DBW two-wire electric temperature transmitter is a transmitter unit of DDZ-Ⅲ electric unit combination meter which can be form automatically adjust loop, or indicated loop with regulator, actuator indicator, recorder, etc. It is on-site installation.

Due to affect of lower limit of output signal, two-wire transmitter generally does not have a linear correction circuit. So the output of the transmitter only has direct ratio with millivolt (TC), △ R (thermal resistance)

In order to do accurate temperature indication, the temperature scale of secondary instrument (regulation instrument, indicator, recorder, etc.)  which completed with this series products is consistent with millivolt (or △ R) of temperature components.
