Tough. Construction
These rugged, compact ultrasonic sensors inspired the “ToughSonic” name. They are our flagship products with heavy duty electronics epoxy potted into type 316 stainless steel housings, with permanently attached cables and ruggedized piezoelectric transducers. ToughSonic sensors are found on remote monitoring stations from the Australian outback to Alaskan oil fields. They are installed on heavy construction and farm equipment, and in some of the harshest factory environments. When an ordinary sensor just won’t do, you need a ToughSonic.

The ToughSonic name says it all:

  • Type 316 stainless steel housing (except PVC model)
  • Ruggedized piezoelectric ultrasonic transducer
  • Hardened & protected solid state electronics
  • UV resistant, potted-in, PUR-jacketed cable
  • All epoxy-potted for wet or dirty applications
  • Short and overload protected outputs
  • IP68 ingress rating (submersible)

Type 316 stainless steel provides superior corrosion and chemical resistance, resists pitting, and is often applied in salt water environments.

Sensors can be assembled with custom cables or connectors. Serial data-only models are available for remote monitoring and other digital-only applications.


ToughSonic sensors have the smarts you need…

  • to easily connect with your equipment
  • to communicate digitally
  • to optimize the sensor to the application
  • to create stand-alone functions
  • to duplicate applications without re-calibration

Senix invented PC-configurable “smart sensors” in 1990 and has improved them ever since, giving you get the benefits of years of continuous improvement!

  • Ready out of the box but fully adjustable with SenixVIEW software (included)
  • Connect to a PC serial port or use our USB setup kit
  • Wiring and mounting accessories available


Any connection you need…

  • to PLCs, motor drives, displays, PCs – you name it!
  • Universal: one sensor = many applications
  • 2 simultaneous industry standard outputs that are selected using SenixVIEW software
  • Output #1: 4-20 mA sourcing, or PNP/NPN switch
  • Output #2: 0-10 VDC, or PNP/NPN switch
  • All configurable to the application’s needs

PLUS EVERY ToughSonic Ultrasonic Sensor has serial data for SenixVIEW setup or user application:

  • Choose RS-232 or RS-485 by sensor part number
  • RS-485 recommended unless RS-232 is required
  • Multi-sensor Modbus-addressable RS-485 networks
  • Serial data-only models are also available


Send liquid levels wirelessly and view them on a LAN    or in the cloud using our new AirWire LoRa transmitter:

  • From in-plant or outdoors up to miles away
  • Low energy, battery powered transmitter
  • Tank levels or outdoor bodies of water
  • Receive high & low level alerts
  • No subscription service charges
  • For low data rate applications
  • No conduit or power required


SenixVIEW is included at no charge, runs on a Windows PC and connects to sensors via a serial data port. Our Setup Kits provide everything needed to connect through a USB port, including power supply, sensor-PC interface and cables. SenixVIEW is not required but adds powerful configuration, test and management capability.

  • View sensor measurements graphically in several different ways
  • Over 60 user-adjustable parameters
