Within the block / circuit diagram
illustrated below, the sensing element senses the pressure of
the monitored system and converts the pressure to a
mechanical signal. The sensing element supplies the
mechanical signal to a transducer, as discussed above. The
transducer converts the mechanical signal to an electrical
signal that is proportional to system pressure. If the
mechanical signal from the sensing element is used directly,
a transducer is not required and therefore not used. The
detector circuitry will amplify and/or transmit this signal
to the pressure indicator. The electrical signal generated by
the detection circuitry is proportional to system pressure.
The exact operation of detector circuitry depends upon the
type of transducer used. The pressure indicator provides
remote indication of the system pressure being measured.
