Electro-Sensors, Inc. began operations in 1968 in St. Louis Park, Minnesota. It was founded by James P. Slattery to serve material handling and process control applications in industrial plants. The original products included the Bin-Levetrol level sensor which sensed presence or absence of material and functioned as a high or low level control for bins or hoppers used in dry bulk material handling systems. Another core product was a speed monitor for monitoring critical shaft speeds and was used on conveyor belts, screw conveyors, bucket elevators, and similar process equipment. This speed monitor would shut off the driven equipment if proper speed was not maintained. As the company grew, other sensing technologies and products were added to monitor temperature, vibration, or position in industrial applications. These products include shaft speed sensors, shaft speed switches, bearing temperature sensors, belt misalignment devices, vibration switches, position monitors for slide gates and valves, tilt switches, motor speed controllers, and complete hazard monitoring systems for processing plants.

Electro-Sensors, Inc. consistently produces the most reliable machine monitoring sensors and hazard monitoring systems, utilizing leading-edge technology to continuously improve our products and make them easier to use. Our goal is to manufacture the industry-preferred product for every market we serve. We do this through total quality commitment, by completely fulfilling our customers' expectations.
