For critical applications, Kalenborn markets systems that indicate the possible wear of protective linings, thereby informing the operator in time to take necessary action. Indicator stones are integrated at different heights in a ceramic wear protection lining. Increasing wear reveals the color of the stones, thereby indicating the condition of the protective lining and how much material has worn away. Visual wear detection is suitable for individual parts or complete plants.
Wear protection monitoring is used for pneumatic conveying lines when it is necessary to reliably prevent toxic or environmentally harmful substances from escaping.
The exterior of the wear protection lining is equipped with a low voltage measuring conductor. If the wear protection layer inside the piping wears through due to abrasion at any point, the conductor will be interrupted there.
This triggers an alarm and – in combination with suitable evaluation logic – indicates the affected section of piping or automatically shuts the plant down.
Wear protection monitoring is available for all materials and even for combined linings.
Support structure and wear protection lining are fitted with a removable pin installed in a threaded hole. Upon removal, the length of the pin indicates the thickness and condition of the protective lining.
