The M2 Stand Alone Transmitter is operational with or without a controller and is available in two forms: explosion proof and non-explosion proof. The unit has a backlit screen for a direct digital readout, and a user friendly setup with push buttons and easy to read LCD menus. The advanced technology transmitter can function as an independent standalone system or as part of an integrated detection and transmission system. Using state of the art technology, the transmitter uses a magnetic want technique for performing non-intrusive calibration. For optimal stability and accurate readings, the unit provides an automatic zero drift correction feature. This also reduces the need for adjustments due to sensor aging.

The M2 Stand Alone Transmitter is available for LEL, H2S, CO, PPM, HC, CO2, CI2, NH3, SO2, HCN, and more. The unit also features an infrared sensor for CO2 and combustible gases. With 2 fully programmable alarms and a fail relay, the visual color coded LED alarms are reliable and customizable to meet specific needs.

Advanced sensor technology

The state of the art sensors are long lasting with a lifespan typically over two years. Sensor construction is rated Class I, Division 1 groups B, C, and D for flammables, CO, H2S, O2, and CO2. The sensors are rated Class I, Division 2 for all other toxic gases. Depending on the gas, the sensors will operate through a catalytic, galvanic cell, electrochemical, or infrared design. The plug in nature of the sensors allows for a quick and tool free onsite replacement.

Specifications

Each transmitter features 2 to 3 years of life with normal service. The explosion proof LEL H2 specific transmitter has 3 to 5 years with normal service, and the explosion proof carbon dioxide, methane, and hydrocarbons feature over 5 years of life with normal service. The explosion proof transmitters are also water repellant. Each device is approximately 8.5 H x 5.2 W x 4.5 D and features an alphanumeric display with a backlight. The screen displays 8 characters per line with 2 lines for gas concentration readouts.

Optional Accessories

The M2 Stand Alone Transmitter has a variety of optional accessories available including calibration adaptors, flow through adaptors, remote horns and lights, calibration kits, battery backups, splash guards, air aspirator adaptors or panels, and dataloggers. The transmitters are directly compatible with Beacon 110, 200, 410, and 800 controllers.

35-3010RK-02 LEL (Internal Amp)/O2 (Internal Amp)/H2S (4-20mA) Sample Draw Assembly in NEMA 4X Enclosure by RKI Instruments

The 35-3010RK series is a compact sample draw detector assembly with a built-in pump that accepts a 24VDC input. This unit features a NEMA 4X enclosure making it dust, water and corrosion resistant. It also features a flowmeter with adjustable flow and a low flow alarm which warns of any obstructions or restrictions in the flow system. Combustibles, oxygen, hydrogen sulfide and carbon monoxide versions are available in many different combinations. Combustibles and oxygen versions can be suplied with or without a 4-20 mA transmitter. The 35-3010RK series can also be configured with RKI's super toxic sensors offering a wide range of detectable toxic gases.

The 35-3010RK is capable of single person calibrations and can be installed up to 500 ft. from a controller, and can interface to any RKI or third party control system (utilizing a 4-20 mA feedback signal).

With the introduction of their high performing, low cost S2 Sensor Transmitter, RKI is fulfilling that commitment.

S2 Sensor/Transmitter

The RKI S2 Sensors and Transmitters use state of the art sensor technology to detect common gas hazards. Their efficient design and cost effectiveness make them an industry choice for atmospheric monitoring. The sensor transmitters can be used in both indoor and outdoor conditions and are designed to interface with RKI controllers or PLC/DCS systems.

The sensors are available in explosion proof casing for monitoring LEL, H2 specific, oxygen, H2S, CO2, and carbon monoxide. These sensors also have flame arrestors and are approved for use in hazardous environments. The oxygen, H2S, CO, and CO2 sensors are available in non-explosion proof models. The sensors provide highly specific and quick detection and are long lasting. The sensors can be quickly replaced while on the field and do not require any tools.

Explosion proof S2 Sensor/Transmitter

The explosion proof sensors use a variety of detection mechanisms including catalytic for LEL and LEL- H2 specific; metal oxide semiconductor for hydrogen; galvanic cell technology for oxygen; electrochemical for hydrogen sulfide and carbon monoxide; and infrared for carbon dioxide, methane, and hydrocarbons. A hydrogen specific sensor transmitter is not available. Each of these detection methods come with their own measuring range specifications and response times varying from 20 seconds to 45 seconds. These sensors are stainless steel and are housed in a cast aluminum explosion proof J-Box (a stainless steel J-Box is also available).

Non-explosion proof S2 Sensor/Transmitter

The non-explosion proof sensors use galvanic cells for oxygen detection; electrochemical technology for hydrogen sulfide, carbon monoxide, and other toxics; and infrared technology for carbon dioxide detection. The response times vary between 20 seconds and 60 seconds depending on the targeted gas, and the measuring ranges vary as well. These sensors are plastic or aluminum and housed in an explosion proof J-Box.

Accessories

The S2 Sensor/Transmitter has numerous accessories available to meet the individual workplace's needs. Such accessories include calibration adaptors, flow through adaptors, remote horns and lights, calibration kits, battery backups, splash guards, air aspirator adaptors or panels, and data loggers.

Each sensor comes standard with a one year warranty for materials and workmanship.
