About This Product
■Features
An electrode level switch is a level sensor for detecting the level of liquid. When the electrode comes into contact with liquid, the circuit is closed and the switch operates. Please use it for control, alarm, etc.
■Advantages
・Achieves multi-contact detection at low cost.
・Since there are no moving parts, it can be used stably for a long period of time.
-Customers can freely change the detection position by cutting the electrode part.
- Compatible with various liquids by changing the material of the electrode part.
■Up to 6 points detection with 1 unit
One level switch can output up to 6 points of contact, making it possible to construct level measurements at low cost.
■Can be used with various liquids
By changing the material of the electrode part, it can be used with various liquids.
■Structure that is resistant to steam inside the tank
By covering the area other than the electrode at the tip, there will be no malfunction even if floating objects come into contact with it.
■Operating principle
Electrode level switches are used in combination with relay units. The relay unit supplies a weak alternating current, so if the surface of the conductive liquid is not in contact with the electrode rod, no current will flow to the electrode, and when the electrode rod touches the liquid surface, the current will not flow. It flows. When current flows, the relay contacts open and close and notify you of detection or non-detection.
■Installation
Install the electrode type level switch vertically.
■Electrode connection
1: Pass through the separator (if the electrode rod is 1m or longer), lock nut, and spring washer in this order.
2: Loosen the set screw on the connector, screw the electrode rod into the center of the connector, and tighten the set screw again to secure it in place.
3: After fixing, tighten the lock nut to prevent it from falling off.
■Ensuring continuity
When cutting the electrode rod to match the control level, remove 10 mm of the coating from the tip to ensure continuity. (Excluding earth electrode)
■Wire connection
Please use electric wires of approximately 1.25sq. Use M3 screws with a pitch of 7 mm between terminals and crimp terminals. *Please prepare a product with current protection separately for the relay unit. (Recommended product: OMRON 61F series)
