- Marketing Description - The RKI M2Aâ„¢ is a state-of-the-art transmitter that can operate as an independent, stand alone monitor or as part of an integrated system. The M2Aâ„¢ connects with an analog or digital signal to virtually any controller, PLC, or DCS. Setup procedures are simplified with user friendly push buttons and OLED menus. It utilizes a magnetic wand technique for performing non-intrusive calibration. The M2Aâ„¢ provides an automatic zero drift correction feature, which results in more stable readings and reduces the need for adjustments due to sensor aging. The housing of the M2Aâ„¢ does not need to be opened for zeroing or calibration, making it unnecessary to declassify the area for routine maintenance. It is designed so that a complete field calibration can be performed by one person. Sensor construction is rated Class I, Div. 1 Groups B, C, D for flammables, CO, H2S, O2, and CO2, and Class I, Div. 2 for all other toxics. The transmitter provides a 4 to 20 mA output in addition to a Modbus digital output. It also has two levels of alarms with relays, plus a fail alarm with relay. A digital display of the gas concentration, as well as alarm and status lights, can be viewed through the front window. The toxic sensors are electrochemical type plug-in sensors, which provide high specificity, fast response, and long life. The plug-in design allows quick replacement in the field with no tools required. Toxic sensors are designed for use in Class I, Div. 2 hazardous locations. Sensors available for NH3, SO2, PH3, AsH3, and HCN. The M2Aâ„¢ represents the latest leading edge technology in sensor/transmitters today.
