This
transmitter is the device which detect the liquid levelin the column
an d transmit the signal to thedisplay, which makers the remote
control poss ible.
 |
Principle |
In thetransmitter,
leed sitches and resiste rs are installedat regular intervals as
show n in the Fig.
When the float equipped with magnet appoaches the Ieed switchm the
nearest leed switch will be closed.
With resistance between A and B, voltage change is detected in the
transmitterand the signal is transmitt ed to the autside of ter
converting voltage change into 4-20mA.
Therefore, The float position can be detected.
