Tough. by Design

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 serial data-only applications.

Smart. Engineering

ToughSonic sensors have the smarts to:

  • easily connect with your equipment
  • includes both analog and switch outputs
  • communicates by serial data
  • optimize the sensor to the application
  • create stand-alone functions
  • 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


Flexible. Outputs

connect to

  • PLCs, motor drives, displays, PCs – you name it!
  • Universal: one sensor = many applications
  • 5 simultaneous industry standard outputs that are configured using SenixVIEW software
  • Analogs: 0-10 VDC, 4-20 mA sourcing and 4-20 mA sinking
  • Switches: Two, configurable as either sourcing (PNP) or sinking (NPN)
  • 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 RS-485 networks
  • Serial data-only models are also available

Connected. SenixVIEW Software

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
  • Built-in data logging, graphing, exporting and statistics facilities
  • Save & retrieve setups for maintenance and sensor cloning

Sensor Adjustments Give You More Control 

  • Analogs: Slope, distance endpoints, analog value limits
  • Switches: Setpoints, hysteresis /window features, time delays
  • All Outputs: Power-on, loss of echo, loss of SYNC responses
  • Serial Data: Communications and SYNC modes and functions
  • Measurements: Temperature compensation, sensitivity, data filters, measure rate, gain settings and data processing filters
  • Adjustments: Stored in sensor memory even when power is off
