High and low level output interface
Non-contact
level sensor for non-metallic container wall without direct contact
with the liquid will not be corrosive acids such as strong acid and
alkali corrosion, free from scale or other debris.
intelligent
level adjustment and liquid level memory function, liquid level status
display, multi-point series connection can be achieved; can support high
and low level output, NPN output, PNP output, MC output, RS485 data
signal output With the 's instructions can be).
detection is accurate and stable, boiling water level can be detected.
pure electronic circuit structure, non-mechanical work, stable performance and life.
High
stability, high sensitivity, just interference ability, free from
external electromagnetic interference, for the frequency interference
and common mode interference have special treatment to be compatible
with all available on the market 5 ~ 24V power adapter.
Strong
compatibility, through a variety of non-metallic containers, such as
plastic, glass, ceramics and other containers, sensing distance up to
12mm or more; liquid, powder, particulate matter can be detected.
open collector output, wide voltage range (5 ~ 24V), suitable for connecting a variety of circuits and product applications.
Intelligent
non-contact level sensor is the use of water sensing capacitor to
detect whether there is liquid in the absence of liquid proximity
sensor, the sensor due to the presence of distributed capacitance, so
there is a certain inductor static capacitance, When the liquid level
rises slowly approaching the sensor, the liquid parasitic capacitance
will be coupled to the static capacitance, the final capacitance of the
inductor becomes larger, the change of the capacitance signal is then
input to the control IC for signal conversion, will change Of the
capacitance
