SICK TRANSIC111LP Laser Oxygen Transmitter

SICK TRANSIC111LP Laser Oxygen Transmitter

The TRANSIC111LP is a stationary oxygen measuring device and serves continuous measurement of oxygen in the industrial sector. The TRANSIC111LP probe contains a temperature sensor. This sensor measures the temperature of the sample gas and is used for temperature compensation of the gas to be measured. 

Three application variants of the TRANSIC111LP are available from SICK:

1. In-situ measurement

2. Extractive measurement

3. Measurement in ambient air

The TRANSIC111LP functions using light absorption of a tunable diode laser (Tunable Diode Laser Absorption Spectroscopy TDLAS). The gas concentration is measured using the damping of a laser beam sent from a tunable diode laser source in the gas sample. For oxygen measuring, the laser beam wavelength is set to match one of the characteristic absorption lines of oxygen in the wavelength range of around 760 nm in the near infrared range (NIR) of the electromagnetic spectrum. During measurement, the diode laser beam wavelength is continuously modulated to scan across one of the oxygen absorption lines. This generates a periodic signal in a photodetector, the amplitude of which is proportional

to the amount of oxygen in the laser beam path.
