This sensor is the successor model for 31460 and 31450.

*Patented thermal conductivity (TC) sensor design
*No sample preparation required, the gas concentration is measured directly in the sample
*Rugged construction can handle harsh plant conditions and high sample pressures
*High temperature resistance to withstand cleaning in place (CIP)
*Fast response time to improve plant productivity
產品介紹
The Orbisphere patented Thermal Conductivity sensor has been developed to give continuous CO2 measurements in gas phase or dissolved in a liquid. The measuring technique is a combination of a gas diffusion membrane and a solid-state gas thermal conductivity detector.
 
A micro volume enclosed between a semi-permeable membrane and a thermal conductivity detector is periodically flushed with a purge gas. After each purge, the gas to be measured diffuses from the sample through the membrane, changing the thermal conductivity of the gas surrounding the detector. A change in thermal conductivity modifies the detector resistivity. This is measured, together with temperature, to calculate the gas concentration.
