For safety-related parts of a control system Functional Safety Guidelines state the need for redundancy and diagnostics in the structure. In some cases a fully redundant monitor with two fully separated parallel measuring channels with separate vibration sensors are needed
The fully Redundant SIL 2 / PL-d Cat 3 Vibration Monitors from PCH Engineering are suitable for enhanced protection according to EN 13849 and permanently monitors critical and dangerous machinery. The build-in 1002 D architecture will leave the alarm function fully operational although one of the two parallel measuring channels is at fault.
Price attractive alternative
Instead of placing two individual vibration monitors next to each other the PCH solution is an integrated solution with two individual vibration monitors in one housing. This offers a price attractive alternative to traditional solutions.
Redundant vibration monitors from PCH offer the same easy way of installation as PCHcompact Range: Only a M12 mounting stud is needed.
