Why use automated systems for a pH loop?

Why use fully automated systems for a pH measuring point? Everyone who has pH measuring points in their plant knows that cleaning and calibration are part of the normal, but time-consuming maintenance work. Save yourself this time & read more.

The other day my wife came home with one of those automatic vacuum cleaners that run on demand and docks itself when finished. I never used to think of vacuuming as a difficult task to accomplish. In fact, it was a simple part of our regular household chores. With automation, the vacuum can run on a fixed schedule, when we are not home, and clean the floor properly without any effort on our end. I am surprised how much time I have saved by automating a simple part of our household maintenance.


Time Savings with Automated Cleaning and Calibration 

Anyone who has pH loops in their plant knows that cleaning and calibration are part of the normal maintenance required for operation. On a regular basis, you must clean and calibrate each sensor in the facility. Although plant personnel may not look at the cleaning and calibration of their pH loops as a difficult task, they could save a great deal of time by automating this simple part of plant maintenance.


Automated pH systems allow for complete customization of the cleaning and calibration process. You have the option to set recurring schedules for cleaning and/or calibration frequency; just like with the automated vacuum cleaners. Based on your schedule, the system will retract the probe from the process and complete pre-programmed cleaning or calibration. In addition, you can clean or calibrate on demand at any time.

The number of individual loops in the facility dictates how much time and energy the cleaning and calibration process takes. Without automated systems, plant personnel must manually clean and calibrate each pH loop. We shouldn’t underestimate how much an individual’s time costs. This is especially true if they must go to multiple pH loop locations to perform maintenance. The automated system allows for the maintenance of the pH loops to happen independently and enables maintenance personnel to focus on other tasks. Automated systems consistently and correctly clean and calibrate sensors every time.


Safety in the Process Unit

There’s also a safety aspect that we should consider when performing maintenance in the process units of plants. Minimizing plant personnel’s time in the process units helps to prevent the possibility of accidents. In addition, depending on what the facility is manufacturing in the unit, it might be important to minimize or completely prevent exposure.



Running the vacuum cleaner or performing pH calibrations are tasks that are easily incorporated into our normal household or plant maintenance schedules. Many of us perceive these types of tasks as simple and they become part of our normal routine. However, they still consume a great deal of our time. In a plant environment, we must consider the safety concerns related to performing maintenance. Increased time in the process units increases the chances of exposure or accidents. Task automation, previously done manually, saves time, reduces the costs associated with having to perform them, and increases the safety of the personnel performing those tasks.

I am still trying to figure out what to do with the time saved by my automatic vacuum cleaner. What are you going to do with the time you are no longer spending on cleaning and calibrating pH probes?
