Electro-Sensors, Inc. engages in the manufacture and distribution of industrial production monitoring and process control systems. It manufactures and sells various monitoring systems that measure actual machine production and operation rates, as well as systems that regulate the speed of related machines in production processes. The company's speed monitoring systems include a line of digital products that translate sensor impulses from its production monitoring systems into digital readouts indicating production counts or rates, such as parts, gallons, or board feet. Its speed monitoring systems also comprise alarm systems, tachometers, and other devices that translate impulses from the sensors into alarm signals, computer inputs, or digital displays. In addition, the company offers production monitoring devices, including tilt switches, vibration monitors, and slide gate position monitors; digital control products for motors that require a complete closed loop proportional integral derivative control; and closed loop controllers, which coordinate production speed among process motors and reduce waste. It serves grain, feed, biofuels, food processing, chemicals, agricultural, mining, utility, forest products, steel, tire, glass, and electronics industries. The company sells its products through internal sales staff, manufacturer's representatives, and distributors to manufacturers, original equipment manufacturers, and processors in the United States, Mexico, China, Canada, Chile, Bolivia, Colombia, Malaysia, Singapore, Great Britain, Australia, Egypt, El Salvador, Guatemala, Korea, Puerto Rico, Taiwan, and Turkey.
