A transmitter (sometimes abbreviated XMTR) is an electronic device which with the aid of an antenna propagates an electromagnetic signal such as radio, television, or other telecommunications.

A transmitter (sometimes abbreviated XMTR) is an electronic device which with the aid of an antenna propagates an electromagnetic signal such as radio, television, or other telecommunications.

In industrial process control a "transmitter" is any device which converts measurements from a sensor into a signal to be received, usually sent via wires, by some display or control device located a distance away. Typically in process control applications the "transmitter" will output a 4-20 mA current loop or digital [[protocol]] to represent a measured variable within a range. For example, a pressure transmitter might use 4 ma as a representation for 50 psig of pressure and 20 ma as 1000 psig of pressure and any value in between proportionately ranged between 50 and 1000 psig. Older [[technology]] transmitters used pneumatic pressure typically ranged between 3 to 15 psig (20 to 100 kPa) to represent a process variable. [http://en.wikipedia.org/wiki/Transmitter]

In the [[context]] of [[The Teaching Mission]], it is understood that '''transmitters''' (or [[TR]]'s) are those [[human]] personalities offering the use of their [[mind]] and [[voice]] to give expression to celestial [[teachers]] who remain unseen. For a list of these TR's see: [http://nordan.daynal.org/wiki/index.php?title=Category:TR]
