Panametrics In Situ Oxygen Flue Gas
Transmitter

The FGA 311 is a simple, low-cost, in situ, flue gas
oxygen transmitter. The zirconium oxide oxygen sensor is
installed directly into the flue stack or furnace wall. For
low-temperature applications, a heater is included to
maintain a constant temperature on the zirconium oxide
sensor. The FGA 311 is available in both weatherproof
and explosion proof configurations. Typical applications
for the FGA 311 include natural gas-fired utility and
municipal boilers, as well as natural gas-fired process
heaters. The FGA 311 is ideal for boiler and furnace
manufacturers due to its low-cost, basic transmitter
configuration.

Easy Installation

The FGA 311 can be supplied with standard NPT fittings
or it can be mounted on existing process flanges, making
installation quick, easy and inexpensive.

The electrical connections for the FGA 311 are as simple
as 115 to 230 VAC for power and a 4 to 20 mA
output signal.

Easy Configuration

Output ranges for the FGA 311 are user-selectable via a
switch or the RS232 interface to accommodate changing
measurement needs.

Easy Troubleshooting

Users can quickly connect the FGA 311’s RS232 interface
to a PC and view detailed diagnostics via terminal
emulation. The FGA 311’s microprocessor can report
sensor mV output, heater temperature and other system
status information, allowing the user to determine
quickly any necessary corrective action.

Easy Removal and Replacement of
Sensor and Heater Assembly

Particulates and the corrosives of most flue gases are
very harsh to instrumentation located within the process.
Conventional in situ flue gas oxygen transmitters require
removal of the whole analyzer from the sample point to
replace the sensor and heater assembly. The unique
design of the FGA 311 makes the replacement easy. The
cover on the transmitter housing is unscrewed, the wire
harnesses are disconnected, and the sensor and heater
assembly are unscrewed and removed. The sensor and
heater can then slide out. The transmitter housing and
probe remain in place, reducing labor time and effort for
any sensor and heater replacement needs.
