72-2120-101 Digester Gas Monitor, 100% Volume CH4 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

65-2300RK-CL-10 Sensor, Chlorine (Cl2) Sensor, 0 - 10 ppm, Direct Connection with Conduit Mounting, Non Explosion Proof (No Transmitter, No J-Box) 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.

GD-K71D-HBR GD-K71D Smart Transmitter, Hydrogen Bromide (HBr), 0 - 9 ppm by RKI Instruments

The GD-K71D is a complete sample drawing gas monitor, including digital readout and alarm relays. A new gas sensor technology using an intelligent sensor for remote location calibration and setup is used. The new GD-K71D sensors are designed to provide a longer time period between calibrations. Calibration intervals have been extended to12 months of on-line service which equates to reduced maintenance cost. In addition, the sensors can be calibrated away from the gas detector installation, for example in a service area or off site. This eliminates the inconvenience of having calibration gases in the fab or monitoring location. GD-K71D easily connects to an existing PLC system and is ideal for applications needing a local readout or where a relay control is needed. The automatic zero correction software provides excellent long term stability and minimizes false alarms due to zero drift.

Features:

• LED digital display
• Sensor information and calibration is stored within sensor memory
• Several data transmission options available
• Zero suppression and correction

The new Model GD-70D series smart gas detection transmitter series sets a new standard for performance, flexibility, and versatility. The GD-70D sample-draw transmitter offers an array of sensor technologies unmatched in the industry, including unique offerings, such as our hydrogen-specific ppm and LEL versions.

The long life high capacity pump and wide variety of sensing elements are replaceable in a few seconds, with no tools required! The smart sensors retain all calibration and sensor-specific data in non-volatile memory, so sensor can be hot-swapped in the field with no programming required. The sensors also retain calibration information, which means they can be conveniently calibrated separate from the transmitter, avoiding transport of calibration gases to the field location. The GD-70D firmware automatically corrects for long-term zero and span "drift minimizing maintenance and maximizing reliability.

The GD-70D can be used as a stand-alone device, offering a number of communication protocols to existing PLC systems, or can be integrated with RKI's Beacon series of single and multi-channel controllers.

All GD-70D transmitters include large, easy to read integral LCD display, tri-color bar graph for visual notification of alarm status, programmable low and high alarm relays, and fault relay. Pump flow is self-tuning for maintenance-free operation. Because all GD-70D base units are identical, sensors can be interchanged with no programming or tools required, resulting in maximum flexibility to the user.
