Removable Probe RF Admittance Switch Anti Adhesion
Working Principle of RF Admittance Switch
The tuning fork type liquid level limit switch is not affected by the dielectric constant, turbulence, agitation, bubbles, vibration and other factors, and has no moving parts.When the tuning fork is immersed in liquid or solid, the vibration frequency changes. This frequency change is detected by the electronic circuit as a switching value. Therefore, it does not need maintenance and adjustment. It is an ideal choice for liquid level switches under complex working conditions. The latest intelligent chip can be used as an oil-water interface switch.The tuning fork is excited by the piezoelectric crystal to generate vibration.
Design feature of RF Admittance Switch
◎ Strong versatility: it can be applied to the measurement of various conductive and non-conductive media, such as liquid, viscous substance, particle, powder and fly ash
◎anti adhesion: the patented anti adhesion circuit can eliminate false signals caused by material adhesion.
◎ detachable probe: there is no cable connection between the controller and the probe, and the controller can be removed, replaced and repaired at any time, without affecting the incoming and outgoing materials.
◎ High and low temperature resistance: suitable for the working environment of - 184 ℃ to 280 ℃, and ceramic probes suitable for higher temperatures can be provided.
◎ output form: double pole double throw relay signal output, and a status lamp displays the output status, with a delay function of 0 to 30 seconds
◎ intelligent diagnosis: after turn on, the instrument circuit automatically detects whether the working state is normal.
