In a further preferred embodiment, tuning-fork type level gauging switch is using the probe of multiple different length sizes.
Traditional floating ball type liquid level measurement switch is changed into tuning-fork type level gauging switch and coordinate related auxiliary equipment
Realize level gauging function.The detection process of Fork LIquid Level Switch is completed by electronic circuit, no-movable part, so once installation
Put into operation and just do not need to safeguard；By the high frequency pumping of piezoquartz, Fork LIquid Level Switch has excellent anti-noise jamming ability；
Later stage also accommodates, according to the probe of different length, the demand that various density fluid detect；Due to being opened using tuning fork level gauging
Close, thus without situations such as mechanical wear and liquid corrosion of occurring similar to float type level switch occurs, thus providing
Accurately, reliably it is collected data；The signal processing module that liquid level measuring system is mated has fast operation, reliable results
Property high the features such as, for follow-up equipment to liquid level signal call offer basis；The signal output module of liquid level measuring system has
Extended capability is strong, the advantages of transmission result is accurate, different types of auxiliary equipment in collocation, and can farthest realize liquid level and believe
Number call, export.Modular design, be easy to directly perceived, be accurately read and process signal parameter, simultaneously for the dimension of equipment
Shield, maintenance provide facility.
Finally it should be noted that:The above example only technical scheme in order to this case to be described is not intended to limit；Although
With reference to preferred embodiment, this case is described in detail, those of ordinary skill in the art should be understood：Still permissible
The specific embodiment of this case is modified or equivalent is carried out to some technical characteristics；Without deviating from this case technical side
The spirit of case, it all should be covered in the middle of the technical scheme scope that this case is claimed.
