Introduction

Continuous online monitoring and control for any aqueous solution to accommodate a range of sensors

Description
The SS (Suspended Solids) controller (DWA-2000A-SS) Panel mount microprocessor has been built
and designed to provide years of trouble free operation.

It is designed to be only mounted in a panel.

This SS controller features accuracy to within 3% of full scale.

Control
When control of SS is required, this controller features a high and low relay output contact, or 4-20mA output which can be utilised to control sludge valves, WAS or RAS pumps based on plant operation design parameters.

Probe Cleaning Output
The added feature that this controller has, compared to others in the market is a sensor clean relay output,
which can be utilised to control a solenoid for air or water jet cleaning, or a wiper cleasning of the sensor surface.
(Especially useful in waste / industrial water plants)

Features
*Microprocessor based Digital Program Controller
*Isolated DC (4-20/0-20/0-24 mA) Output Transmission
*Automatic Cleaning Control Function
*Low-cost For User Satisfaction
*CE Mark Accredited
