Simple, Low-Cost 4 mA to 20 mA Pressure Transmitter Technical Note INTRODUCTION The two wire 4 mA to 20 mA transmission loop is one of the most popular output signals for pressure sensing devices in industrial applications. The use of current as a transmission signal provides a low impedance transmission path which is less susceptible to induced
