Get the galvanizing industry's most precise and accurate bath level
Since safety standards require the Galvalibs 2.0 to constantly and accurately monitor the analyzer’s insertion depth, this security feature also reveals the exact location of the bath surface. That’s yet another reason you can count on the Galvalibs 2.0 to precisely and constantly provide the bath level.
Talk to an expertMost accurate bath level in the industry
Bath-level monitoring is key to ensuring high-quality galvanized products. Most analyzers are based on surface tracking from the outside, so they are strongly affected by surface actions, such as drossing activities or surface contamination, such as top dross. Since the information gathered by the Galvalibs 2.0 originates from the depth of the bath, bath-level measurement is extremely accurate. With a demonstrated accuracy of 0.4 mm, it’s the most accurate bath-level measurement in the industry.
Surface dross insensitive
Since the Galvalibs 2.0 measures the bath level from the bottom up, surface conditions are irrelevant to the measurement. Unlike surface tracking technologies, surface dross has no impact on the bath-level value of the Galvalibs 2.0
Not affected by waves
The measurement is directly related to the mass of liquid zinc above the insertion point. As a result, the analyzer is oblivious to waves on the surface due to bath dynamics.
No effect from drossing
With its bottom-up measurement method, surface activities such as drossing, do not affect the accuracy of the bath level measured.
Continuous monitoring via level 1 and level 2
Bath-level data is provided to the network in real time via analog signal output or Ethernet/PLC outputs, facilitating real-time feedback control.
Fail-safe measurement
The combination of a “no-false-positive” pressure sensor with interlock mechanical positioning switches provides a fail-safe recording of the bath level, increasing confidence for using the data in automated feedback control of ingot insertion.
Built-in: No additional hardware needed
Bath-level data is obtained from a safety device that confirms the insertion depth of the probe lance in the bath prior to firing the Galvalibs 2.0.
Key advantage of bath-level measurements
Real-time viewing of ingot feed
By simultaneously displaying the bath level and bath chemistry, operators get a real-time display of ingot feed impact. This gives operators the advantage of immediately acting on unforeseen effects.
Easy bath-level control
Galvalibs 2.0 data output is available via Analog, PLC or Ethernet connections. Bath-level information can then be used to easily set up automated ingot feed control. With the feedback, a stable bath level is easily achieved, as seen in the figure, avoiding contamination of the bath from surface residue collected on the snout and side walls.
