Conductivity Level Sensor ▶ Check out the full blog post over at http://realpars.com/level-sensor/ A conductivity or resistance sensor uses a probe to read conductivity. When a liquid covers the probe its electrodes form a part on an electric circuit, causing current to flow which signals a high or low level. Watch the video and answer the question. Is the voltage applied to a Conductivity Level Sensor Probe AC or DC? #Conductivity #LevelSensor #LevelMeasurement #IndustrialAutomation #Automation
