TT-FB-pH Foxboro Compatible pH Sensor

The TT-FB-pH Foxboro Compatible pH Sensor is made possible by utilising our true differential pre-amplifier sensor that mates seamlessly to Foxboro analysers.  Foxboro Analysers have a long history in industrial process measurement. As a result, some of the most resilient sensors we've designed are compatible with Foxboro hardware, and virtually all our application specific sensors can be designed to interface with these analysers.

Our replacement OEM sensor for the Foxboro  product is designed as an affordable all-rounder and can be special ordered with nearly any option.  The standard double junction sensor is sulphide resistant and can be special ordered in triple junction.  The affordable and highly chemical resistant RYTON body plastic is standard, however for added physical strength and abrasion resistant RADEL or PEEK can be optioned.  This OEM replacement is not simply a substitute.  It will outlast and outperform the OEM product several times over. 20 years of evidence guarantees it.

Extreme dehydration, slurry/abrasion resistance, high HF are all options supported by this sensor.

The result is a sensor that will in all cases will outperform the OEM because of our application specific approach to improved sensor performance.  There are many good reasons why some of the biggest names in the industry are using a Turtle Tough sensors on a Foxboro Analyser, but the main reason is reliability and a lower cost of ownership.

Applications

Any process media containing free sulfide species such as hydrogen sulfide gas (H2S), hydrogen sulfide (HS-) or sulfide ions (S2-). 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.

Recommended Cleaning Schedule

If a Turtle Tough pH/ORP sensor response slows down, it is most likely the result of a fouled reference or dirty coated glass.  Cleaning should be performed as required and will vary across  applications.  See cleaning instructions.

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.
