Signal Conditioners, Process Transmitters, and Converters

Process signal conditioners and process signal transmitters isolate, filter, amplify, and convert sensor signals to 4-20mA current or 0-10V signals for interfacing with controllers and other instrumentation. Select from 2-wire loop-powered 4-20mA transmitters, or 4-wire AC/DC-powered transmitters. Acromag offers 3- and 4-wire models with 4-20mA transmitters or voltage transmitters. DIN-rail and field-mount versions are available. Process transmitter configuration is easy with Windows® software, pushbuttons, switches, or pots for span/zero settings, depending on the series.
