Product Description

MOBREY SMA1 Vibrating Rod Level Switch

The Mobrey SMA1 is a robust and reliable vibrating rod point level switch designed for detecting high or low levels of bulk solids, powders, and granules. Its operating principle is based on a vibrating rod that changes its vibration frequency when covered by the process material. This change is detected by the electronics, triggering an output signal. The SMA1 is known for its simple installation, maintenance-free operation, and insensitivity to material build-up on the probe, making it suitable for a wide range of industrial applications including silos, hoppers, and bins in industries like food & beverage, plastics, chemicals, and building materials.
