Much of our work has involved sensors and transducers, instrument design and applications. This page is a labor of love: sensor technology intrigues us. We’ve learned a lot over the years and are still learning.

Most sensor users are not electronic designers but rather are people who design, program and apply sensors to robotics, automotive, aerospace, military, industrial and other applications. Our hope is to make sensor technology understandable. We’ll be writing for the user, not the researcher or sensor designer. No calculus, theoretical physics or the like.

We’re starting small, growing over time. Come back and visit us often. We’ll be adding more info periodically as time permits.

Temperature – Which Sensor is Best?

Thermocouple? Resistance thermometer (RTD)? Thermistor? Silicon sensor? Each has its own advantages and limitations. The choice depends on your needs and applications. This white paper examines and compares them to help you understand and choose.

Ultrasonic Leak Detection

Pressurized gas leaks emit an audible high-frequency hiss but have even more energy at ultrasonic frequencies. Small leaks give off detectable ultrasound long before they become large enough to hear. Ultrasonic leak detectors specifically respond to ultrasonic emissions, ignoring audible sound. Because of this, leaks can be “heard” at a distance, even in noisy industrial environments.

This white paper, based on a project done years ago, explains how they work and how they are used.
