New multi-controller introduced The new AM3 multi-controller from gas technology specialist Witt is presented as a compact all-rounder, displaying values, monitoring processes, logging data and controlling systems. The versatile instrument processes 4-20 mA signals from a wide variety of signal sources, eg pressure transmitters, or temperature or level sensors, and can simultaneously monitor various systems. The alarms can be acknowledged directly via the touch display. All received important values, such as alarms, can be stored via the integrated data logger. In addition to the alarm function, the AM3 can be used as a device for monitoring external control systems.

This practical helper for process control has an easy-to-read TFT display, which activates automatically when approached. Device parameters such as alarm limit values can be easily set using capacitive keys. The graphic menu navigation is clear and intuitive. Depending on requirements, different international units such as bar, psi or kPa can be selected. Integrated into Witt gas mixers, the controller is used to monitor the inlet pressures and the vessel pressure, and

The AM3 Multi-Controller can be used as a stand-alone unit with a separate housing, but is also suitable for front panel mounting due to its small size. The analogue inputs and outputs enable communication with external systems. The AM3 can be used as a display unit for virtually any application with electrical signals in the 4 to 20 mA range. The small console also has built-in alarm functions and can manage up to eight alarms.

Witt’s compact AM3 multi-controller

replaces the previous alarm module. Because of unchanged installation dimensions, the module can easily be retrofitted onto Witt gas mixers that previously used the Witt alarm module. Witt-Gasetechnik GmbH & Co KG – Germany www.wittgas.com
