WDEC410 U voltage output sensor 1 sensor 2 USB Voltage 1 = 120 VAC, prewired 5 = Hardwired, cable glands Metering Pumps The E-Class is the most innovative and comprehensive metering pump product line in the world. Over 50 years of pump experience and a commitment to superior mechanical design has led to development of many industry firsts, including 360 stroke-per-minute technology, IP67 waterproof construction, and the world’s highest capacity solenoid metering pumps. Sensors (Select 2 in alphabetical order for WDEC) N = No sensor Four conductivity 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. WIND WebMaster® Industrial Water Controllers Output N = No 4-20 mA data output 4 = One (1) Isolated 4-20 mA output 2 = Two (2) Isolated 4-20 mA outputs 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! Walchem’s WebMaster Industrial (WIND) Controller sets a new standard for Industrial Water Treatment Controllers. WIND has a flexible multi-I/O platform, a wide range of analytical sensor measurement capabilities, and an extensive assortment of integrated communications and data handling features. 0.1 to 1.0 mS/cm A = Submersion PEEK sensor B = In-line PEEK sensor w/SS adapter C = Submersion CPVC sensor D = In-line CPVC sensor w/CPVC adapter WebAlert® Remote Monitor Walchem’s WebAlert is the first stand alone remote monitoring device that can web enable your installed equipment without having to replace or upgrade it. 1.0 to 10.0 mS/cm E = Submersion PEEK sensor F = In-line PEEK sensor w/SS adapter G = Submersion CPVC sensor H = In-line CPVC sensor w/CPVC adapter USB FEATURES U = Integrated datalogging, event/reset logging, and configuration file import/export 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. 10.0 to 100 mS/cm I = Submersion PEEK sensor J = In-line PEEK sensor w/SS adapter K = Submersion CPVC sensor L = In-line CPVC sensor w/CPVC adapter 100 to 1000 mS/cm M = Submersion PEEK sensor O = In-line PEEK sensor w/SS adapter P = Submersion CPVC sensor Q = In-line CPVC sensor w/CPVC adapter The WEC/WDEC410 Series Single and Dual Input Electrodeless Conductivity Controllers measure conductivity of a solution via an encapsulated, noncontacting 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.

Five Boynton Road Hopping Brook Park Holliston, MA 01746 USA Phone: 508-429-1110 www.walchem.com 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.
