内置微处理器，WDP系列控制器非常容易地安装、编程及操作。美国或欧洲标准的标准液自动辨认使电极校准简单又方便。控制器由用户定义校准周期后能准时地提示用户重做校准。
WDP系列控制器能适合我们的WEL系列pH/ORP电极使用，其提供与众不同的可靠测量技术不会有接地回路的问题。同时也提供NEMA 4X系统，不会像BNC插头无遮蔽的有容易弄湿或腐蚀情况出现；安全又可靠的方法。透过自我诊断能简单地排解电极的故障疑难。
留心观察W300系列控制器的工程设计会发现是易用、一体化、耐用的产品。
The WPH410/420 and WDP410/420/440 Series pH/ORP on-line process controllers are designed for a broad range of industrial, commercial, and municipal water treatment applicati***. WPH controllers are easily configured to accurately measure pH or mV (ORP) values from Walchem’s WEL and WDS differential combination electrodes, or any conventional combination electrode.
A versatile output configuration allows you to program up to four outputs in a variety of control modes. Select from on/off mechanical relays or pulse proportional control for direct connection to metering pumps. The easy-to-use menu format and pre-wired, pre-mounted panel system opti*** make set-up and installation quick and simple.
Integrated datalogging is ***ailable to validate system performance. A USB memory stick is all that’s needed to extract data and event logs that include electrode 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
Versatility for a Broad Range of Applicati***
Select from pH or ORP measurements and from five output opti***. Use In-Range to control a solenoid valve to dump a batch treatment tank when measurement value is within limits, or program for Out-of-Range Alarm in waste treatment applicati*** when the measurement value is too high or low.
Ideal for Harsh Environments
The NEMA 4X enclosure, combined with Walchem’s WEL and WDS electrodes, provides a waterproof system with no BNC connectors 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 batch tank.
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 pH/ORP and temperature values, as well as accumulated chemical feed and relay activation times
Dual Input Reduces Cost
Dual pH or ORP electrode inputs allow one controller to take the place of two, reducing cost and space requirements, and simplifying installation.
Walchem’s WEL Series electrodes are cost-effective differential pH and ORP electrodes for industrial applicati***. They are modular in design with a rugged CPVC housing which contains the electronics; pH and ORP cartridges can easily be connected or replaced in minutes without tools. The cartridges feature a unique threaded interlock connection and a double o-ring seal, ensuring a watertight fit and secure seating at all times.
