The principle of L2000 level switch

The working principle is based on the radio frequency (RF) capacitor technology. A radio frequency applied to the probe, through continuous analysis, determine the impact caused by the surrounding environment.Because all materials have a dielectric constant, and conductivity are different from the air, when the probe is in contact with the materials as the total impedance of small capacitance offset reflects the change.

The characteristics of L2000 level switch

Versatility: can be applied to a variety of conductive and non-conductive dielectric measurement, such as liquid,viscous, particles, powder, fly ash.

Anti adhesion: using patented anti adhesion circuit, can eliminate the false signal generated due to materialadhesion.

Probe: no detachable cable connection between the controller and the probe, at any time can be removedwithout affecting the controller replacement repair, import materials.

High temperature: suitable for -184 to 280 DEG C working environment, can provide other ceramic probesuitable for higher temperature.

Output form: double pole double throw relay signal output, and a status display output state, and have 0 to 30 seconds of delay function.
