How often do I need to clean and calibrate my sensor?
- How often a sensor requires cleaning and calibration depends upon:
- The process conditions and how quickly the major constituents are poisoning the sensor
- The desired accuracy for the measurement to maintain acceptable process control
- The amount of fouling or process build-up that will eventually affect sensor performance
- How well the sensor is cleaned and maintained at the specified interval (ie using the correct chemicals to decontaminate the sensor)
- Turtle Tough sensors are specifically designed to improve these maintenance requirements by incorporating the following:
- Turtle Tough sensors have very tough measurement elements that are slow to deteriorate and therefore drift is minimised.
- Turtle Tough sensors utilised open geometry designs and low fouling materials to reduce build-up and extend cleaning intervals
- Turtle Tough sensors have very resilient materials of construction to withstand harsh cleaning regimes. Strong acids, alkaline, organic solvents and abrasive mechanical cleaning can be deployed to efficiently and effectively clean sensors returning them to optimum operating condition.
General Guideline
| Drift (pH units) | TOUGH APPLICATION (ie: intensive chemical process) | MODERATE (ie wastewater) | EASY (ie clean water) |
0.1 | 3x per week | 1x per week | 1x per month |
0.3 | 1x per week | 1x per month | 1x per 6 months |
0.5 | 1x per fortnight | 1x per 3 months | 1x per 12 months |
Do I need to replace my existing transmitter? Or Will a Turtle Tough Sensor work with my existing hardware?
Yes/No. We can make a turtle tough sensor to fit most brands of transmitters. Turtle Tough sensors are made with the appropriate electronics to interface with most of the major brands such as Rosemount, Yokogawa, Endress and Hauser, ABB, Foxboro and many others. This can save significant costs in changing over instrumentation, and our turtle tough sensors will outlast the OEM sensor by several times.
Please note that some brands of transmitters do place certain limitations on the Turtle Tough sensor design. For best life and performance it is always recommended to use a Turtle Tough sensor with the Turtle Tough TX series of transmitters.
Why is it better to use a Turtle Tough TX than my OEM Transmitter?
When we make a Turtle Tough sensor TOUGH, we put a lot into chemical and physical resistance into the sensor design. This adds to the overall sensor impedance and many OEM transmitters are not designed to handle this extra impedance. As a result they may reject the sensor prematurely or display error codes when it still has plenty of life left in the sensor.
Our range of Turtle Tough Transmitters are designed to handle the high impedances of our sensors and will allow them to be used much longer than most OEM units will permit.
How can you say Turtle Tough sensors will SAVE MONEY when they are more expensive than my OEM sensor?
Indeed the unit price of a Turtle Tough probe is more expensive than an OEM equivalent. The nature of hand-making sensors and using materials and designs that meet specific application requirements is more costly. It does however produce a product that will outlast an OEM equivalent by several times over, saving a significant amount over a period of time.

Does Turtle Tough have a direct replacement for my sensor?
No. The entire success of Turtle Tough centres around our ability to custom make a sensor for your application. Providing you with a standard off-the-shelf solution is the product you already have, and this ignores the fact that your application is unique and requires its own matching chemistry to make a sensor work to its optimum. While we do have sensors that may connect to your transmitter, the materials and dimensions will not be an exact replica of what you are using. We don’t make replicas, we make sensors that work. If you tell us specifically about your application, we can match the chemistry of our build to your process requirements.
Please note if your analyser can only accept a smart digital sensor, then we can not offer you a compatible solution. Digital Sensors utilise the manufacturers proprietary signal (which belongs exclusively to them) and that cannot be copied by other manufacturers without breaking the law. Retrofitting sensors only work if your analysers can accept an analogue sensor. If you need a smart sensor solution (which is highly recommended), Turtle Tough has a wide range of hardware to choose from. You also have the choice of connecting our Smart Sensors directly to your PLC or data acquisition device without the need for a traditional transmitter.
