Honeywell transmitters offer changed the name suggests, the transmitter contains a "change" and "send" means. The so-called "variable" refers to the various physical quantities from the sensors, converted into an electrical signal. For example: the use of a thermocouple, the temperature change of the potential; the use of a current transformer, the large current into a small current. Since the most easy to handle electrical signals, so the modern transmitters, both the physical signals, into an electrical signal. Therefore, selection of Honeywell transmitters, transmitters we say, often become "electric." The so-called "free" Honeywell transmitters, refers to a variety of signals has become, in order to facilitate the other instrument or control device to receive and transmit, and again by the electronic circuit Honeywell transmitter technology, sensors to electrical signals, unified (eg 4-20MA). The method is realized by a plurality of operational amplifiers. This "change" + "send" on the formation of the modern most common transmitter.
