Vibrating Fork Level Switch Aquafork Swift 700 Series

SALIENT FEATURES :

• Fast and Easy Installation No Calibration.
• No effect of electrical properties of the Service material. High Reliability.
• Suitable for the highly dusty environment.
• Field selectable operation logic. Can be configured either for High or Low level point switching.

* Provides economical solutions, Various model not required. Reduces the Inventory cost.

MEASURING SYSTEM :

• The complete system, AQUAFORK -7000... series, consists of :-
• The sensing probe of Vibrating Fork and The Electronic Switching unit

FUNCTION:

The electronically stimulated fork vibrates at its mechanically resonance frequency of about 400 Hz when the fork is free of the service material. The resonance is caused by the piezoelectric crystals. One of the piezo crystals produces a small voltage which is transmitted to the switching amplifier. If the fork is covered by the bulk material, a damping effect is produced and the piezo crystal does not produce the voltage and the amplifier will switch and a corresponding signal output is actuated. The vibration of the fork has self-cleaning properties.

The light deposit on the container wall does not affect the operation of the AQUAFORK

APPLICATIONS :

• Most liquids with max 10000 mm2/s viscosity. Corressive, thick, turbulent, flowing liguids.
