ToughSonic® Ultrasonic Sensors.  Tough. Smart.

ultrasonic sensors ToughSonic familySenix 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). Thousands are in use worldwide in many industries in both indoor and outdoor applications.

The Senix ToughSonic and ToughSonic CHEM product lines represent more than 25 years of ultrasonic innovation and engineering. Senix was the first company to introduce computer-controlled ultrasonic sensors in 1990 and we have been making them tougher and smarter ever since. Senix ultrasonic sensors are designed to handle even the most challenging liquid and distance measurement applications and environments. We make them tough and smart and we back them up with outstanding customer service and support.

What our customers say…

Cable One buys ultrasonic sensors from Senix

Works like a charm! The whole apparatus: sensor, SenixVIEW, and the ASCII output are all working beautifully.



Tough Construction

  • Rugged electronic circuitry designed and engineered specifically to meet Toughsonic standards for power, control and longevity.
  • The highest quality, ruggedized piezoelectric ultrasonic transducers.
  • Electronics, transducers and cables fully potted in an epoxy resin chosen for its exceptional strength and unique acoustic properties.
  • 316 Stainless steel or Kynar® (PVDF) housings designed to stand up to the most demanding environments.

Smart Features

  • SenixVIEW™ Software
    Every ToughSonic® sensor comes with SenixVIEW sensor configuration and analysis software. SenixVIEW allows you to customize over 60 configuration parameters, dozens of output combinations, networking, data logging and reporting features all accessible through an intuitive graphical interface. SenixVIEW gives you complete control over your ultrasonic sensors.
  • Outputs
    ToughSonic® sensors have up to six simultaneous outputs that are fully configurable using SenixVIEW software. In addition to RS-232, RS-485 or ASCII serial data output, there are three analog outputs and two solid state switches.
  • “Teach Feature”
    Many ToughSonic® models can be configured using a simple pushbutton “Teach” feature. We invented this feature in 1990 and it continues to be the easiest sensor control mechanism available.

Common Sensor Applications


LIQUID-LEVEL-84-PX-Square   Liquid Level

Our sensors are commonly used to measure liquid level in tanks, streams, channels and weirs. We measure benign, acidic, caustic, and hazardous liquids in demanding indoor and outdoor environments. Read more on liquid level applications.

   Object Detection

ToughSonic sensors detect the presence, absence or position of an object or person. We use high sensitivity transducers and advanced control algorithms to detect  small objects and even weak-reflecting materials such as clothing and woven and non-woven materials. Read more on object detection applications.

   Distance Measurement

ToughSonic sensors don’t just detect an object, they measure the distance to that object. Distance ranging permits different responses depending on whether the object is approaching, stopped, or retreating. The speed at which objects are moving can also be measured. Read more on distance measurement applications.
