SICK ZIRKOR series oxygen analysers

Reliable oxygen measurement is just as important for controlling an optimised combustion process as it is for emissions monitoring. In one of the toughest applications of industrial process automation, the analyser must be easy to integrate and extremely resistant. Optimal combustion, however, relies on perfect dosing. Too little oxygen will result in incomplete combustion and, therefore, increased CO emissions. Too much oxygen, on the other hand, leads to very high heat loss via the exhaust gas.

The ZIRKOR series provides an oxygen reference value for emission measurement to act as a reference for the measurement results. There are three versions available: ZIRKOR100 for smaller plants, ZIRKOR200 for large combustion plants and ZIRKOR302 for adjustment without test gas.

The ZIRKOR100 is rugged due to its integrated cell diagnosis function, which keeps maintenance work to a minimum, with all important information being accessible via ZIRKOR Remote.

The ZIRKOR200 can work in ambient temperatures of up to 1600°C and calibrates itself automatically. Due to its variable probe lengths and a higher number of interfaces, it can be installed in all types of plants and applications, and is certified in accordance with EN 15267.

The main difference between ZIRKOR302 and the other two analysers is its automated calibration using ambient air. The tried-and-tested flow sensor principle does not require any test gases for this calibration and ensures a continuous, exceptionally precise measurement even at high temperatures. The analyser is available with an optional integrated measuring gas pump or an ejector powered by compressed air.
