E+H Memosens CPS11E Industrial Digital pH Sensor & Transmitter

In industrial process control and environmental water treatment, traditional analog pH electrodes often fail prematurely due to junction clogging, humidity-induced signal loss, and frequent field calibration demands. Our Industrial Digital Glass pH Sensor engineered with Memosens technology overcomes these operational challenges by combining robust glass electrode mechanics with an intelligent digital communications platform.

By executing analog-to-digital signal conversion inside the sensor head itself, measurement data is transmitted inductively across an electromagnetic interface to the transmitter. This completely seals the electrical connection from moisture ingress, chemical fumes, and cable degradation, guaranteeing stable long-distance data transmission without signal drift. Furthermore, the combination of a high-purity glass membrane, a dirt-repellent annular PTFE junction, and a specialized gel electrolyte provides exceptional stability across broad pH and temperature ranges. The internal microprocessor automatically logs key operating parameters, calibration history, and temperature extremes, enabling predictive maintenance strategies and allowing technicians to pre-calibrate sensors in clean laboratory environments before performing quick hot-swaps in the field.

FAQ
Q1: What are the main benefits of Memosens digital pH sensors over traditional analog sensors?

A: Memosens sensors store calibration data and process history inside the sensor head. They transfer data inductively via electromagnetic signals, completely eliminating cable moisture/corrosion issues and allowing plug-and-play field installation using pre-calibrated sensors from the laboratory.

Q2: Can this sensor directly replace Endress+Hauser CPS11E / CPS11 digital pH sensors?

A: Yes, our digital pH sensor is designed with standard Pg 13.5 process threads and Memosens protocol compatibility, making it an ideal drop-in cost-effective replacement for existing systems without modifying piping or installation fittings.

Q3: How often does the pH sensor need calibration?

A: Calibration frequency depends on process temperature, pH range, and chemical aggressiveness. Thanks to the clog-resistant PTFE ring junction and gel electrolyte, calibration intervals are significantly longer than standard glass electrodes. The built-in diagnostic function alerts operators when calibration or replacement is required.

Q4: Do you offer custom insertion lengths, cables, and OEM branding for process instrumentation distributors?

A: Absolutely. As an automation instrument manufacturer in China, we support OEM/ODM services including custom probe lengths, private labeling, modified process connections, and complete liquid analysis system bundles (transmitters, flow fittings, and accessories).
