Process Optical Dissolved Oxygen Sensor with Modbus output MBRTU-PODO Version 2

Introduction

MBRTU-PODO is Process Optical Dissolved Oxygen Electrode with optic technology is based on the proven method whereas oxygen concentration is determined by the luminescent quenching of a dye embedded on the sensor surface. Unlike polarographic or galvanic sensors, this optical sensor does not require filling solutions nor a “warm-up” time. The electrode comes with 1/2” NPT threads, a durable stainless steel body and is submersible. Output is Modbus RTU for easily integrating with any PLC, controller, SCADA, BMS or IoT gateway.

• Affordable, complete electrode system

• Fully documented RS485 output for existing PLC/controllers/monitors

• No electrolyte solution to replenish

  Replaceable sensor cap with >2 year life expectancy

• No calibration or replacement sensor cap for at least 1 year in most applications

• Saltwater compensation

• On-probe pressure sensor for compensation

• Sample flow not necessary for measurement accuracy

• Standard ModbusRTU output;

Typical Applications

MBRTU-PODO is used in monitoring of Dissolved oxygen in:

Waste water;
