What is a capacitive liquid level sensor and how does it work?

A capacitive liquid level sensor measures level by detecting changes in dielectric constant between the probe and surrounding medium. As the liquid level changes, capacitance varies, which is converted into a stable electrical signal (typically 4–20mA).

Can capacitive level sensors measure oil and water simultaneously?

Yes. Advanced designs with PTFE coating can distinguish between oil and water due to their different dielectric constants, making them ideal for mixed media applications.

What are the advantages of capacitive level sensors over ultrasonic or radar sensors?

Capacitive sensors provide:

أداء أفضل في الخزانات الصغيرة
Higher sensitivity in interface detection
Lower cost and simpler installation
Reliable operation without signal reflection issues

Are capacitive level sensors suitable for high-temperature environments?

Yes. High-quality models can operate up to 150°C, especially those with thermal management designs that protect internal electronics from overheating.
