The RKI M2™ is a state-of-the-art transmitter that can operate as an independent, stand-alone system or as part of a system connected with an analog or digital signal to virtually any controller, PLC, or DCS. The M2 series detects LEL combustibles, oxygen, hydrogen sulfide, or carbon monoxide. It utilizes a magnetic wand technique for performing non-intrusive calibration. The M2 provides an automatic zero drift correction feature, which results in more stable readings and reduces the need for adjustments due to sensor aging.
The M2 housing does not need to be opened for zeroing or calibration, making it unnecessary to declassify the area for routine maintenance. Internal push-buttons can also be used if the housing is opened. It is designed so that a complete field calibration can be performed by one person. The stainless steel flame arrestor that covers the sensor (LEL, H2S, CO, or XP Oxygen) is water repellent with a special patented water resistant coating.
The M2 provides a 4-20 mA output in addition to a Modbus digital output. It also has two levels of alarm with relays, plus a fail alarm with a relay. A digital display of the gas concentration, as well as alarm and status lights can be viewed through the front window.
The M2 represents the latest leading edge technology in sensor / transmitters today. |
