Mescon Technologies, Inc. 20/1(D)

The model 20/1 is a precision, loop powered 2-wire transmitter with galvanic isolation between its input and the current-loop output signal. It provides the necessary circuitry for amplification and linearization of signals from RTD sensor. The input circuit can accept 2 or 3 wire RTD's for either a direct or a differential temperature measurement. An optional LCD indicator is available to indicate actual temperarure in °C or °F. The 20/1 can be easily ranged without requiring special tools or board modifications. The transmitter is a member of Mescon's family of advanced Universal Input transmitters, which may be readily reconfigured to accept other popular inputs such as Thermocouples, DC mV/mA/Volt and Potentiometers. A TEST terminal provides a 40-200 mV output. Applying a DVM to the TEST terminals allows monitoring and verification of the output without interrupting or disconnecting the current loop.
