Improve process uptime with reliable pH measurement 

Endress+Hauser recently helped a catalyst manufacturer replace its pH measurement instrumentation when the short life span became a risk and a drain on resources. The current pH probes were being replaced every batch, which was expensive, a strain on productivity and an increased safety risk. 

Endress+Hauser recommended Memosens sensors which are designed to operate in heavily soiled media and can withstand fluctuating process conditions.

The previous manufacturer’s conventional sensors were not sustaining accuracy in the alkaline process environment for more than one batch. At that point, the pH measurement began deviating from the specified tolerance and required either sensor calibration or replacement. The team opted to replace the sensors as needed, but that was still very costly and time consuming. It was also an increased risk to personnel who had to remove the sensor and risk being exposed to the chemical process during each replacement.

Memosens sensor technology

Knowing the company needed sensors with a longer service life, a simpler maintenance process, and the ability to function in heavily soiled media, our team suggested a Memosens pH sensor

Designed to resist strong acids and bases, the Memosens sensor produced results that were not affected by the strong process conditions because unlike conventional probes, Memosens sends the pH measurements inductively to the transmitter as a digital signal.

The catalyst manufacturer implemented the Memosens pH sensor and saw the service life extended from one batch to ten batches. With extra batches of service, they were able to increase production uptime, lower maintenance cost, maintain the product quality and increase overall process safety.
