SMART-5 pH Direct Smart Sensor

The Turtle Tough SMART-5 direct smart sensor is one tough sensor. Designed specifically to resist high velocity solids and high levels of abrasion this sensor provides unprecedented periods of survival in applications where most of our competitors literally disintegrate.

The Turtle Tough SMART-5 direct smart sensor is extremely versatile for a variety of installation methods. By utilizing?a double thickness 3/4" x 1" RADEL body, it is suitable for both immersion, submersion and valve retractable installation types. ?The RADEL body material offers excellent resistance to abrasion at an economical price, while a fast response TC is built in close to the sensing element for superior calibration accuracy in all installation types.

The real secret to this sensor is the glass. Known for its fragility, the glass sensing element is often the weakest link in sensors having to cope with high velocity solids and slurry abrasion.? Our unique and proprietary glass formulation is arguably the strongest pH glass bulb in the world and is capable of withstanding direct impact from high velocity slurries. We like to think it is 'virtually' unbreakable for it's intended use.

Fouling is another common problem with many brands of sensors, however our open geometry, coating resistant materials and our preference for high velocity (to keep the sensor clean) maintain optimal performance of the sensor within the sensibilities of a standard cleaning regime.

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

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).

Any measurement where aggressive chemical cleaning is needed to remove fouling or low-maintenance operation is required with minimal cleaning and re-calibration.

Application Difficulty Index: xx/10

This sensor is design for difficult applications with a difficulty index?up to xx/10

Maintenance FREE

Turtle Tough pH and ORP sensors are a completely sealed assembly and are sealed for life.? This provides extreme process resistance as well as a totally maintenance free sensor which greatly increases sensor life and reduces labour costs.? A Turtle Tough sensor does not contain any O-rings, washers, gaskets, or serviceable components/assemblies. It does not require refreshing or refilling of electrolyte. The only requirement is regular cleaning in accordance with our recommended cleaning schedule for your application. Regular cleaning will prolong the life of your sensor and ensure hassle free operation.

Storage

The standard shelf life for all Turtle Tough pH and ORP sensors is one year from the date of shipment. Sensors stored longer than this period may still be functional but are no longer under warranty. Sensors should be stored in a cool, dry location with the sensor tip (sensing element) oriented toward the ground.? All sensors come standard with a conditioning solution in the cap. This conditioning solution is 50% pH 4 buffer and 50% saturated potassium chloride (mixed by volume). The sensor cap should be kept tightly affixed to the sensor body and sealed with common PVC tape when the sensor is not in use. Sensors that are to be returned for shelf life warranty claim must have the original sensor cap and conditioning solution intact to be eligible for warranty replacement.

Avoiding Thermal Shock

For high temperature applications where process liquid exceeds 70?C you will prolong the life of the sensor by avoiding thermal shock. Thermal shock occurs when you rapidly change the temperature of the sensor from hot to cold or vice versa. This rapid expansion/contraction of sensor components can damage internal elements and cause micro-cracking that will accelerate the rate of deterioration. In extreme cases it will crack the sensing element causing a total failure.? To avoid this sensor should be heated or cooled slowly during removal/insertion and cleaning and calibration processes. Consult your Turtle Tough representative for techniques to avoid thermal shock.

Conditioning After Calibration

After the sensor has been cleaned, it must be thoroughly rinsed with deionised water to remove any residual cleaning reagents. The sensor can then be soaked in pH 4 buffer to recondition the pH and reference elements. Some sensors will also require conditioning in saturated potassium chloride if the reference junction has been depleted of the ions in the solid state conductive polymer (typical for clean water applications). Condition the sensor in saturated potassium chloride and/or pH 4 buffer for whatever period of time is required to achieve optimal calibration results.

Please refer to your sensor manual for correct installation, maintenance and use.
