INTRODUCTION
D12EX-IR GAS TRANSMITTER
The D12Ex-IR gas transmitter is used to continuously monitor for leaks of combustible hydrocarbon gas
in ambient air near process tanks, piping, or in enclosed spaces where gases may accumulate. Standard
sensors are available for detecting methane and propane, and numerous other process and solvent gases
like hexane and toluene. Sensors are also available for detecting CO2 with upper ranges of 5000 PPM,
5% by volume, and 100% by volume.
The transmitter features an easily replaceable NDIR (non-dispersive
infrared) sensor “cell”, a non-intrusive four button user interface
with a back-lighted graphics display, three level alarm system with
three (optional) alarm relays, high-resolution 4-20mA current loop
output, real-time clock, data-logger, and optional HART™ or
Modbus™ network interface. The housing is explosion proof, and
is UL rated for use in hazardous locations (see specifications). The
sensor may be located up to 100’ from the transmitter using the
optional remote junction box
Figure 1. D12Ex-IR Gas Transmitter
OPTIONS
The transmitter is available with options to meet the needs of most applications. The “Alarm Relay”
option includes a special power supply board that provides power for three SPDT relays, the display
backlight, and a selectable RS232/485 interface for Modbus™ and ASCII communication. The “HART”
option provides a HART™ FSK interface and may be ordered with or without the Alarm Relay option.
The table below summarizes the available options.
Table 1 Transmitter Options

Description
Remote Sensor Junction Box
Permits the gas sensor to be located up to 100 feet from the transmitter
using only 4 wires.

IR SENSOR
The IR sensor consists of the IR cell mounted within an explosion-proof, stainless steel housing. The
base of the housing is threaded into the transmitter, or (optional) remote housing, and connects the cell to
the transmitter’s electronics. The housing cover threads onto the base and is fitted with a flame arrestor,
which permits gas to reach the cell while preventing ignition of any combustible atmosphere that could
develop around the transmitter. The cover may be removed to replace the cell, if the need should arise.

IR Sensor Versions
The table lists the gas sensors available for the D12Ex-IR.
Sensors are not safe for monitoring acetylene.
Table 2. IR Sensor Versions.
Version
Description
HC
Low level hydrocarbon sensor designed for
detecting methane, propane, and various other
flammable gases in air, below their respective LEL.
Also includes a high range setting for monitoring
methane above its UEL.
HHC
High range hydrocarbon sensor designed for 0-100
%VOL concentrations of Propane, Butane, LPAGE,
etc, for monitoring levels above the UEL.
CO2-L
Carbon dioxide sensor designed for lower ranges.
CO2-H
Carbon dioxide sensor designed for higher ranges.
HC LEL Range Hydrocarbon Sensor
The HC version of the IR sensor is designed for detecting leaks of methane, propane, and other
gases in locations where they might occur, but are not normally expected. The NDIR sensor does
not distinguish one gas from another, but is calibrated to report levels of the selected “target gas”,
much like a catalytic bead sensor. Unlike a catalytic bead sensor, compounds of silicon do not
poison the sensor, nor does the output decrease when exposed to higher levels of gas. Although
not entirely accurate above the target gas LEL, readings will not decrease when exposed to higher
concentrations of the target gas. By default, the transmitter will alarm when the gas level rises
to 20 and 50 percent of the LEL1.
The HC sensor may also be used for monitoring high levels of methane in locations where it is
normally expected. This is accomplished by selecting the “Methane-HR” setting, which should
only be used for monitoring methane at levels above its UEL2(15 %VOL). Extreme care must be
taken in these locations, since a leak of air could produce an explosive atmosphere.
Many hydrocarbon gases have absorption characteristics that are similar to propane. This allows
gas readings to be produced by scaling the propane reading using a “k-factor”. The transmitter
exposes a collection of these gases for selection as the target gas and maintains the k-factor for
each. When span calibrated to the target gas, the transmitter adjusts the k-factor. The transmitter
also permits span calibration to propane as a “surrogate” gas, when the target gas is unavailable.
The table below summarizes target gas selections available on the sensor.
1LEL (Lower Explosive Limit) of a gas or vapor is defined as the lowest percent by volume of that gas or vapor in air that is
capable of producing a flash of fire in presence of an ignition source (arc, flame, heat). Example: 100 %LEL of methane is 5
%VOL in air.
2Highest %VOL (percent by volume) concentration of a gas or a vapor in air capable of producing a flash of fire in presence of
an ignition source (arc, flame, heat).

For safety, when displaying concentrations in units of %LEL, the transmitter’s high-high alarm, “Alarm”
restricts its Type and Reset settings to High and Manu, respectively. The “Warning” and “Caution”
alarms are not restricted, and no alarm may be set above 60 %LEL. The table below lists the alarm
settings. For information about how these settings affect gas alarm operation, see Flammable and Toxic

Methane-HR
The “Methane-HR” setting should be selected only for monitoring methane at levels above the UEL
(Upper Explosive Limit), which is defined as the highest %VOL concentration of a gas or a vapor, in air,
capable of producing a flash of fire in presence of an ignition source (arc, flame, heat). For methane, the
UEL is 15 %VOL. Extreme care must be taken in these locations, since any leak of air can produce an
explosive atmosphere. The table below lists the alarm settings. For information about how these settings
affect gas alarm operation, see Flammable and Toxic Gas Alarms on page 46.
This setting is not designed for use
below the UEL of methane.
