Ceraliquid CPS41

Summary

Product identification

Ceraliquid CPS41D and CPS41 pH electrodes, digital with Memosens technology, and analog.

Application

Designed for process engineering with ceramic diaphragm and KCl liquid electrolyte. Optionally available with integrated temperature sensor. Suitable for media with very low conductivity or a high proportion of organic solvents or alcohol in industries including chemical, organic chemicals, power stations, food, and laboratories. Features ATEX- and FM-approval for use in hazardous areas.

Benefits include:

• KCl liquid electrolyte, enabling use with very low conductivity values (≥ 0.1 μS/cm).
• Ceramic diaphragm with specified KCl flow rate.
• Can be used up to 11 bar (160 psi) abs. pressure if counterpressure is applied.
• Poison-resistant due to a separate reference capillary.
• Suitable for CIP / SIP.
• pH membrane glass for applications involving steam sterilization.
• Available in four lengths: 120, 225, 360 and 425 mm.
• Optional integrated Pt100, Pt1000 temperature sensor for analog sensors or NTC30K for digital sensors.

Memosens technology advantages:

• Maximum process safety via non-contact, inductive signal transmission.
• Data security through digital data transmission.
• Easy to use with sensor data saved in the sensor.
• Enables predictive maintenance by recording sensor load data in the sensor (Memobase Plus CYZ71D).
