Gas mixing processes for welding and steelmaking.
- Oxygen generator systems.
- Medical fields.
- Scientific experiments: Respiratory research on communities, microorganisms, plants, and animals.
- Food and beverage packaging, and occasions requiring low oxygen concentration such as fermentation, rust prevention, corrosion protection, fire prevention, inerting, and purification.
