Safer food production with glass-free pH sensors from Endress+Hauser

Food manufacturing applications demand the highest standards of hygiene to ensure the best quality final products. Breakable glass pH sensors pose a contamination risk, which is where glass-free pH sensors like Endress+Hauser’s Memosens CPS77D ISFET pH sensor can play a significant role in the safe production of food products. In this article, PIF takes a closer look at the Memosens CPS77D to give you a flavour of its best attributes.

Improved CIP stability in hygienic applications

Producing food of consistently high quality requires the use of modern measuring technology. The use of pH glass sensors, which are commonly deployed for pH measurement, is not always the safest or most efficient choice, since glass breakage can contaminate entire production batches.

Endress+Hauser’s Memosens CPS77D ISFET pH sensor eliminates the risk of product contamination and can withstand more CIP cycles than any other ISFET pH sensor ever before.

Memosens CPS77D increases plant safety and availability

The Memosens CPS77D is perfectly suited to pH measurement in hygienic and sterile applications in the food and beverage and life science industries, where the use of glass sensors is avoided. The sensor features an unbreakable PEEK shaft and eliminates the risk of product contamination due to glass breakage ensuring high product quality.

This innovative glass-free pH sensor can outlast at least 25 CIP cycles and has therefore significantly improved CIP stability compared to conventional ISFET pH sensors. It delivers stable and reproducible measured values, even after sterilisation and autoclaving up to temperatures of +135°C.

Glass-free ISFET pH sensors built for hygienic applications

Endress+Hauser’s Memosens CPS77D ISFET pH sensor is perfectly equipped to meet the strict demands of hygienic applications. Thanks to its new design, with an increased chip surface, it is even easier to clean than its predecessor. It comes with all the usual hygiene approvals for the food and life science industries and is TSE-/BSE-free. Its bacteria-proof reference with contamination-resistant gel guarantees stable measurements, and its microporous ceramic diaphragm delivers maximum bacteria tightness.

The Memosens CPS77D is the digital specialist for hygienic applications. Its bacteria-proof reference with contamination-resistant gel guarantees stable measurements. The sensor is sterilisable with hot steam, autoclavable, and features an unbreakable PEEK shaft that assures the highest product safety. The Memosens digital technology combines maximum process and data integrity with simple handling. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.

Features and benefits of the Memosens CPS77D

The Memosens CPS77D ISFET pH sensor offers the following benefits:

• Unbreakable for highest product safety.
• Certified biocompatibility.
• Suitable for hot steam sterilisation and autoclaving.
• Low maintenance thanks to long calibration intervals.
• Six times higher CIP stability compared to conventional ISFET pH sensors.
• Optional Pharma CoC available.
• Maximum process safety through non-contact inductive signal transmission.

The Memosens CPS77D is designed for hygienic and sterile applications in the food and beverage, life sciences, and biotechnology sectors. For more information about the Memosens CPS77D, or any other Endress+Hauser products, visit www.uk.endress.com/en.
