Tough-4 pH Direct Smart Sensor

The Turtle Tough TOUGH-4 DSS is one tough sensor.

This sensor is designed to dry out making it perfect for remote monitoring applications where sensor will be intermittently exposed to liquid.

The propriety Turtle Tough reference is specially manufactured to enable dehydration and rehydration for continuous exposure to dry conditions with only intermittent periods of wetness. Ideal for applications that have batch runs, inconsistent or restricted flows. This makes it suitable for remote access areas where sensors may unknowingly dry out.

The unique back end assembly allows sealing to be run down the length of the cable; completely isolating it from the process media and eliminating the risk of ingress or poisoning. This allows for very long life at deep submersion in even the most aggressive processes without needing to seal the sensor onto an immersion rod. The flexible cable sealing actually allows a sensor to be lowered into a tank or process directly by the cable itself, without any supporting structure. Turtle Tough have design unique and proprietary sensor guide tubes to facilitate this optional installation method, eliminating the need for heaving and cumbersome immersion rods.

The RADEL body plastics provide a both impact and chemical resistance. Utilising our proprietary toughened glass the sensor is ideal for slurries and abrasive media as well as being capable of resisting acids or fluorides that may chemically attack the glass.

The Extreme Dehydration pH Sensor is ideal for any applications where there are batch runs, limited flow process systems containing free sulphide species such as hydrogen sulphide gas (H2S), hydrogen sulphide (HS-) or sulphide ions (S2-). Any measurement where aggressive chemical cleaning is needed to remove fouling or low maintenance operation is required with minimal cleaning and recalibration.

Direct Smart Sensor Technology (DSS-MO)

Lightweight & Portable

Calibrate and configure at any location retaining all values

Portable 9V battery powered communicator to calibrate & configure DSS-MO smart digital sensors with MODBUS RTU output at any location desired while still retaining all values stored including the last calibration performed

Six values stored in non-volatile EEPROM memory

Complete installation portability & hot-swap use with the following values stored:

  • Offset calibration for temperature pH or ORP sensor
  • Offset calibration for pH or ORP sensor
  • Acidic slope for pH sensor used when reading < pH 7
  • Alkaline slope for pH sensor used when reading > pH 7
  • Factory set Sensor Serial & Item Number for traceability
  • The max & min °C in service & total time in use (energized)

Intelligent Software

The intelligent software on DSS-MO communicator auto-detects sensor type connected & loads the appropriate options such that one communicator can interface all possible types of DSS-MO smart digital MODBUS sensors

Access to REAL-TIME DATA in no time.

With the MODBUS RTU you will have access to ALL information that is available from the communicator:

  • Real-time data acquisition of measured process parameter (pH or ORP)
  • Temperature
  • All calibrations & diagnostic details about the installed DSS-MO smart digital sensor for intelligent remote management & troubleshooting capabilities

Quick disconnect cables to 1,000 meters

  • NEMA 6P & IP67 rated waterproof
  • HiQ4M & HiQ4F snap connectors for rugged field use

Offset calibrations available for ORP measurement and temperature

Input Data ranges and max resolution for pH & ORP measurements

  • pH range of -2 to +16 with 0.001pH max resolution
  • ORP range of ±1000 or ±2000mV; 0.1mV max resolution
  • Temperature range of -40 to +210 °C; 0.1°C max resolution

3 Calibration points for optimal accuracy at any pH

Perform 1-point offset anywhere in the range. Slope calibrations are automatically assigned for acidic (-2 to +7) or alkaline (7 to 16) pH ranges yielding a 3-point point overall calibration scheme with a dual slope for optimal accuracy at any pH (can be very important for batch systems).

Automatic Temperature Compensation

(ATC) for pH measurement
