工作原理
Sensing electrodes operate on electrochemical or physical transduction principles. In electrochemical applications, they facilitate redox reactions or ion exchange at the electrode-electrolyte interface, generating measurable electrical signals proportional to analyte concentration. In physical sensing, they detect changes in resistance, capacitance, or potential due to environmental variations. The working principle involves creating a measurable potential difference or current flow in response to specific stimuli, which is then processed by associated electronics.

常见问题

What is the difference between sensing electrodes and reference electrodes?

Sensing electrodes (working electrodes) actively respond to the measured parameter, while reference electrodes maintain a stable, known potential against which sensing electrode measurements are compared to ensure accuracy.

How often should sensing electrodes be calibrated?

Calibration frequency depends on usage intensity and application criticality. For most industrial applications, electrodes should be calibrated daily to weekly using standard solutions, with more frequent checks in continuous monitoring systems.

Can sensing electrodes be cleaned or maintained?

Yes, proper maintenance includes regular cleaning with appropriate solutions (e.g., mild detergent, specialized electrode cleaners), storage in recommended solutions, and periodic polishing or membrane replacement for certain types. Always follow manufacturer guidelines.
