| description | Transducers are predominantly used as sensors, because with a few exceptions,
their efficiency of conversion is very low and to achieve a higher efficiency of
conversion, transducers need to use the electrical signals to the amplifier. The
piezoelectric device (pressure sensing) is also a useful transducer (can be used in either
direction). Transducer use of piezoelectric crystals is mainly confined to the conversion
between pressure waves in a liquid or gas and electrical AC signals. The conversion of
energy from an electrical form into stress can be achieved by the magnetically cored
solenoids. Pressure Transducer operates to convert the physical variable pressure into
an electrical output signal that is proportional to the pressure measurement. The output
supply is in form of current or voltage signals. Standard signals allow combining
transducers, controllers, computers or stored program controllers (SPC) of different
manufacturers without incurring any problem. The standardization simplifies both
works as the manufacturers and also as the designer or any company operating
instruments and plants. Capacitive Pressure Transducer operates as a pressure
sensing device which senses the changes of capacitance according to the changes of
pressure applied to the transducer. The measurement of these changes (output) is
defined in form of voltage signal using a special measurement circuit is build out of
operational amplifiers, resistors, capacitors and switch. The measurement results and
conclusion of the project conducted on the capacitive pressure transducer is presented
in the last part of this report together with design of the pressure transducer and the
measurement circuit. |
