Process Optical Dissolved Oxygen Sensor with Modbus output MBRTU-PODO

SKU: MBRTU-PODO

Doc No: MBRTU-PODO-DS-EN-10

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 dual ¾” NPT threads, a durable Ryton 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;

Aquaculture;

...
