USB-LS-450
The USB-LS-450 module connects to the USB2000-FL Spectrometer via a 10-pin connector on the front
of the spectrometer. The spectrometer provides power to the USB-LS-450, and enables synchronization
functions and I2C communications.
In addition, the USB-LS-450 features a built-in, 24-bit analog-to-digital converter with an analog front
end that is configured for a 100 ohm platinum RTD (resistance temperature device). This is particularly
useful when configured as part of the Fiber Optic Oxygen Sensor. As an added benefit for oxygen probe
users, the USB-LS-450 has on-board memory to store temperature calibration coefficients and oxygen
calibration coefficients.
The USB-LS-450 board allows for software-controlled switching between pulsed and continuous
operation of the LED.
