Capacitive Liquid Level Sensing (1): Sensor Basics

First part, covering capacitance and general sensors design … ↓↓↓ Complete description, time index and links below ↓↓↓ Capacitive liquid level sensors are neat: They have no moving parts, there is no current flowing through the liquid you measure, and the capacitive sensors themselves are fairly easy to build. But of course they come with their own challenges. We first have a look at the theory of capacitance, in order to understand what influences the capacity of a capacitive liquid level sensor. Then we proceed to do some experiments with different basic capacitive liquid level sensor designs. 00:00 Intro – capacitive liquid level sensing 00:11 Capacitors – what influences the capacity 02:41 Capacitance – the theory without math 14:51 Demo – of parallel plate capacitor 16:31 Experiment 1 – plates close together 19:49 Experiment 2 – plates with cavity in between 22:49 Experiment 3 – plates at distance without cavity 24:39 Experiment 4 – plates outside liquid container 29:28 Experiment 5 – metal container with plate inside 31:50 Wrap-up – next is measuring the capacity, bye Tutorials    • Tutorials   #liquid #sensor #capacitance #capacity #capacitor #tutorials #tutorial #how-to #robertssmorgasbord
