TOLEDO MUDLOGGING GAS DETECTOR
The TOLEDO MUDLOGGING gas detector is a state of the
art, total combustible hydrocarbon, monitoring system. The system uses two
detectors, a catalytic bead sensor (CC) and a thermal conductivity sensor (TC).
Each sensor has its own amplifier so that each sensor can be zeroed with no
interaction with the other sensor. The gas detector has two outputs one to a
strip chart recorder and the other to the data acquisition computer.
The design has been refined over the years and the
accuracy and reliability is second to none. Calibration is simple and
straightforward and can be easily accomplished in the field by the mud loggers.
CC AMPLIFIER
The CC amplifier is used in the range of 0 to 10%
combustible gas in air. The sensor is a catalytic bead sensor. This sensor is
a coil of wire coated with glass or ceramic material, which is coated with a
catalyst. The coil is electrically heated to a temperature that will allow it
to burn (catalyze) combustible hydrocarbons. When burned, all combustible
hydrocarbons liberate heat proportional to the concentration of the combustible
hydrocarbons present. This heat increases the temperature of the wire coil,
increasing its resistance. The increase in resistance is measured electrically
and is the source of the signal. This signal is amplified and sent to the front
panel meter, a electronic chart recorder and to the data acquisition computer.
TC AMPLIFIER
The TC amplifier is used in the range of 10 to 100%
combustible gas in air. The sensor is a coil of wire that is platinum coated.
The coil of wire is electrically heated to a temperature that is just below the
combustion point of combustible hydrocarbons. When combustible hydrocarbons are
present they will carry off heat from the filament increasing the resistance of
the coil of wire. The increase in resistance is measured electrically and is
the source of the signal. This signal is amplified and sent to the front panel
meter, a electronic chart recorder and to the data acquisition computer.

TOLEDO
MUDLOGGING GAS CHROMATOGRAPH
The TOLEDO MUDLOGGING gas chromatograph is a state of
the art combustible hydrocarbon identification system. It will detect and
indicate the amounts of methane, ethane, propane, iso-butane and normal butane.
The separation of the individual gases is accomplished with a coiled tube filled with
special granules. The gasses, once separated are sent one at a time to a
catalytic bead detector. The output of the detector is amplified and sent to
the front panel indicator, a electronic chart recorder and is available for
connection to an integrator.
The design has been refined over the years and the
accuracy and reliability is second to none. Calibration is simple and
straightforward and can be easily accomplished in the field by the mud loggers.
