RELIABLE MEASUREMENT RESULTS UNDER TOUGH CONDITIONS WITH ZIRKOR OXYGEN ANALYSERS FROM SICK Combining high quality and innovative performance, the ZIRKOR range of oxygen analysers from SICK provides an oxygen reference value for emission measurement to ensure reliable, measurable results. The new range of oxygen analysers in the ZIRKOR series from SICK Automation are extremely rugged and combine high quality with innovative performance. To optimise combustion, the easy to operate and completely reliable precision devices are designed for combustion measurement, which is taken directly after combustion so the oxygen value can be perfectly adapted to the fuel. 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 extremely resistant and easy to integrate. 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 in order to ensure reliable measurement results. There are three versions available, ZIRKOR100 for smaller plants, ZIRKOR200 for large combustion plants, and ZIRKOR302 for adjustment without test gas. Tough performance – easy to operate – precise analysis The ZIRKOR100 is extremely rugged thanks to its innovative cell technology. The integrated cell diagnosis function keeps maintenance work to a minimum and all important information can be accessed via ZIRKOR Remote. The ZIRKOR200 is a high-tech analyser with simple connection options. It can work in ambient temperatures of up to 1 600° C without any problems and calibrates itself automatically. Thanks to its variable probe lengths and a higher number of interfaces, it can be installed in all kinds of plants and applications. The model works in temperatures of up to 600° C and is also certified in accordance with EN 15267. The main difference between ZIRKOR302 and the other two analysers is its automated calibration using ambient air. The triedand-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.

Imagine 10 000 temperature readings, monitored at one central point, using one fibre optic cable! AP Sensing can monitor temperature under harsh conditions over long distances to optimise maintenance, detect fires and overheating, and measure environmental temperature. THE SOLUTION INTEGRATES EASILY INTO YOUR EXISTING MANAGEMENT PLATFORM (SCADA SYSTEMS) BY DRY CONTACTS AND/OR COMMUNICATING DIRECTLY OVER ETHERNET (TCP/IP), USING STANDARD PROTOCOLS. APPLICATIONS INCLUDE: • Temperature monitoring along conveyor belts • Sub-stations • Switchgear cubicles and MCC rooms • Coal bunkers • The inside power cables • Mining tunnels • Cable racks and many more ADVANTAGES: • Accuracy • Ease of installation • Immunity to EMC, dirt, dust and humidity • Very little maintenance over an exceptionally long lifetime • Minimal operational costs • Early warning when events occur UP TO 10KM OF FIBRE OPTIC CABLE CAN BE USED TO SENSE HEAT ON EACH 1M SECTION TO 1°C ACCURACY ENABLING USERS TO MONITOR 10 000 TEMPERATURE READINGS FROM ONE CENTRAL POINT USING ONE 10KM FIBRE OPTIC CABLE. AP SENSING’s linear heat series minimises your operational costs and performs extremely reliable by using a standard fibre optic cable which has no active components or electronic sensors within the exposed zone. Fibre optic cable is also immune to electromagnetic interference. Distributed Temperature Sensing (DTS) utilises laser light and fibre optic cables to measure temperature. An infrared LASER PULSE is sent through the fibre. The incident energy is back-scattered from the glass molecules throughout the entire length of the fibre. These minute light signals contain information about the temperature of the glass at any given point in the fibre, in accordance with the Raman Effect. The back scattered light is measured and then analysed for temperature. The POSITION of the temperature reading (along the fibre length) is determined by measuring the time delay of the returning light pulse, similar to a radar echo.
