Non-Contact Ultrasonic Distance Ranging

Senix ToughSonic® Ultrasonic Sensors measure distance to target objects or materials through the air using “non-contact” technology that does not touch or damage the target. They are easy to use and reliable, and used in hundreds of applications around the world in all industries.

For liquid level measurement please see our Tank Level Applications or Water Monitoring Applications.

Hydrofoil & Nautical Application Stories

The Sensors

Whether used indoors or out, ToughSonic® sensors can take abuse. Solid state electronic components are epoxy potted into stainless steel housings, and there are no mechanical parts to break. IEC compliant electrical interfaces are protected from reversed connections and over-voltages.

These distance measurement sensors connect with all common types of automation and telemetry equipment. Applications range from simple analog connections to sophisticated multi-sensor data networks. Our sensors are cost effective because flexible connectivity is embedded in the sensor’s software – power that you can unlock with the SenixVIEW PC software included with every sensor. Push-button “teach” is also included in many models.



  • Type 316 stainless steel housings
  • Sealed epoxy potted construction
  • Ruggedized piezoelectric ultrasonic transducers
  • Liquid tight IP68 immersion rating
  • IEC compliant electrical interface protection
  • Hardened ToughSonic internal electronics
  • UV-resistant, potted-in cable
  • CE compliant



  • Multiple simultaneous outputs: analog, switch and serial data
  • Adjust, optimize and manage setups with SenixVIEW PC software
  • Connect remotely to, and work safely with sensors embedded in an application
  • Filters, timing, initialization and lost target features to optimize performance
  • RS-232 or RS-485 serial data options
  • RS-485 multi-drop addressable networks
  • Multi-sensor synchronization eliminates cross-talk
  • Quick sensor duplication without re-calibration
  • Push-button “teachable“



A wide range of materials can be measured, including hard or soft, colored or transparent, flat or curved. Maximum range depends on target size, shape, orientation and sound absorption.Targets

Marine & Hydrofoil Vessels

America’s Cup Sailboat Racing

Senix ToughSonic sensors show their mettle in the rough and tumble environment of America’s Cup racing. Oracle-BMW racing first used our sensors for their 2013 cup win. As Oracle Team USA Data Analyst and Instrumentation Engineer, Jose Luis Vela commented, “We drive the boat based on sensor data. The foiling requires real-time information that is fast and completely accurate. We selected Senix ultrasonic sensors after extensive testing in a variety of high-speed marine conditions.” Oher teams have since adopted Senix sensors, including the 2017 Bermuda winner, Emirates New Zealand.

Hydrofoiling Electric Speedboat

One of Sweden’s hottest tech startups, Candela Speedboat, uses Senix ToughSonic 14 sensors for height inputs to an automated control system to manage the boat’s takeoff, cruise and landing. Founded in 2014 to build an electric boat comparable to gas power the Candela Speed Boat is truly a first in electric vehicle design. Built from 100% carbon fiber and weighing 1300 kg (2866 lb) the craft is powered by a 40 kWh lithium ion battery and 55 kW motor to achieve a maximum speed of 30 nautical knots and a range of over a 50 nautical miles. The company produced it’s first few production boats in 2018 and demonstrated the boat at Sweden’s first electric boat show in Stockholm in May 2019.

Solar Powered Boat Races

The TU Delft Solar Boat Team consists of 20 to 25 students from Delft University of Technology. The team designs and builds a new solar-powered hydrofoil boat every two years and races in the biennial Dutch Solar Challenge, the World Cup in solar boat racing. The previous Solar Boat team finished an impressive third at the Solar Cup in Monaco in July, 2015. The boat unveiled this week will begin sea trials in April in preparation for the Dutch Solar Challenge world championship this summer. See a couple of the current team members describe the boat design process in this short video:


Sensor Outputs & Interfaces

SenixVIEW Software
SenixVIEW Software

The ToughSonic General Purpose and ToughSonic CHEM product lines all have multiple analog and switch outputs compatible with most industrial equipment, plus a serial data communications interface for SenixVIEW software setup or user applications.

Analog outputs can be proportional to tank level or volume. Switch outputs can control pumps and valves, or indicate low or high alarm conditions. Simple level controls can be created with only a sensor and an external relay option. Outputs are user-configured with SenixVIEW setup software. Setups are permanently stored in the sensor, and can be saved and duplicated in other sensors without re-calibrating. Some models have 5 simultaneous outputs while others have 2 SenixVIEW selected outputs. All sensors have a serial data interface, and all outputs operate concurrently.
