A pressure transducer, often called a pressure transmitter, is a transducer that converts pressure into an analog electrical signal. The conversion of pressure into an electrical signal is achieved by the physical deformation of strain gauges which are bonded into the diaphragm of the pressure transducer and wired into a Wheatstone bridge configuration.

Following are the various types of pressure transducers –

1. Capacitive Pressure Transducer

   • Ranges of 0-2 psi through 0-10,000 psi; 5 lb through 1,000,000 lb

2. Load Cell or Pressure Cell

• Load range is from 5lb through 500,000 lb (Honeywell)

1. Piezo Electric Transducer

   • Range is0-450 psi

2. LVDT

   • Voltage range from 1V to 24V RMS/50 Hz to 20 kHz

3. Ceramic Thick Film Sensor

• Range from 0-1000 psi

1. Thin Film Sensor

• Range from 0-350 psi
