Product Specification

ToughSonic 14 Level & Distance Sensor
PC or Button Setup, Waterproof, Two Selectable Outputs

The ToughSonic 14 ultrasonic sensor has a maximum range of 14 feet (4.3 meters).  Like all ToughSonic sensors, it’s built for durability and ease of use in tough industrial environments. It’s fully submersible, corrosion resistant, shock resistant ultrasonic sensors are housed in 316 stainless steeland all around tough. It’s also fully configurable with  our SenixVIEW software. ToughSonic 14s include our famous “Teach” feature for push button configuration. This compact sensor is used around the world on remote liquid level systems, heavy equipment, factory automation applications and more. This is our most popular sensor.

For longer range applications or for chemically resistant sensors, please see our full line of ToughSonic and ToughSonic CHEM sensors.

Non-Contact Ultrasonic Distance & Level Measurement

ToughSonic ultrasonic sensors are built Tough with:
• 1.88 inch (48 millimeter) type 316 stainless steel housing.
• Sealed epoxy potting for wet and dirty applications.
• Ruggedized piezoelectric ultrasonic transducer, potted in place.
• Hardened ToughSonic internal electronics.
• UV resistant, potted-in, 9-wire cable.
• Short and overload protected input / output.

ToughSonic ultrasonic sensors are built Smart with:
• SenixVIEW configuration and analysis software controls more than 60 performance parameters and dozens of viewing, analysis and maintenance options.
• Multi-sensor network capable.
• Up to six simultaneous, industry standard outputs.
