FAQ

Stainless steel capacitive level transmitters are suitable for a variety of liquids and some solid particulate media, including water, oils, chemical solutions, corrosive liquids, slurries, powders, and granular materials. They are particularly ideal for media with stable dielectric constants. For media with significant foaming, strong adhesion, or large variations in dielectric constant, specific adjustments are needed during selection and parameter setting.

Yes, capacitive level transmitters usually require calibration during initial installation or when the medium changes. Common calibration methods include empty tank calibration and full-scale calibration. By setting the zero point and span under no-medium and full-scale liquid level conditions, the output signal is ensured to accurately correspond to the actual liquid level. Some models support on-site button calibration or remote parameter setting, which is relatively simple to operate.

Media adhesion or scaling on the probe surface can indeed affect capacitive measurement, especially after long-term operation. To reduce such effects, a probe with an anti-adhesion coating can be selected, or measurement accuracy can be maintained through parameter compensation and regular cleaning. In highly adhesive conditions, it is recommended to conduct an on-site assessment in advance and select a suitable probe structure.
