- Insensitive to contamination
Relay unit with sequential logic circuit (RE9000) ignores affection from scum, suspended solids or other contamination. - Extremely rugged
Having no moving parts, the sensor offers long service life. - Easy-to-use relay unit
Mounting the sensor is easy with a cleaner and a mounting bracket. - Suitable for a wide range of applications
DIP switch on relay unit allows measurement of various liquids.
(Sensitivity: 1k? to 80k?)
Principle of Operation
Sensor uses conductivity between the electrode and the ground to detect a level. For FRP or other plastic tanks, an earth electrode is required.
The sensor has a pair of electrodes, and applies alternating current to them. When the liquid covers the electrodes, it forms a part of an electric circuit, causing current to flow. The sensor measures electric resistance of the liquid, and compares the measured value with a preset value to determine liquid presence. When liquid presence is detected, the sensor sends a signal to an amplifier to open or close relay contacts of relay units.
