Analog Transmitter Manufacturers

Analog transmitter is a field-mounted device that senses a physical parameter such as pressure or temperature and generates a current proportional to the measured variable in the standard range, 4 to 20 mA. Providing the output as a current in a twisted-pair loop has many advantages. The measurement signal is insensitive to noise and is not affected by changes in loop resistance. The transmitters meeting the standard are interchangeable and the power required to energize the transmitter circuits can be derived from a remotely supplied loop voltage.
