SensorTech was founded in 1984 by a former Boeing instrumentation engineer and university engineering educator as well as a prominent office-technology entrepreneur. Originally named Electronic Sensors, Inc., we were established as a technology-based manufacturer of continuous liquid-level monitoring and control instrumentation.
Gradually, our sensor line expanded to include mechanical, pressure, radar, and other sensors to measure and monitor a wide range of fluids: water, oils and lubricants, fuels, industrial chemicals, coatings, slurry, and cryogenic gasses and liquids.
In the 1980s, SensorTech began providing automated alarm and remote-communications capabilities for tank monitoring. By the 1990s, we seized upon the growth in satellite and cellular telecommunications to provide an exceptional array of remote-sensing and remote-monitoring capabilities.
With the growth of the Internet, we adapted our systems to provide Internet-based screen displays and e-mail alerts, providing customers secure access to their tank level information from their computers, digital tablets, and smartphones.
Today, we focus on what we do best — IoT solutions — including sensor monitoring with remote access and actionable reporting.
