Smart Sensing, Precise and Reliable: The E+H CPS11E Digital pH Sensor

In process industries such as water treatment, chemicals, and pharmaceuticals, precise pH measurement is a critical factor for ensuring product quality, maintaining process safety, and controlling environmental compliance. Xi'an Xinyi Instrument Technology Co., Ltd. proudly presents the E+H (Endress+Hauser) CPS11E Digital pH Sensor. This electrode, featuring Memosens 2.0 digital technology, is specifically designed for process water, industrial wastewater, and various standard applications. With its wide measurement range (pH 0-14), pressure resistance up to 17 bar, IP68 protection rating, and ATEX/IECEx explosion-proof certification, it provides a measurement solution combining high precision, long lifetime, and intelligent management for a broad spectrum of media, from pure water to strong acids and bases.

1. Advanced Memosens 2.0 Digital Technology, Enabling the Industrial IoT
The core innovation of the CPS11E lies in its integrated Memosens 2.0 digital communication protocol. This technology digitizes the sensor's raw signal internally at the probe, completely eliminating potential issues like interference, ground loops, and poor contact that can occur with traditional analog signal transmission over long distances. More importantly, Memosens 2.0 can store extensive calibration data and process logs directly within the sensor, enabling revolutionary workflows such as plug-and-measure and laboratory calibration. It provides a solid foundation for data-driven predictive maintenance and Industrial Internet of Things applications.

2. Rugged and Durable Design for Demanding Conditions
The sensor features a gel-integrated electrode design for robust construction. Its core, a large-area, dirt-repellent PTFE junction, effectively prevents media contamination, significantly extending the sensor's service life. A specially designed long diffusion path or ion trap effectively prevents poisoning of the reference system, ensuring stable operation even in harsh media containing sulfides or proteins. With an overall protection rating of IP68 and resistance to process pressures up to 17 bar, it easily handles challenges from high temperature, high fouling, and high pressure.

3. Wide pH Measurement Range and Excellent Compatibility
The standard CPS11E covers a pH 1-12 range, sufficient for most water and wastewater applications. For special applications,options are available: Class B range (pH 0-14) for strong acid/alkaline environments; and Class C range (pH 0-10) with special glass electrodes resistant to media containing hydrofluoric acid, such as etching baths in the semiconductor industry. This adaptability enables its widespread use in diverse applications, from boiler feedwater (low conductivity) to chemical reactors (highly corrosive).
