Senix ToughSonic and ToughSonic CHEM product lines represent more than 30 years of ultrasonic innovation and engineering. Senix ToughSonic® ultrasonic sensors measure level and distance through air using ultrasonic sound waves, often replacing unreliable mechanical devices. They provide high reliability and fast, non-contact measurements at distances up to 50 feet (15.2 meters). ToughSonic ultrasonic sensors are designed to handle even the most challenging liquid and distance measurement applications and environments. ToughSonic sensors are found on remote monitoring stations from the Australian outback to Alaskan oil fields. When an ordinary sensor just won’t do, you need a ToughSonic.
