The WEC/WDEC410 Series Single and Dual Input Electrodeless Conductivity Controllers measure conductivity of a solution via an encapsulated, non-contacting sensor to control replenishment pumps and alarms. They may be installed in a variety of very harsh chemical control applications, including oily cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated chemicals up to a conductivity of 1000 mS/cm.
Four conducivity ranges may be selected to configure the controller over a wide range of applications. Choice of measurement units is μS/cm, mS/cm, ppm and % concentration.? The non-contacting, toroidal sensor technology is immune to thin coatings and the contamination and calibration problems that direct contacting sensors are prone to.
Integrated datalogging is available to validate performance. A USB memory stick is all that’s needed to extract data and event logs that include conductivity measurements, temperature and relay status.? Download log files from the USB stick to a PC at your convenience.? It couldn’t be easier!
SUMMARY OF KEY BENEFITS
Dual Input Reduces Cost
WDEC can accept two electrodeless conductivity sensor inputs, allowing one controller to take the place of two, reducing cost and space requirements, and simplifying installation.
Versatility for a Broad Range of Applications
Choose PEEK sensors for higher temperature, more aggressive chemical applications, or CPVC sensors for lower temperature, less aggressive chemical applications.? Both are available for in-line or submersible applications.? On/Off and Time Proportional control modes are menu selectable.
Ideal for Harsh Environments
The rugged, NEMA 4X enclosure, combined with Walchem’s electrodeless conductivity sensors, provides a waterproof system with no metallic parts exposed to wet or corrosive environments.
Built-in Safety Features
Programmable output limit timers prevent run-away chemical addition. Digital Interlock Input may be used from a flow switch or level input to prevent chemical addition based on a stagnant sample, or control of an empty tank. The alarm relay notifies plant personnel of alarm conditions as soon as they occur.
Simple, Integrated Data Collection
Download stored data from the controller to a USB stick with the press of a button. Use the data to simply and easily validate system performance, document compliance, and reduce liability. The data and event logs show conductivity and temperature values, as well as accumulated chemical feed and alarm relay activation times.
