10 Teledyne Analytical Instruments

Introduction

1.1 Introduction

The Teledyne Analytical Instruments (TAI) Model 3110 Portable
Trace Oxygen Analyzer is a portable, intrinsically safe oxygen analyzer
capable of analyzing oxygen levels from 2 parts per million (ppm)
oxygen.

The instrument operates from internal rechargeable batteries and is
supplied with a universal AC charge adapter. Featuring quick
disconnect fittings for sample connections and a rugged lightweight
housing with handle, this versatile instrument can be brought to the
sample site and set up for analysis quickly and easily. Because of the
intrinsically safe design, once calibrated, the instrument can be
employed even in hazardous environments without compromise. The
Model 3110 incorporates a large standard feature list designed for
versatile, accurate oxygen analysis for a wide range of applications.
Figure 1-1 shows the standard Model 3110 Portable Trace Oxygen
Analyzer.

The microprocessor based Model 3110 instrument provides user
settable analysis ranges at the trace level. The range can be set from 0-2
ppm to 0-25% oxygen. In auto-ranging mode two ranges can be set and
the analyzer move between these ranges as required. The adjustment
resolution is 0.1 ppm for trace analysis.

Sample oxygen is displayed on a 2-line 20 character alphanumeric
LCD display mounted on the front panel. Four buttons are used to
interface with the instrument and access all of the analyzer features.

Sample gas is introduced and vented via a pair of quick-disconnect
fittings that feature integral shutoff valves that automatically close when
the mating male fitting is withdrawn. The fittings are an integral part of
the measuring cell manifold.

1.2 Features

This instrument is designed to be a versatile analytical instrument
and to perform reliably and accurately in analyzing oxygen
concentrations in gas mixtures from the ppm level through 25% oxygen.
The following features are standard on the Model 3110:

• Data Logger: The optional built-in data logging feature

allows the user to specify the time interval
between data recording sets. The date,
time, and oxygen concentration readings
are stored in internal RAM at the user
specified interval. The data set can be

12 Teledyne Analytical Instruments

downloaded using the instrument’s
optional RS-232 interface.

• Display: A 2-line 20 character alphanumeric LCD

on the front panel displays data and
operational information through various
screens. The contrast is adjustable for
various lighting conditions.

• Four-Button User Interface: Operation is performed using the

four front panel mounted buttons. These
buttons are used to enter data, select items
and move through operational screens that
appear on the display.

• Universal AC Charge Adapter: The rechargeable batteries can

be recharged without removing them from
the instrument. The charger operates over
the range of 100-240 VAC.

• LEDs: Two front panel mounted LEDs are used

to indicate low battery condition and when
the battery is recharging.

• Contrast Control: This feature allows the user to easily

adjust the contrast of the display for
optimum viewing under different lighting
conditions. The adjustment is made using
a front panel control dial.

• Auto-ranging: The user is able to specify two analytical

ranges for analysis in the auto mode. The
Model 3110 will automatically switch
between these ranges depending on the
oxygen level.

• Percent of Range Voltage Output: An optional 0-1 VDC

output is available that represents the
percentage of the current analysis range.

• Real-time Clock: This feature allows the Model 3110 to date

and time stamp the data set recorded on
the data logger. It uses a 24 hour clock.

Teledyne Analytical Instruments 13

• Quick Disconnect Fittings: Dual self-sealing quick disconnect

fittings are installed for making easy
sample connections.

1.3 Method of Analysis

The sample oxygen is measured by a unique electrochemical
transducer which functions as a fuel cell; in this instance, the fuel is
oxygen. Oxygen diffusing into the cell reacts chemically to produce an
electrical current that is proportional to the oxygen concentration in the
gas phase immediately adjacent to the transducer’s sensing surface. The
linear, but minute signal produced by the transducer from oxygen is
amplified by a two-stage amplifier. The O2 sensor output signal is
digitized and fed to the microprocessor. Additional signal conditioning
and temperature compensation are handled electronically and
appropriate signals are directed to the display and output ports.

1.4 Micro-Fuel Cell

The micro-fuel cell (U.S. Pat. Nos. 3,767,552 and 3,668,101) is a
sealed electrochemical transducer with no electrolyte to change or
electrodes to clean. When the cell reaches the end of its useful life, it is
removed, properly disposed of, and replaced with a new cell. The life of
the cell is warranted by TAI (see below).

The cell is specific for oxygen and is not sensitive to flow rate or
reducing agents such as hydrocarbons, carbon monoxide, sulfur dioxide,
etc. In the absence of oxygen, no current is produced; thus, no zeroing is
required.

1.4.1 Cell Warranty

The Class B2-C, A2C, B2C-XL and Insta Trace micro-fuel cells
can be used in the Model 3110 and are warranted for six (6) months
from the date of shipment.

With regard to spare cells, service time starts when the cell is
removed from its shipping package. You should stock only one spare
cell per instrument at a time.

If a cell was working satisfactorily but ceases to function before the
warranty period expires, the sensor will be replaced at no cost.

Introduction Model 3110

14 Teledyne Analytical Instruments

If you have a warranty claim, return the cell in question to the
factory for evaluation. If it is determined that failure is due to faulty
workmanship or material, the cell will be replaced at no cost to you.

WARNING: EVIDENCE OF DAMAGE DUE TO TAMPERING OR

MISHANDLING WILL RENDER THE CELL
WARRANTY NULL AND VOID.

The Model 3110 is designed to meet Factory Mutual standards for
intrinsically safe for Class I, Division I, Groups A, B, C and D
hazardous locations. (Approval pending at time of manual printing.)

This safety feature does not apply when the instrument is being
charged with the 100- 240 VAC external charge adapter. The instrument
should be removed from hazardous areas when the batteries are being
charged.

Note: Do not use the analyzer when the battery charge is low.

1.5 Accuracy and Response

The Model 3110 provides monitoring accuracies of ±2% of full
scale or ±1 ppm, whichever is greater, at constant temperature.

With a sample flow rate of 1 SCFH, a 90% response can be realized
in 60 seconds. The response time on the 3110 is limited by the filter
setting.

1.6 Signal Output

The standard 0-1 VDC output has a 100 ohm impedance and is
suitable for driving external devices that have an input impedance of
10,000 Ω or more. The signal output is available from a port on the rear

panel.

1.7 Compact Packaging

The instrument is housed in 6 1/8" × 9 ½" × 5 5/8" (156 × 241 ×
143 mm) aluminum case that is equipped with a carrying handle and
foot pads. Unlike analog instruments where uneven positioning may
