Pressure-to-current converter
This representation identifies conversion of a pressure input to a current-signal output.
IEEE-library pressure-to-current converter form representing a transducer that turns process pressure into a loop current.
In plain English
The pressure/current converter represents a device that turns a measured quantity into a signal that measures pressure and produces a proportional electrical signal, typically a 4-20 mA loop. On control and protection schematics it appears where transformer, compressor or hydraulic pressure is passed to a PLC, relay or indicator.
The block does not tell you the pressure range, whether the output is two-wire loop-powered or four-wire, or whether the measurement is gauge, absolute or differential. Those details govern the wiring and the scaling at the receiving input.
Identify whether the loop is powered by the receiver or the device that turns a measured quantity into a signal. Check scaling of the output current to pressure range. A pressure/current converter gives a continuous signal; a pressure switch gives only a contact change at a set point.
