Product Description
Working principle
 |
|
| Capacitance type limit switch is a static level sensor,Its sensing parts are:- |
| -Earth Extension (body) |
| -Sensing Rod |
| |
|
 |
|
The capacitance is formed by
the sense rod and earth extension.
When no material is present, the capacitance is analogically a multiple of probe dimension and dielectric constant of air {ε(air)≈1}. |
| |
|
|
 |
|
When material is present,
the capacitance gets multiplied by
dielectric constant of the material.
This variation in capacitance is
then translated into switching
output by the device.
Applications
- Suitable for non-sticky liquids and solids.
