RKI Instruments M2 Series
Fixed Gas Detection System
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 housing of the M2 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. The stainless steel flame arrestor housing that covers the sensor (LEL, H2S, CO, or XP Oxygen) is water repellent with a special patented water resistant coating.
The transmitter 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.
Features:
» Operates independent of a controller
» Direct digital readout on backlit LCD
» Available for LEL, H2S, CO, and O2
» 4-20 mA & digital Modbus outputs standard
» Non-intrusive calibration via magnetic wand
» 2 fully programmable alarm relays & fail relay
» H2 specific LEL version available
» Infrared combustible version available
» Patented water repellent sensor coating
» User friendly setup push buttons & LCD
