Pepperl+Fuchs introduces Vibracon LVL-B series vibration limit awitches. The series sensors are insensitive to material build-up, external vibration and flow noise, and they have no mechanical moving parts for maintenance-free level sensing of bulk solids materials. The switches are well suited for sensing fine or coarse-grained material such as grain, sugar, animal feed, beans, gypsum, sand, plastic granules, chalk, cereals, rice, detergents and cement. They are FM and CSA certified as dust ignition proof (DIP) for Class II and Class III, Divisions 1 and 2, Groups E-G, making them suitable for hazardous area applications. The sensor is constructed of stainless steel to eliminate abrasion issues. A plastic housing with cover sight glass makes the switch status easily visible from outside the hopper.
