Walchem’s Copper and Nickel Sensors are optoelectronic devices that are used in conjunction with Walchem’s on-line analyzers in a variety of applications including electroless copper or nickel baths, microetch baths and a number of other chemistries that contain more than 0.10 grams/liter (g/L) of copper or nickel ions. Flow-through sensors are available for out-of-tank monitoring of solutions, and immersible sensors (copper only) are available for direct in-tank monitoring.
Benefícios:
- 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.
