The I to P and P to I trainer, is an extension of the I to P trainer. This is a combination of two transducers in one unit. The I to P takes 4 to 20 mA as input and provides, output pressure in the range of 3 to 15 PSI. Whereas P to I transducer takes 3 to 15 PSI as input and generates 4 – to 20 mA as output current. This trainer consists of one each of the above transducers. The output of I to P transducer is given as Input of P to I transducer. A pressure gauge indicates the output of I to P and Input of P to I transducers. Two separate current meters monitor the currents of both transducers.
A filter line regulation unit provides moisture free air to the trainer. Dedicated built-in DC power supply and interface electronics are provided with the instrument. In manual mode, a variable potentiometer provides current to the I to P transducer. Automatic mode is possible, when connected to Computer Applications Trainer, Model DAS-1. The user must provide 5Kg/Cm2 compressed air power from a compressor.
