It provides a solid foundation for data-driven predictive maintenance and Industrial Internet of Things applications.
2. Rugged and Durable Design for Demanding ConditionsThe 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 CompatibilityThe 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).
