Signal Converters and Process Transmitters
Process signal transmitters and signal converters 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, Agility® mobile app pushbuttons, switches, or pots for span/zero settings, depending on the series.Showing 49–61 of 61 results

Signal Conditioners, Transmitters and Converters Continued

Acromag high-performance signal conditioner products include process transmitters, 4-20mA signal isolators, limit alarms, signal splitters, and math computation modules. These products isolate, amplify, filter, condition, and convert measured signals from sensors and other instruments. The enhanced signal is ready for interfacing to your PLC, DCS, display, recorder, or other process control instrumentation.
Temperature transmitters convert thermocouple, RTD, and low-level temperature sensor signals to 4-20mA, 0-10V, or other DC voltage/current outputs. Acromag offers temperature transmitters in head-mount and DIN-rail form factors. Some temperature transmitters have software-configured universal input to convert a broad range of temperature sensor and other signals with a single unit.
