i need to know how does a pressure transducer converts a pressure into electrical energy

 

Hello,

Here is a page from the EDUCYPEDIA on pressure sensors:
http://educypedia.karadimov.info/electronics/sensorspres.htm

There are pages for other types of sensors also:

Sensors:
Capacitive sensors Inductive sensors Piezo
Displacement sensors Infra red sensors Pressure sensors Temperature sensor types
Encoders and resolvers Magnetoresistive sensors Reed switches Thermocouple
General overview Miscellaneous Temperature: PT100-RTD Tilt Sensors
Hall sensor Optical sensors Temperature sensors Ultrasonic sensors

Greetings,

i need to know how does a pressure transducer converts a pressure into electrical energy

There are several methods, but most use a metal diagram that the pressure pushes against. The deflection of the diagram is picked up be various transducers such as resistive strain gauges, capacitance sensors, etc, which is then converted to a electrical signal that can be measured.
