The Micron Meters 4-20 mA and RS232/RS485 output, process signal input transmitter provides zero and span adjustment for use with a wide range of industrial transducers. Six DC voltage and four DC current input ranges are jumper selectable. The two most sensitive voltage ranges, 200.00 mV and 2.0000V, provide a high input impedance of 1 GΩ to minimize the load on the voltage signal.
The transmitter can be set to a ratio mode (or potentiometer follower mode) by making selections at the connector and in software. In this mode, the transmitter output tracks a ratio of the applied excitation voltage and is unaffected by changes in the excitation voltage. This capability is used for resistive bridge sensors and voltage dividers, such as potentiometers which track wiper position. Ratiometric measurements provide an exceptional accuracy of 0.01% of reading ± 2 counts.
Fast read rates at up to 50 or 60 conversions per second while integrating the signal over a full power line cycle are ideal for peak or valley capture and for real-time computer interface and control. Digital signal filtering modes are selectable for stable readings in electrically noisy environments. The internal digital readings and analog output can be individually selected to be either unfiltered or filtered.
Standard features of Micron LT transmitters include:
Easy Transmitter programming is via the Instrument Setup Software, which runs on a PC under MS Windows. This software can be downloaded from this website at no charge. The required transmitter-to-PC interface cable is available. (P/N CBL04).
