In-plant detectors are similar in design to the portable detectors. The key difference being, the inspection surface moves past the stationary detectors.
For thicker coatings it has fully adjustable output voltage from 5 kilovolt to 25 kilovolts. For very demanding conditions, a sensitivity switch offers additional control.
Wet Sponge Holiday Detector for Plant or Stationary Operations is highly sensitive and accurate. A uniform coating of only one mil of paint or other non-conductive material over a metal surface is sufficient to repel a small current flow. If a pin-hole holiday is encountered, moisture from the sponge will seep into the hole and create a free path for electrical flow, activating the signal horn.
Continuously monitors the coating line process as reinforcing bar runs through the RBRS dual-roller wet sponge electrodes unit. When a holiday is discovered, a red light flashes at the appropriate station on the detector unit for a visual indication, and the unit sends an eletrical output to a plug on the back of the unit. The MSRB signal output plugs drive any 120 Volt AC customer furnished horn, bell, recorder or computer.
