Tough. by Design
The ToughSonic name says it all:
- Injection moulded PVDF (Kynar®) for superior chemical resistance
- Ruggedized piezoelectric ultrasonic transducer, potted in place
- 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) ∗
Injection moulded PVDF (Kynar) for superior chemical resistance
Kynar® is a registered tradename of Arkema Corporation
∗ Measurement is unreliable when submersed
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
- 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
