Solutions for Loss of Process Visibility

SOLUTIONS for Loss of Process Visibility

All Jacoby-Tarbox sight flow indicators and sight windows with flat glass can be supplied with Dual Windows or with UniGlas windows.  If your specifications require an FM Approved assembly, then Dual Windows need to be specified.  UniGlas is a unique disc where glass and metal are fused into one single disc.  A ten to one safety factor is used in this design.  UniGlas is the ONLY disc available that may be re-used when an assembly is rebuilt.  UniGlas may be re-used because the stress introduced by the bolting is only applied to the metal and not the glass.

Concern: Chemically Aggressive Process Compromises Glass Application Issue Chemical attack compromises the integrity of the glass.  By the time the corrosion or erosion is visible to the operator, a dangerous change to the glass has taken place. Consequences:
  • Frequent maintenance required
  • Loss of Production
  • Replacement Parts
Best Solution: UniShield® Window Protection UniShield is your early warning device, showing changes in shield BEFORE glass integrity is compromised. Alternate Solutions: Independent Shield FEP, PCTFE (formerly KEL-F), or Mica shields can isolate the glass from the process in applications without vacuum.
Concern: "Dirty" Process Application Issue Process impedes view by sticking to window, leaving a film. Consequences:
  • Frequent maintenance required
  • Loss of Production
  • Replacement Parts
Best Solution (for Mechanical Cleaning): UniGlas® ONLY UniGlas may be removed, cleaned, and placed back in service.  All other "all-glass" discs, such as borosilicate and Quarts are "single use" and must be discarded upon disassembly. Best Solution (no disassembly): UniShield Window Protection with Phaeton® SL Light UniShield's "non-stick" properties, consistent with PFA, minimizes process adhesion.  Phaeton SL explosion proof and intrinsically safe lighting illuminates dark, dried on, and hard to see material build up. Alternate Solutions: UniShield or Phaeton SL alone
