Field of application

Memosens CPS77E is the expert for hygienic applications. Its bacteria-proof reference with highly stable gel guarantees reliable measurements. The unbreakable sensor is sterilizable with hot steam, autoclavable and assures highest product safety. CPS77E features Memosens 2.0 digital technology, offering extended storage of calibration and process data for predictive maintenance. The sensor resists moisture and enables lab calibration, enhancing process integrity and increasing process uptime.

Hygienic and sterile applications:

Food & beverage industry
Life sciences
Biotechnology

With all relevant approvals for hygienic applications such as EHEDG, 3A, EU1935/2004, USP 87/88.

Benefits

Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
Unbreakable PEEK sensor body ensures highest product safety where glass breakage is intolerable.
With its certified biocompatibility and pharma compliance (optional Pharma CoC), the sensor protects the quality of your products.
The sensor is suitable for hot steam sterilization and autoclaving offering long-term stable measurements.
Low maintenance: ISFET technology is insensitive to temperature variations and shows virtually no acid or alkaline errors, allowing for long calibration intervals.
Six times higher CIP stability compared to conventional ISFET pH sensors ensures a longer lifetime even when the sensor is exposed to cleaning in place.
Maximum process safety: Non-contact inductive signal transmission eliminates all problems due to moisture or corrosion.

Videos

The pH-value of a liquid can be determined using the potentiometric measuring principle. This video shows how this measuring principle works.
Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
