美国walchem电镀药液自动分析添加系统

ANI化学镀镍自动添加控制系统 

ANI化学镀镍自动添加控制系统采用美国Walchem控制器。是应用光电原理在线分析电镀缸内镀镍溶液浓度的变化，能以克每升(g/L)或者盎司每加仑(oz/gal)来显示。使用此控制器在镀镍缸上能减少人工滴定检验的需要并增加生产能力，当到达***大“金属消耗”时更能自动地提示使用者从而减少资源浪费及增加电镀缸的寿命。只需设定好设定点就能得到准确的结果省去重复调校及校准的不便。 

ANI系列型号价格经济，内置微处理器以菜单形式控制，控制器可以有只测量镍或附带有PH控制功能从而省去另外添置PH控制器的需要。两个***泵输出用于镍及一个用于PH，每个都可统计泵的总运作时间，总添加量或“金属消耗”。用户可透过背光源LCD显示屏来查看镍浓度与设定点的差距。 

电镀缸外流通式感应器能节省宝贵电镀缸空间（不一定需要消泡程序）。光纤光电技术非常稳定及***的，不会受电镀缸***，颜色变化或沉淀物突增影响。ANI系列控制器用于自我检测，校准提示及4-20mA输出功能。 

◎浓度读数单位----以克每升(g/L)货盎司每加仑(oz/gal)，背光源LCD显示屏能以棒形图形式连续显示设定点与测量值的现状。 

◎选择性PH控制继电器及输出端可用以添加控制或稳定容易，每个输出端能统计以流量或时间为单位的总补充量。 

◎不一定需要消泡程序----类比讯号调节剂专利的软件计算法省去传统的消泡程序原件。 

◎测量规格 

         浓度      酸硷度     温度 

范围    0.1-10g/L   0-14pH    0-80℃   

分辩率  0.01g/L    .001pH     .05℃ 

准确度  0.1g/L     &plu***n;.01pH     &plu***n;.1℃  

◎参数调整----用户可调整浓度设定点，警报设定点（高位及低位），盲点设定及开泵时限，连锁功能透过外接原件（例如流量阀）来释放输出端继电器的开或关。

◎程控密码锁----保护设定参数，以4位数字为密码锁。

◎自我诊断----软件，控制器电子部分及感应器不间断地实时监察而不会令控制器处于离线，所有需要的操作动作都会以讯息显示出来。

◎安全标准----WNI系列控制器完全遵守UL，CSA及CE安全规格执行

Walchem’s WCU410 Copper Controller and WNI Nickel Controller are optoelectronic on-line analyzers that measure the actual concentration of copper or nickel in solution. They are used in a variety of applicati*** including electroless plating baths and microeth baths (including oxide-replacement types).

The WCU410 may be switched from electroless copper to microetch via the menu, eliminating the need for a second controller. It reduces the need for manual titration, improves yield, and in microetch applicati*** improves productivity by reducing the frequency of bath change-outs.

The WNI410 is ***ailable as nickel-only, or with a pH control option which may be added in the field. Two separate pump outputs for nickel and reducer and another for pH are used, each of which is capable of totalizing either pump on-time, volume pumped, or metal turnovers.

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 copper or nickel measurements, and relay status. Download logs from the USB stick to a PC at your convenience. It couldn’t be easier!

SUMMARY OF KEY BENEFITS

Concentration Read in Units
Selectable between grams per liter (g/L) or ounces per gallon (oz/gal). Backlit digital display also acts as a bar graph for a continuous “visual summary” of measurement versus set point.

Operator Adjustable
Concentration set point, alarm set points (high and low), dead band and pump on time are all easily adjustable. An interlock feature allows external devices (such as a flow switch ) to interlock control relays.

Simple, Integrated Data Collection
Download stored data from the controller to a USB stick. Use the data to simply and easily validate system performance. The data and event logs show copper or nickel values, as well as accumulated chemical feed and relay activation times.

Four Separate Control Relays & Outputs (WCU)
May be used to add copper, caustic, formaldehyde or chelator/stabilizer chemistries. Each output has a replenishment totalizer which may be set in units of time or volume.

Optional pH Input Board (WNI)
May be used to add pH adjustment chemistry. Output has a replenishment totalizer which may be set in units of time or volume.
