M2000 Dual Sensor ODO and TSS

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The InsiteIG Model 2000 dual channel analyser is a unique system that combines advanced electronics with solid-state optical sensors. The analyser will accept any combination of two sensors, (DO or SS) and automatically configure for the correct operation. The system allows for flexible and economical mixed liquor monitoring and control. The DO sensor does not need membranes, fill solutions, nor routine calibrations and maintenance. The SS sensor is based on near infra-red technology, which eliminates inaccuracies caused by changes in the process colour or changes in particle size.

LEGACY MODEL- New model available DCA 

The Model 2000 Mixed Liquor Analyser is a two channel analyser designed for the continuous measurement of dissolved oxygen and/or suspended solids in mixed liquor aeration basin. The microprocessor-based electronics of the Model 2000 analyser provide a high degree of flexibility and ease of use. The instrument is designed to operate with any combination of InsiteIG sensors in a variety of applications.

The DO sensor to be used with this analyser is an optical type sensor that measures the fluorescence and quenching reactions of a ruthenium complex that is immobilised in a sol-gel matrix. The SS sensor operates on the principle of single gap infra-red light absorption as a means of detecting the presence of suspended solids.

Analyser/Transmitter Outputs
Analogue
0 to 20 or 4 to 20 milliamp (user selectable) for DO
0 to 20 or 4 to 20 milliamp (user selectable) for SS
Digital communication Modbus RTU RS-232
Relay There is one independent programmable set point control relay for each channel. These relays are Form-C with contacts rated 10/6 amps resistive load at 125/250 VAC. Two Form-A relays with contacts rated 10/6 amps resistive load at 125/250 VAC are used for the jet clean function. The connections for the relay outputs are available from TB6.
