SICK TRANSIC121LP Laser Oxygen Transmitter
The TRANSIC121LP should only be operated, maintained and inspected by skilled technicians who, based on their technical training and knowledge as well as knowledge of the relevant regulations, especially in potentially explosive atmospheres, can assess the tasks given and recognize the hazards involved.
Purpose of the TRANSIC121LP
The TRANSIC121LP is a stationary oxygen transmitter and serves continuous measurement of oxygen in the industrial sector.
There are 3 variants of the TRANSIC121LP:
1. In-situ measurement
2. Extractive measurement
3. Measurement in ambient air
● The TRANSIC121LP is certified for a process-side operating range from 800 mbar(a) to 1400 mbar(a). Usage with deviating pressures can void the Ex certification.
● The TRANSIC121LP must be operated within the specifications described in the Section Technical Data. The Ex certification becomes void when the TRANSIC121LP is operated outside the specifications.
● The TRANSIC121LP has not been evaluated regarding the safety function as laid out in 2014/34/EU, Annex II, Section 1.5.
The TRANSIC121LP 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.
