Detecting leaks in chemical containers

The chemicals used in wet processes collect in process tanks on the machines and can be very dangerous. To protect persons and processes, leaks must be reliably detected and escaping chemicals must be removed immediately by operating staff. The WLL180T fiber-optic sensor combined with the LL3-DW02 fibers with PTFE sheath reliably reports chemicals in the collection basin to the Flexi Soft safety controller integrated in the machine.
