Pressure Transmitter & Transducer

Both transducers and transmitters convert energy from one form to another and give an output signal. The signal is directed to any device that interprets it and uses it to display record or alter the pressure in a system.

So how do you decide whether it is best to use a transducer or transmitter for you application? Transducers and transmitters are virtually the same thing, the main difference being the kind of electrical signal each sends. A transducer sends a signal in volts (V) or millivolt (mV) and a transmitter sends a signal in milliamps (mA). If the electrical connections in your process are short, such as in laboratory or inside an electronics enclosure, a pressure transducer is more desirable as they tend to be smaller and there are very few active electronic components that can be upset by electromagnetic interference.
