Product Introduce
AFTL tuning fork vibration level switch is caused to vibrate by the resonance
of the piezoelectric crystal. When effected by the material damping, the amplitude
suddenly reduces, then the frequency and phase change significantly. These
changes will be detected by the internal electronic circuit, and be transformed into
a switching signal output. The product can monitor, control and alar m the high and
low bit of tanks. Also it is suitable for a variety of liquid, powder , granular solid. It is
practical£¬ simple£¬ reliable£¬ adaptable and maintenance-free. The tuning for k
and output have working condition and diode indicator, which can be adjusted as
habit. Also it has two power supply input modes(220V AC and 24V DC) and many
power supply output modes(DC output type, DC voltage output type, relay contact
output type). All types have high and low alarm sets, which can be done sensitivity
setting according to the situation.
