Sensor for TOUGH Applications – High Chemical Resistance

The TOUGH series sensors are an excellent choice for most industrial applications. The solid state reference is low maintenance and offers long lasting performance, while the RYTON body plastics are extremely resistant to chemical attack. The tough glass offers excellent performance across a wide pH range and reduces the expense of costly breakages. The TOUGH Series sensors share a common chemistry and are available in immersion, submersible and inline configurations.

Direct Smart Sensors (DSS) with Digital MODBUS RTU Output


Turtle Tough’s range of Direct Smart Sensors (DSS) are equipped with an on-board microprocessor which is capable of processing measurement data and providing a feature rich digital MODBUS RTU output directly from the sensor. This enables the sensor to be directly interfaced with any MODBUS compatible data acquisition device, such as a PLC, RTU or data logger. Direct connectivity eliminates the need to interface with a traditional intermediary controller or analyser and provides unprecedented communication and control directly with the sensor.

Process more than a dozen parameters with Direct Smart Sensors including:

  • Measurement type
  • Calibration data
  • Raw and calibrated process values
  • Max/min temperature
  • Baud rate
  • Node
  • Serial number...

As well as useful service information such as the number of days in use. These values can be intelligently integrated into your data acquisition system to achieve a very sophisticated level of analysis and control.


Why is this different?

Smart onboard data processing presents us with a number of unique advantages that are not possible with a traditional sensor and transmitter configuration. This includes:

  • The ability to interface directly to modern PLC controllers and data acquisition systems
    • Utilise existing powerful architecture; or
    • Utilise factory supplied custom programmed PLC’s, Transmitters & Controllers
    • Access data remotely through both wired and wireless networks

  • The ability to eliminate the cost of a mating transmitter where a local display is not necessary
    • Intelligent management of sensor calibrations and service life cycle
    • Calibrate sensors offline in the laboratory or workshop
    • Offset calibrations can be done remotely with the sensor left in service
    • Accurately monitor service intervals and calibration history

About the technology

Turtle Tough’s DSS technology is supported by comprehensive documentation. Our software allows users to access all user adjustable parameters, analytic data, calibration functions as well as sending fully compensated high-resolution process values. Sensor analytics enable operators to schedule proactive maintenance and provide accurate and timely information on the process. The Modbus RTU protocol has been specifically chosen as it is an open standard that creates an open and collaborative environment for process automation and liquid analysis. This provides a level of connectivity and integration that is not possible with closed architectures and proprietary platforms that force vendor lock-in.


TURTLE TOUGH DIRECT SMART SENSORS (DSS) are fully supported by a range of factory hardware solutions including SMART Analysers, Handheld Field Communicators, PC Communication tools and field implementation devices such as junction boxes, extensions leads and power supplies. This ecosystem provides a complete solution of reliable connectivity and sensor management.

TURTLE TOUGH sensors may also be directly interfaced with end user hardware via the MODBUS RTU protocol. Integrating sensors directly into your industrial network requires a moderate to high level of onsite expertise in system integration, and should not be undertaken by anyone without the requisite experience. We suggest you read the sensor implementation guide carefully to understand the full scope and requirement for installation, because:

  1. Turtle Tough Pty Ltd and their representatives can provide only limited factory support when integrating sensors into 3rd party hardware.
  2. Product support is limited to the information provided in our field implementation notes and guidelines.
  3. Turtle Tough and their representatives are unable to provide support on 3rd party hardware or provide troubleshooting on equipment not supplied by us. We are unable to warrant the performance or compatibility of our product with 3rd party hardware or software. If you intend to integrate the sensor directly with your own hardware we highly recommend the following:
  • Read the Field Installation Guide and Sensor Implementation Guide.
  • Purchase a handheld field communicator (HFC) from Turtle Tough. This stand alone device, self powers the sensor and provides complete diagnostics and communication. The HFC allows us to independently test and verify the sensor performance, independent of your system or hardware and is the single fastest way to rule out any sensor performance issues and be able to identify field installation problems.
  • Alternatively, you may purchase a windows PC interface box. Once again, this factory supplied and tested component will ensure reliable communication with the sensor and it can be tested independently of your system.

Please note that our quick connect plugs my never be cut or removed from the sensor. This will immediately void warranty. Only use Turtle Tough factory interface leads or panel mount connectors to interface with your hardware.
