RANSMITTER

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

PTIONS

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
