Tronic Line Introduction Linearity Accuracy Performance Applications Tronic Line Products Introduction All WIKA Tronic pressure transmitters and transducers convert an applied pressure into an electrical signal. Because of its popularity, WIKA stocks a large inventory of 4-20 mA output transmitters in many different models. By convention a pressure transmitter provides a mA output while a pressure transducer provides a voltage output.
Many users refer to transmitters and transducers interchangeably.
This can create some confusion, but it may be helpful to note that general purpose pressure sensors are most commonly referred to as pressure transducers . What makes these devices useful is that the output, regardless of type, is linear. This means that the output is directly proportional to the applied pressure. WIKA transmitters are fixed range devices, and are described in part by pressure range and output type. Because the transmitter output is linear, it will directly relate to the applied pressure.
