61-0140RK Sensor, LEL Combustible (Catalytic), Direct Connection (No Transmitter, No J-Box), UL Version by RKI Instruments

When working on potentially hazardous jobsites, safety managers should look for workplace safety solutions that are dependable and steadfast. When lives are on the line, a workplace cannot afford subpar safety products. That is why, at RKI Instruments, workplace safety is a top priority. Their Research and Development team work daily to integrate the latest technology with the best industry practices. With a reputation for excellent products, RKI Instruments introduces the latest in direct connect sensor technology. Designed for use in Class 1, Division 2 hazardous environments, the Direct Connect Sensors are designed specifically for RKI Beacon 110, 200, and 410 controllers.

Direct Connect Sensors

The RKI Direct Connect Sensors series gas sensors are state of the art gas detection sensors available for LEL, H2 Specific LEL, LEL IR, Oxygen, H2S, CO, CO2, and a variety of toxic gases. To use the Direct Connect Sensors, they can be used for remote detection by mounting them onto explosion proof junction boxes, or they can mount directly onto controllers and be used as a completely standalone system. Their unique plugin design allows for a quick and easy tool free installation on jobsites.

Detection solutions for a variety of hazardous environments

The Direct Connect Sensors are designed to be use in both indoor and outdoor settings. Additionally, some of the sensors are available in explosion proof models. The explosion proof models utilize a patented coating which serves double duty as also being water repellant. Users can also purchase splash guards to protect the sensors from very wet conditions.

Sensor Technology

Each sensor is crafted with stainless steel and housed in cast aluminum (stainless steel housing is available for some sensors). The Direct Connect Sensors are available in 2 forms: explosion proof and non-explosion proof. The explosion proof sensors are available as catalytic sensors for LEL, and LEL H2 specific. For hydrogen sulfide and carbon monoxide, the sensors utilize electrochemical technology which provides incredibly specific accuracy and quick response. Oxygen sensors work with galvanic technology, and infrared sensors for methane, hydrocarbons, and carbon dioxide. Non-explosion proof uses a galvanic sensor for oxygen; electrochemical sensors for hydrogen sulfide, carbon monoxide and other toxic gases; and infrared for carbon dioxide. Both explosion proof and non-explosion proof have 1 year warranties for materials and craftsmanship.

Specifications

The response times are under 30 seconds for all gases except hydrogen sulfide and carbon monoxide in the non-explosion versions (with a response time of 35 seconds) and non-explosion proof model sensor for toxic gases which has a 60 second response time. The life expectancy of all sensors are between 2 and 5 years.

The Direct Connect Sensors are compatible with several RKI Industries' accessories including calibration adaptors, flow through adaptors, remote horns and lights, calibration kits, battery backups, splash guards, air aspirator adaptors, and dataloggers.

72-2120-301 Digester Gas Monitor, 100% Volume CH4/25% Volume O2/1,000 ppm H2S by RKI Instruments

RKI is proud to introduce our Digester Gas Monitor. Gas from waste digesters contains high levels of methane, CO2, and H2S, with little to no oxygen present. The RKI gas monitor checks for all these gases on a cyclic basis. A powerful air aspirator draws a sample from up to 100 feet away. Since digester gas contains high humidity and high H2S, both of which can cause damage to sampling systems, the RKI Digester Gas Monitor is designed to handle these with no damage to the sampling system or sensors. The sample is passed through a series of dirt, dust, and moisture stopping filters, and these filters are automatically purged with fresh air at the end of each cycle.

Measurement time is just 4 minutes, taken at periodic cycles. Cycle time is selectable, with settings for cycle time of 15 minute, 1 hour, 4 hours, 8 hours, or 24 hours. A cycle can also be initiated anytime by pressing a button. After each cycle, the sensors and sampling system are flushed with fresh air so as to minimize corrosion caused by the high H2S content. The system is fault tolerant minimizing the possibility of expensive repairs or downtime.

System integrity is maintained at all times using a flow fail monitoring device which provides a fail alarm and relay if there is ever a problem with the flow system, such as a blockage, or if the air aspirator compressed air supply is removed or interrupted.

The system is housed in a wall mounting NEMA 4X enclosure. The gas readings can be viewed through the enclosure door clear window. Flow meters and filters are easily visible for confirmation of correct flows and operation. The RKI Digester Gas Monitor contains adjustable alarm levels for each gas, and also programmable alarm relays. In addition, the unit provides 4-20mA signals for each gas concentration for connection to an external DCS, PLC, or other site control system. A Modbus output is also available. The outputs are the readings received from the last cycle taken.

Features:

• Corrosion resistant design; Housing designed for extreme environments; Internal construction for extreme samples; Flow system designed to handle corrosive wet samples
• Sample system designed to handle high humidity
• Accurately measures gases with high levels of H2S present
• 100 ft. sample range
• Up to 4 sensors: Methane 0-100% Volume; CO2 0-50% Volume; Oxygen 0-25% Volume; H2S 0-1000 PPM (0-3000 or 0-5000 optional)
• Self draining moisture trap
• Automatic backflush of sampling system
• Long life air aspirator (no moving parts)
• Suitable for inside/outside installations
• NEMA 4X enclosure
• Uses proven RKI technology
• Modular design easy to maintain
• Simple to operate

Industry Applications:

• Wastewater Treatment Digesters
• Biogas Methane
• Animal Farms

30-0954RK-201 Aspirator Panel for One LEL M2 Transmitter, with Flow Switch by RKI Instruments

Single or dual sensor system is designed to monitor gas atmospheres from extreme conditions with either temperature, moisture, or pressure challenges. A powerful air aspirator can pull a sample from up to 100 feet away. The filtered and conditioned sample gas is then passed across one or two different detectors. Each detector shares a common calibration and compressed air inlet for aspirated flow. This system is fault tolerant removing the need for expensive downtime and maintenance. The sample is diluted with air after the gas sensor and then returned to a common exhaust reducing the danger of potential hazardous gases entering a safe work space.

System integrity is maintained at all times using a flow fail monitoring device which provides a NO contact that activates if the sample line becomes blocked or damaged or if the air supply is removed or interrupted.

The panel can be used with direct-connect (sensors connected to an RKI controller), or with S2 Series, and M2 Series transmitters. All transmitters have a 4-20 mA signal for direct connection to the site DCS, PLC or site control system. If needed, RKI instruments can supply a dedicated Gas Detection Control system to provide local alarms, 4-20 mA output with a wide range of dry contacts, making the system very sophisticated and user friendly.

Integral sample filter included to remove water and dirt, automatic drain type.
