The VRX series from BinMaster combines reliable vibrating probe technology with an LED status indicator for bright point-level alerts, from up close to over 100 ft. away.
VRX21 is the standard model, with a variety of customizations available to meet users’ operational needs.
VRX sensors outperform other point-level sensors in extremely lightweight, low-dielectric bulk materials. The probes measure powders, flakes, or granular bulk solids with bulk densities as low as 1.25 lb./ft.3.
Buildup-resistant blades and adjustable sensitivity make VRX a dependable choice for high-, mid-, or low-level alerts. Two sensitivity settings - high and low - reduce false alarms.
VRX sensors include a wide range of mounting options. For assistance in choosing the best top or side mounting option, contact the BinMaster team.
