  • The economical Soliswitch FTE31 is a paddle switch for point level detection in bulk materials. Its robust polymer housing and compact design makes it an ideal sensor for full, empty and demand alarm in applications with bulk solids. The optimized materials make the unit outstandingly robust and therefore suitable for use in dust explosive areas.

    • Reliable and economical paddle switch
    • Highest safety standard for dust-explosion-hazardous areas
    • Diverse instrument designs for use under different application conditions
    • Slip clutch prevents impact on paddle
    • Ingress protection to IP 65 / NEMA 4x / Type 4x for optimum safety in the process

    The universal point level switch FTE31 is used as a full, empty and demand alarm on silos containing solids. Its construction and materials make the unit suitable for use in the food industry. The unit is suitable as a level limit switch in dust-explosion-hazardous areas.

    Typical applications are level detection in: Cereals, sugar, cacao, animal feeds, washing powders, chalk, dry plaster, cement, granulates, wood chips
