DESCRIPTION:
The present set-up is designed to study the working principle and calibration procedure of P/I converter and I/P converter. Air pressure is given to both by compressed air supply. Output generated by both converters is observed and measured. P/I converter accepts the pressure input 0-1 bar and gives output 4- 20 mA DC accordingly, which can be measured using Digital Current Meter and in case of I/P converter, the current input of 4-20 mA DC is given to I/P Converter by Digital Current Source and output response in 3-15 PSIG is observed and measured by Bourdon type Pressure Gauge. Th set-up is self-contained with Air pressure regulator, pressure gauges and necessary piping. All component and accessories are properly mounted on the rigid MS structure and fitted on a base plate to form a table top set-up.
EXPERIMENTATION:
To study of working principle and calibration procedure of I/P converter.
