vibration tuning fork level switch
GENERAL
The vibrating fork type level switch working principle is simple and effective. This makes vibrating
fork type level switches reliable, cost effective and very popular for use in detecting the presence or
absence of liquids and bulk solid materials. The vibrating fork type level switch working principleis ba
sed upon detecting the change in harmonic vibration frequency of the sensing element as a result of
the presence of the target media.
FEATURES
Power consumption: ≤ 2W
Vibration frequency:300±50HZ
Switch signal operating time: 1-60s
