  • Vibrating Rod Level Switch for Liquids – VLS Switch

    Vibrating Rod Level Switch for Liquids – VLS Switch

    The Vibrating Rod Level Switch (VLS) is the perfect solution for single point level switching in free flowing solids.  For tanks, silos or hopper bins, and for a wide density range of solids from fine powders, grains to agregates. A single rod design provides the solution to tuning forks which may become blocked or bridged.

    The vibrating rod is energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics which switch the output relay after a configurable time delay. The vibrating rod level switch is the perfect solution for single point level switching in free flowing solids across a wide density range, from fine powders to grains. A single rod design provides the solution to tuning forks which may become blocked or bridged.

  • Rotating Paddle Level Switch – PLS Series

    Rotating Paddle Level Switch – PLS Series

    The paddle switch may be used as either a high or low level limit switch. It is easily mounted from above, or through a vessel wall.  A small electric motor drives a paddle which rotates freely in the absence of material. When the paddle is impeded by the presence of material, a microswitch actuates an alarm signal. As soon as the paddle is completely stopped from rotating, power to the motor is cut, thereby extending motor life. After the material level falls, the motor is returned to its normal position and the paddle begins to rotate again.

    Failsafe models use a microcontroller for self-validating diagnostics and monitor both motor and shaft rotation to detect and indicate a fault condition on the fault relay.

    The PLS Series of switches can be used with granular, pelletized, and powdered dry products. They may be used in high level applications with materials over 160 kg/m3 and low or intermediate applications with materials over 80 kg/m3.
