常见问题

What is the difference between capacitive and conductive sensing probes?

Capacitive probes measure dielectric constant changes and work with both conductive and non-conductive materials, while conductive probes require electrically conductive materials and detect current flow between electrodes.

How do I select the right sensing probe for my application?

Consider material properties (conductivity, viscosity, corrosiveness), process conditions (temperature, pressure), required accuracy, container dimensions, and environmental factors (explosive atmospheres, hygiene requirements).

What maintenance do sensing probes require?

Regular cleaning to prevent buildup, inspection for corrosion or damage, calibration checks every 6-12 months, and replacement of worn components like seals or electrodes.
