Mescon Technologies, Inc. 20/3(D)

The model 20/3 is a precision, loop powered 2-wire transmitter with galvanic isolation between its input and the current-loop output signal. The 20/3 provides the necessary circuitry for amplification and processing of DC mV/mA/Volt signals from various sensors and signal sources.Model 20/3L also provides input linearization to correct for non-linearity of many input sensors. An optional LCD indicator is available to indicate the output in Engineering Units.The 20/3 can be easily ranged without requiring special tools or board modifications. The transmitter is a member of Mescon's family of advanced Universal Input 2-wire transmitters and signal conditioners. As such it can be readily reconfigured to accept other popular input types such as RTD, Thermocouples and Potentiometers. A TEST terminal provides a 40-200 mV signal proportional to the 4-20mA output. Applying a DVM to the TEST terminals allows monitoring and verification of the output without interrupting or disconnecting the current loop.
