 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.
