Tuning fork level switch

 

Product Description:

 

Tuning fork  level switch can monitor, control and alarm 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 fork and output have working condition and diode indicator. 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.
