Case

The EAGLE 2’s sturdy, high-impact plastic case is radio frequency (RF) resistant and is suitable for use in many environmental conditi ons, indoors and out. The case is dust proof and water resistant. It’s two main components, the top case and bottom case, are held together with three screws located on the bottom case. The interface between the top case and bottom case is gasketed. A sturdy, well balanced handle on the top case allows you to hold the instrument comfortably. A cle ar plastic window is locat ed on the top case to the front of the handle for viewing the LCD.

A removable battery case is located at the rear of the bottom case. A thumbscrew secures the battery case to the bottom case. The interface between the battery case and the bottom case is gasketed. Six raised feet on the bottom of the case, four on the bottom case and two on the battery compartment, raise the EAGLE 2 slightly from the surface on which it rests.

Sensors

The EAGLE 2 uses up to six sensors to monitor combustible gas, oxygen

), carbon monoxide (CO), hydrogen sulfide (H2S), and various other toxic

gases simultaneously. The sensors are located inside the EAGLE 2 bottom case and are installed in the flow chamber. The sensors described below are the four standard sensors. See “Appendix D: PID Sensors” for a description of the PID sensors, “Appendix E: ESM-01 Toxic Sensors” for a description of the ESM-01 toxic sensors, “Appendix F: TC Sensors” for a description of the TC sensors, “Appendix G: Infrared Carbon Dioxide Sensors” for a description of the IR CO

for a description of the IR methane sensors, and “Appendix I: Infrared Hydrocarbon Sensor” for a description of the IR hydrocarbon sensor. The standard sensors use different detection principles as described below.

sensors, “Appendix H: Infrared Methane Sensor”

Catalytic Combustible Gas Sensor (LEL Sensor)

The catalytic combustible gas (LEL) sensor detects combustible gas in the %LEL range. It uses a catalytic element for detection. The reaction of gas with oxygen on the catalyst causes a change in the resistance of the element which changes the current flowing through it. The current is amplified by the EAGLE 2’s circuitry, converted to a measurement of combustible gas concentration, and displayed on the LCD.

The LEL sensor housing includes a sintered metal flame arrestor on one end that allows gas to diffuse into the sensor. On the other end, five pins extend from the sensor. The sensor cable connects to these pins on one end and terminates in a four-position connector on the other end which plugs into the HC socket on the main PCB (see “Main PCB” on page 12).

8 • I n s t r u m e n t D e s cri p t i o n EAGLE 2 Operator’s Manual

Oxygen Sensor

The O2 sensor is a galvanic type of sensor. A membrane behind the openings on the sensor face allows gas to diffuse into the sensor at a rate proportional

to the partial pressure of oxygen. The oxygen reacts in the sensor and produces a voltage proportional to the concentration of oxygen. The voltage is measured by the EAGLE 2’s circuitry, converted to a measurement of gas concentration, and displayed on the LCD.

The sensor includes a short cable that terminates in a round 7-position connector . It m ates wit h the OXY pins on the main PCB (see “Main PCB” on page 12).

CO and H2S Sensors

The CO and H2S sensors are electrochemical sensors that consist of three precious metal electrodes in a dilute acid electrolyte. A gas permeable

membrane covers the sensor face and allows gas to diffuse into the electrolyte. The gas reacts in the sensor and produces a current proportional to the concentration of the target gas. The current is amplified by the EAGLE 2’ s circuitry, converted to a measurement of gas concentration, and displayed on the LCD.

The CO and H

S sensors are physically very similar. Except for their

markings and wire colors, they look almost identical. A three-position connector at the end of a 2-wire cable from each sensor plugs into a socket on the main PCB. The sockets on the main PCB for the CO and H

S sensors a r e

labeled CO and H2S. Normally, the CO connector plugs into the CO socket and the H2S plugs into the H2S socket. However, because of the way that the main PCB circuitry is arranged, if the CO sensor is plugged into the H2S socket and the H2S sensor is plugged into the CO socket, the sensors will still operate properly and the CO and H2S readings will still appear on the channels that are programmed for those gases.

LCD

A digital LCD (liquid crystal display) is visible through a clear plastic window in the top case. The LCD simultaneously shows the gas reading for all installed sensors. The LCD also shows information for each of the EAGLE 2’s operating modes.

Battery Case & Batteries

Four C-size alkaline batteries (standard) or optional rechargeable C-size Ni-MH batteries power the EAGLE 2. They are ins talled in the battery case which is located at the rear of the bottom case. The battery case is secured to the bottom case with a thumbscrew.

Instrument run time is dependent upon battery type. At 25°C, alkaline batteries power the EAGLE 2 for 16 hours of non-alarm operation. Ni-MH batteries will power the EAGLE 2 for 18 hours of non-alarm operation. The current battery voltage is viewable in Display Mode (see “Display Mode” on page 40).

When the EAGLE 2 detects low battery voltage, a low battery warning is activated. When battery voltage is too low for operation, the EAGLE 2 sounds a dead battery alarm.

The alkaline or Ni-MH batteries can be accessed for replacement by unscrewing the thumbscrew that secures the battery case to the bottom case and pulling the battery case away from t he bottom case. The Ni-MH bat teries can be recharged by using the EAGLE 2 charger (see “Replacing or Recharging the Batteries” on page 72).

NOTE: Use of batteries or battery chargers not specified by RKI

Instruments, Inc. will void the CSA classification and may void the warranty.

WARNING: To prevent ignition of a hazardous atmosphere, batteries

must only be changed or charged in an area known to be nonhazardous.

EAGLE 2 Operator’s Manual Instrument Description • 13

Flow System

The EAGLE 2 flow system consists of the inlet fitting, hydrophobic filter, pump, internal tubing, differential pressure (DP) switch, sensor chamber, charcoal filter, and exhaust fitting.

Inlet Fitting

The inlet fitting is on the right front (when viewed from the front) of the bottom case. It is a nickel plated brass quick connect fitting. It mates with either the sample hose or with the hydrophobic probe.

Hydrophobic Filter

The hydrophobic filter is located in the bottom case above the sensors. Normally the hydrophobic probe accessory (see “Hose and Probe” on page 15) will prevent water and particulate contamination from entering the flow system, but if the probe is not used, the hydrophobic filter will stop water and particulates from penetrating further into the flow system. If it becomes dirty or water logged, replace it (see “Replacing the Hydrophobic Filter” on page 77).

Pump

A diaphragm pump ins ide the rear of the bot tom case draws the sample to the sensors. It can draw sample from as far as 125 feet from the EAGLE 2.

CAUTION: Sample hose lengths of more than 125 feet are not r ecommended

for the EAGLE 2 because of flow rate reduction and increased response time. Consult RKI Instruments, Inc. for sample hose lengths longer than 125 feet.

Internal Tubing

The flow system includes polyurethane tubing to route the sample between the various components of the flow system. The internal sample tubing is not user serviceable.

Differential Pressure (DP) Switch The DP switch is inside the front of the bottom case. It senses the EAGLE 2’ s

flowrate by monitoring the pressure drop between points in the flow system. When the flowrate becomes too low for safe operation of the EAGLE 2, a set of contacts inside it open and the EAGLE 2 indicates a low flow alarm.

Sensor Chamber

A PVC block in the bottom case is configured to accept the four gas sensors. It routes the sample to each sensor. The LEL sensor and the oxygen sensor are retained in the sensor chamber by brackets. The CO and H

S sensors are

each pushed past two sealing O-rings into the chamber and are retained by

14 • I n s t r u m e n t D e scr i p t i o n EAGLE 2 Operator’s Manual

the O-ring compression force.

Charcoal Filter

The charcoal filter is located in the front of the flow chamber next to the CO sensor . It contains activated charcoal. The CO sensor will respond if exposed to H

S and certain hydrocarbon gases. The charcoal filter scrubs these gases

out of the sample to avoid fal se CO readings. If false or elevated CO readings are noticed, especially in the pres ence of H

charcoal inside the filter cannot be replaced; the entire filter must be replaced.

Exhaust Fitting

The exhaust fitting is located below the inlet fitting. It routes the gas sample out of the EAGLE 2. It includes a female 10-32 thread that can be used for the installation of a hose barb or other type of fitting that has a male 10-32 thread so that the exhaust can be routed to a particular location with flexible tubing if desired.

Standard Accessories

S, change the charcoal filter. The

Standard accessories include the shoulder strap, the sample hose, and the hydrophobic probe.

Shoulder Strap

A comfortable elastic shoulder strap clips to the EAGLE 2 at the front and rear of the top c ase. It clips to s tainless steel ri ngs that a re install ed in feat ures on the top case. It can be removed from the EAGLE 2 by opening the clip at each end of the strap and removing it from the strap ring at the front and rear of the top case.

Hose and Probe

A 5 foot polyurethane sample hose and a 10 inch hydrophobic probe are included as standard. The hose has a male quick connect fitting on one end and a female quick connect fitting on the other end. The probe has a male quick connect fitting. Normally, the male end of sample hose is installed in the EAGLE 2 inlet fitting and the probe is installed in the female end of the hose. However, if the sample hose is not needed for monitoring a particular area, the probe may be installed directly to the inlet fitting. Sample hose lengths are available from 5 feet (standard length) to 125 feet (see “General Parts List” on page 84). A teflon lined hose is provided with all units that contain a PID sensor. This hose must be used when operating a PID EAGLE 2 (see “Appendix D: PID Sensors” on page 136).

CAUTION: Sample hose lengths of more than 125 feet are not r ecommended

for the EAGLE 2 because of flow rate reduction and increased response time. Consult RKI Instruments, Inc. for hose lengths longer than 125 feet.

The probe includes a replaceable particle filter and hydrophobic filter disk that prevent particulates and water from entering the EAGLE 2’s flow system. See “Replacing the Hydrophobic Probe’s Particle Filter and Hydrophobic Filter Disk” on page 75 for instructions to replace the particle filter and hydrophobic filter disk.

NOTE: When using the probe with a PID EAGLE 2, be sure that th e particle

filter is not installed.

Optional Probes

Various optional probes designed for specific applications are available for the EAGLE 2. They include the following:

• 30 inch aluminum probe

Figure 9: 30 Inch Aluminum Probe

This probe is designed for applications where it is necessary to put the probe tip in areas that are out of reach with the standard probe. A small breather hole near the end of the probe tube prevents interruption of sampling and a low flow alarm if the probe tip is blocked.

18 • O p t i o n a l A c c e s s or i e s EAGLE 2 Operator’s Manual

• 30 inch stainless steel probe

Figure 10: 30 Inch Stainless Steel Probe

This probe is physically the same as the 30 inch aluminum probe and is intended for applications where a high level of corrosion resistance is required in the long probe tube.

• 4 foot stainless steel probe

Figure 11: 4 Foot Stainless Steel Probe

This probe is designed for areas where it is necessary to put the probe tip in areas that are out of reach for even the 30 inch probes. A stainless steel probe tube is used because the length of the probe tube requires a high degree of rigidity. Stainless steel is more rigid than other normally used materials. A small breather hole near the end of the probe tube prevents interruption of sampling and a low flow alarm if the probe tip is blocked.

• Barhole probe

Figure 12: Barhole Probe

This probe is designed specifically for barhole testing. See “Appendix K: Using the EAGLE 2 in Bar Hole Mode” for an in-depth discussion of using the EAGLE 2 in Bar Hole Mode.

• 10 inch probe with dust filter

Figure 13: 10 Inch Probe With Dust Filter

This probe is designed for use where drawing water or moisture into the EAGLE 2 is not a concern. Instead of a hydrophobic filter, a cotton dust filter is used.

• 32 inch telescoping probe with dust filter

This probe is designed for use where it is necessary to put the probe tip in areas not accessible with the 10 inch probe with dust filter and applications where the probe tube must be collapsible for storage.

• 7 foot telescoping probe with dust filter

This probe is designed for use where it is necessary to put the probe tip in areas not accessible with the 32 inch te lescoping probe with dust filter and applications where the probe tube must be collapsible for storage.
