     Model 43i Trace Level-Enhanced Instruction Manual 

Thermo Fisher Scientific 

 

The pressure sensor assembly consists of a board containing an 
instrumentation amplifier and a pressure transducer with a gas input 
fitting. The pressure transducer output is produced by measuring the 
pressure difference between the sample gas pressure and ambient air 
pressure. 

The fluorescence chamber temperature is measured with a thermistor. The 
voltage across the thermistor is fed to the main processor for use in 
calculating and displaying the reaction chamber temperature. The voltage 
across the thermistor is also compared to a set-point voltage and used to 
control that the reaction chamber heaters to maintain a constant 
temperature. 

The PMT power supply produces high voltage to operate the 
photomultiplier tube used in the measurement system. The output voltage 
is adjustable from approximately 600 to 1200 volts under software control. 

The diagnostic LED is used to provide an alternate light source to the 
PMT to determine if the PMT is operating when the operating condition 
of the flash lamp is unknown. 

The input board accepts the current signal from the PMT and converts it 
to a voltage, which is scaled by a factor of approximately 1, 10, or 100 
depending on the full-scale range of the SO

2

 channel. The scaled voltage 

signal is converted to a frequency and sent to the microprocessor. 

The digital output board connects to the motherboard and provides 
solenoid driver outputs and relay contact outputs to a connector located on 
the rear panel of the instrument. Ten relay contacts normally open (with 
power off) are provided which are electrically isolated from each other. 
Eight solenoid driver outputs (open collector) are provided along with a 
corresp24VDC supply pin on the connector. 

 

The front panel connector board interfaces between the motherboard and 
the front panel mounted function key panel and Graphics display. It serves 
as central location to tie the three connectors required for the function key 
panel, the graphics display control lines, and the graphics display backlight 
to a single ribbon cable extending back to the motherboard. This board
