Material level sensorTechnical parameters (capacitive)Material level sensor）

1. Medium temperature: -40~800 ℃

2. Medium pressure: ≤ 3MPa

3. Working environment: Temperature -25-45 ℃

4. Work pressure: Normal pressure

5. Power supply voltage: AC 220V or DC24V.

6. Connection size: 1R or 1.5R pipe thread.

7. Output mode: Relay contacts, a set of normally open and normally closed contacts.

8. Work sensitivity: 3-6p (i.e. the increase in environmental capacitance caused by the buried electrode when it is not partially buried by the material)

When ≥ 3-6p, the relay is engaged.

9. Return difference: 1-3p (i.e. when the material (liquid) level rises and the relay is closed, when the material (liquid) level drops,

The relay does not immediately release and needs to be lowered to a distance of about 1-3p when the environmental capacitance decreases from the suction point,

The relay is only released, effectively avoiding frequent suction and discharge of the relay at critical points.

10 action delay: 2-3 seconds
