Introduction

Electro-Sensors, Inc. (“we,” “us,” “our,” the “Company” or “ESI”) manufactures and sells industrial production monitoring and process control systems. 

In addition, we may periodically make strategic investments in other businesses and companies, including investments that we believe would facilitate the development of technology complementary to our existing products or investments that we believe present good opportunities for the Company and its shareholders. 

ESI was incorporated in Minnesota in July 1968. Our executive offices are located at 6111 Blue Circle Drive, Minnetonka, Minnesota, 55343-9108. Our telephone number is (952) 930-0100.

Products

We manufacture a complete line of monitoring and control systems for a wide range of industrial machine applications.  The systems measure machine production and operation rates, as well as regulate the speed of related machines in production processes.

Our goal is to develop meaningful annual updates to our products.

We have a sales agreement with Motrona GmbH, a German control and interface devices manufacturer, under which we have the right to distribute Motrona products in the United States. These products interface with our products on various applications for motion monitoring.

      Speed Monitoring Systems

Our speed monitoring systems compare revolutions per minute or speed against acceptable rates as determined by our customers. These systems vary in complexity, from simple systems that detect slow-downs or stoppages, to sophisticated systems that warn of deviations from precise tolerances and that permit various subsidiary operations to be determined through monitoring shaft speed.

Our speed monitoring systems also include a line of products that measure production counts or rates, such as number of parts, gallons per minute, or board feet. These speed monitoring systems include alarm systems, tachometers, and other devices that translate impulses from the sensors into alarm signals utilized by our customers.

We have several products used in drive control systems that regulate the speed of motors on related machines in a production sequence to ensure that the performances of various operations are coordinated. The products consist of a line of digital control products for motors that require a complete closed loop PID (Proportional Integral Derivative) control. The closed loop controllers coordinate production speed among process motors and reduce waste.

      Temperature Application Products

Our main temperature applications include bearing, gear box, and motor temperature monitoring sensors.  These sensors alert an operator when the temperature exceeds or is less than a specified temperature.

     Position Application Products

We also offer production monitoring devices that include
