Process Optical Dissolved Oxygen Sensor

Process Optical Dissolved Oxygen Sensor – Overview

This rugged, reliable sensor is designed to deliver accurate dissolved oxygen (DO) data across a wide measuring range. It features the latest optical technology for DO measurement and eliminates the replacement of membranes and reference solutions. The optical sensor cap is calibrated at the factory and requires no field calibration. The optical measurement technology resists abrasion and bleaching which allows for a long life in many harsh applications. It has built-in Modbus RS485 and 4 to 20 mA current loop outputs for ease of interface to existing control systems. The 3-2610-51 version includes the GF (S3L) digital interface for direct connection with the 9900 SmartPro® Transmitter and 9950 SmartPro® Dual Channel Transmitter. Additional features include a 10 m (32.8 ft) cable with stripped and tinned ends as well as a titanium temperature sensor for improved compatibility in saltwater applications.
