Endress+hauser CPS31 Analog pH sensor Ceratex
Ceratex CPS31: pH Expert for Disinfection
The Ceratex CPS31 stands as the analog expert specifically engineered for precise pH compensation in critical disinfection processes. Its innovative design incorporates three diaphragms, rendering it exceptionally suitable for applications even with minimum conductivity levels. This advanced feature ensures unwavering accuracy where other sensors might falter. Its inherently low drift guarantees remarkably stable measurements, providing consistent and reliable data for sensitive operations.
Ensuring Agreeable Swimming Pool and Drinking Water
The CPS31 plays a pivotal role in maintaining the quality and safety of public and private water sources. This highly specialized sensor ensures that “swimming pool water” remains agreeable and safe for bathers by precisely controlling pH levels, preventing irritation and optimizing disinfection. Crucially, it contributes to making “drinking water” not only safe but also tastefully pleasing, by accurately compensating pH for effective chlorine disinfection.
Reliable Measurement in Low Conductivity Settings
One of the most significant advantages of the Ceratex CPS31 is its ability to deliver highly reliable measurements even in environments with challenging minimum conductivity. This is made possible by its unique configuration of three robust diaphragms, which facilitate stable ion flow and prevent measurement fluctuations. This design ensures that essential disinfection processes are never compromised by unreliable pH readings.
Minimizing Drift for Uninterrupted Stable Data
The CPS31 is engineered for exceptional measurement stability, characterized by its remarkably low drift. This crucial benefit stems from a very low level of ion depletion within its electrolyte, ensuring the sensor maintains its calibration over extended periods. This superior stability translates into less frequent recalibration, reduced maintenance, and ultimately, more consistent and trustworthy data for process control.
Specialized for Free Chlorine pH Compensation
A core application where the Ceratex CPS31 truly shines is in providing precise “pH compensation for free chlorine measurement.” Accurate free chlorine levels are paramount for effective disinfection, and the CPS31 ensures that the pH influence on these measurements is correctly accounted for. This critical function guarantees optimal disinfection efficiency in both drinking water and swimming pool facilities.
Enhanced Operational Time with Optional Salt Ring
To further extend its utility and operating lifespan, the CPS31 offers an optional salt ring. This beneficial addition significantly increases the time between maintenance intervals, especially in challenging applications or those with very low conductivity. The salt ring provides a steady reservoir of ions, further stabilizing the reference system and ensuring prolonged, uninterrupted, and accurate pH measurement.
Robust Design for Process Temperature and Pressure
Built for durability, the CPS31 is designed to operate effectively within a process temperature range of 0 to 80°C (32 to 176°F), making it suitable for a wide array of water treatment scenarios. It can also withstand process pressures from 1 to 4 bar absolute (15 to 60 psi). This robust construction, combined with its IP68 ingress protection, ensures the sensor’s longevity and reliability even under continuous operational stress.
