As the first transmitter to combine both optical sensors and Memosens sensors on a single platform, it enables complete measuring point setup for demanding processes such as chromatography, fermentation, phase separation, and filtration.

The transmitter’s core capability is its unique hybrid sensor combination. It accepts inputs from up to two process photometers and four Memosens sensors simultaneously, measuring up to 16 different parameters from six analytical sensors. Sensor types supported include pH, ORP, conductivity, dissolved oxygen, nitrate, turbidity, free chlorine, and ion-selective sensors. Mathematical functions allow the CM44P to calculate measured values based on multiple input values, enabling up to six “virtual” process values such as pH calculation from two conductivity values or rH value based on pH and ORP inputs.

The CM44P is especially suited for demanding analytical processes. In chromatography, combining a UV process photometer with pH and conductivity measurement ensures accurate detection of the target product and verifies buffer quality, leading to optimum product yield. The transmitter also detects the transition from product to cleaning phase, allowing optimization of cleaning and flushing cycles. In fermentation, photometer measurement with pH and dissolved oxygen helps achieve optimal growth conditions for microorganisms. For filtration, combining turbidity and dissolved oxygen measurement provides an accurate overview of the process, indicating product purity and whether oxygen has penetrated the process.

The transmitter performs diagnostics on all connected sensors and analyzers, transmitting error messages according to NE107 categories. Diagnostic functions include monitoring pH glass impedance, measuring signal stagnation, monitoring electrode condition and aging, checking overcurrent conditions, and comparing conductivity and temperature values against USP and EP specifications for pharmaceutical water.

Communication options are extensive, including 0/4…20 mA, HART, PROFIBUS DP, Modbus RS485/RTU, Modbus TCP, EtherNet/IP, PROFINET, and an integrated web server. The web server allows operators to remotely view diagnostic data, perform configurations, or access device parameters in any web browser, even via smartphone. The transmitter can be extended with an Ex module whose approvals (IECEx, ATEX, CSA) allow connection of sensors installed in hazardous areas.

The CM44P interfaces to all Memosens sensors from Endress+Hauser and other vendors. Sensor-related data stored directly in the sensor head can be accessed for analysis, mathematical calculations, and diagnostic purposes. Data can be stored in a tamper-proof database or SD card, exported to CSV, and logged with up to 150,000 entries in up to eight logbooks. All settings and logbooks are stored in non-volatile memory for retention during power failure. Memosens lab-calibrated sensors and hot plug-and-play allow fast commissioning.

The transmitter is available as a field device (IP66/67) or cabinet device (IP20), with an external display option (IP66). Housing materials include PC-FR base and DIN rail housing with EPDM seals.

Endress Hauser Digital non-glass pH sensor Ceramax CPS341D

 

The Ceramax CPS341D is a digital non-glass pH sensor from Endress+Hauser, engineered as the long-runner for hygienic applications in the food and life sciences industries. Featuring a shatterproof pH-sensitive enamel coating on a steel carrier and Memosens digital technology, it guarantees long-term stability and minimal maintenance in demanding sanitary processes.

The sensor’s construction is fundamentally different from conventional glass electrodes. The carrier material is made of steel, protected against corrosion by a special resistant, anti-adhesive enamel coating. The yellow pH-sensitive enamel is fused on the lower end in a circular shape, providing a pH-sensitive area much larger than that of a glass electrode. Because there is no internal buffer, the enamel measuring electrode is directly connected to a metal contact, simplifying the sensor design and contributing to its long-term stability.

The Ag/AgCl reference is integrated in the head of the electrode, with a conductive electrolyte connection between the electrolyte vessel, reference part, and product established via a tube and a hygienically formed ground diaphragm. The KCl electrolyte is supplied in sterile PE bottles placed in a stainless steel pressure vessel. The pressure inside the electrolyte system must always be kept above the process pressure. Thanks to this sophisticated construction, the Ceramax CPS341D shows almost no drift or aging, and in most applications, annual calibration is sufficient.

The sensor is suitable for Clean-in-Place and Sterilization-in-Place processes, making it ideal for hygienic applications. It resists extreme corrosion in strong acids and is not affected by organic solvents or proteins. The glass-lined steel carrier provides mechanical stability against abrasive substances and turbulent flow from agitators, and the sensor can be installed at any orientation, even upside down. The Ceramax is installed directly in pipes or tank nozzles without the need for an assembly.

The CPS341D is used across a range of applications including food production with highly pasty media, beverage production and filling, quality control, pharmaceutical industry, biotechnology, fermentation, and water treatment. Its non-glass, shatterproof design makes it particularly valuable where glass breakage poses a contamination risk, and its large pH-sensitive surface ensures reliable measurement even in viscous or challenging media.

Memosens digital technology provides non-contact, inductive signal transmission that eliminates moisture and corrosion issues, enables laboratory pre-calibration, and stores calibration data and sensor history directly in the sensor head for predictive maintenance. The sensor is precalibrated when delivered and combines maximum process and data integrity with simple operation.

The sensor features an integrated NTC 30 kΩ temperature sensor for automatic temperature compensation. It has a diameter of 12 mm (0.47 inch) and a shaft length of 120 mm (4.72 inch), with different hygienic process connectors available. The connection uses a contactless, inductive, digital connection head with Memosens technology, rated IP68 for ingress protection. The sensor is compliant with FDA and EU 1935/2004 regulations for food contact materials.

The Ceramax CPS341D delivers reliable, shatterproof pH measurement for hygienic food and life sciences applications, combining enamel-based non-glass technology with Memosens digital capabilities for maximum process integrity and minimal maintenance.
