Gas transmitters TRANSIC100LP

TRANSIC100LP The good nose for oxygen



The good nose for oxygen

Measuring the oxygen in the process can be quite simple. The TRANSIC100LP from SICK is a rugged transmitter that uses tunable diode laser spectroscopy (TDLS) to measure O2 reliably. A technology more common in the world of high-tech analysis is now being used in a field instrument: at an attractive price, easy installation, a long life, low maintenance and suitable for use in explosion-hazardous areas.

At a glance
  • O2 transmitter based on high-performance laser spectroscopy (TDLS)

  • For use in use in explosion-hazardous areas (FM, ATEX and IECEx approvals)

  • Measurement directly in the process or extractive using a measurement gas cell (option)

  • Designed for heavy-duty industrial applications

  • Compact design and easy to operate

  • Long-term stability

  • No moving parts


Fields of applications

  • Monitoring of inert gas blanketing in tanks and vessels

  • O2 measurement in process gases

  • Measurements in potentially explosive atmospheres

  • Process monitoring in fermenters and bioreactors

  • Room air monitoring

  • Quality monitoring for the production of technical gases

  • Replacement of extractive paramagnetic oxygen analyzers and electrochemical cells
