Vibrating Level Switch

Advantages

1. Can detect objects with low specific gravity (light weight). It is suitable for objects to be measured that are idled by the paddle switch.
2. Can detect objects with low relative permittivity. It is suitable for objects with a low dielectric constant that are difficult to adjust with a capacitive level switch.

Features

• Detects ultralight fine powder!
• Not affected by electrical characteristics
• Five functions that emphasize on-site usability

Operating principle

The detection probe of the vibrating level switch has a dual structure of an inner probe and an outer probe. When the inner probe is slightly vibrated at a certain frequency by a piezoelectric element, the outer probe resonates. Resonance is greatly reduced by burying the outer probe in the stored material, and the change is captured and detected.

How to use?

1. Determine the mounting position
   
   Mounts to ceiling or tank sidewall. Avoid installing near sources of intense vibration such as knockers, which may cause malfunction or false detection.
2. Mounting:
   
   Avoid direct contact with the electrode while it is being charged, as this may cause damage. It is effective to attach a protection plate. Also, when installing on the lower side wall, tilting the probe by 20° or more can reduce the load on the probe.
3. Wiring:
   
   The power supply is a free power supply and supports AC/DC22~264V 50/60Hz. The output signal is SPDT and the contact capacity is AC250V, 5A/DC30V, 5A.
4. Adjustment:
   Sensitivity adjustment is only sensitivity adjustment by volume. Next, by setting the detection operation selector switch, it is possible to set contact output operation for upper and lower limits and lamp display.
