Monitoring manways
Requirement
A typical application in the food industry is the reliable monitoring of manways. The purpose is to protect the maintenance staff against injuries caused by moving machine and plant parts.
Implementation
Fail-safe inductive sensors of category 4 and SIL3 directly detect the stainless steel cover (manway) without contact. A special counterpart is not necessary.
Customer benefits
A special counterpart such as a magnet or coded target is no longer necessary for the function of the fail-safe sensor. The fail-safe inductive sensor directly detects metals such as high-grade stainless steel or mild steel, i.e. materials that are used on the machine anyway.
