DIRECT ANSWER
What is the practical starting point?
Select a capacitance level transmitter by medium dielectric behavior, conductivity, probe construction, installation, temperature, pressure and expected coating. The measuring range alone is not sufficient.
SELECTION FACTORS
Data to confirm before model selection
Use this list to prepare a traceable quotation request.
- 01Identify whether the application is continuous level or point detection.
- 02Record dielectric changes across recipes or concentration.
- 03Choose probe material and insulation for the medium.
- 04Review buildup, grounding, nozzle and vessel geometry.
- 05Confirm range, temperature, pressure, output and hazardous-area needs.
TECHNOLOGY COMPARISON
Compare the decision factors
| Factor | Why it matters |
|---|---|
| Dielectric constant | It determines the capacitance change available for measurement |
| Probe and insulation | They define chemical, mechanical and electrical compatibility |
| Buildup | Coating can add capacitance and shift the measurement |
| Installation | Grounding, nozzle and nearby metal affect the sensing field |
FAQ
Questions engineers ask first
Last reviewed:
Can capacitance measure non-conductive liquids?
It can be suitable when the dielectric behavior, probe arrangement and calibration are appropriate; the exact model must be checked.
What causes capacitance level drift?
Changing dielectric properties, coating, moisture, grounding and installation changes are common investigation points.
