New Infrared Gas Transmitters
Jan 27 2009 Read 975 Times
Accurate and reliable in use, both instruments have demonstrated a precise, stable measuring performance during long-term tests and, as certified by TÜV*, only account for two percent of the SIL 2 budget for a gas detection system.
Incorporating double-compensating, 4-beam technology and designed to detect methane, propane and ethylene as standard, the Dräger PIR 7000 also features a variable gas library which allows up to ten other substances such as solvents or alcohol to be added. Easily adapted to meet the requirements of different industries, the measuring ranges
of both transmitters can be freely configured to suit the needs of different applications.
A special process adapter allows the transmitters’ response characteristics to be changed to meet individual requirements. The response mode can also be configured to suit particular needs with, for instance, the “high speed” option, when combined with low alarm thresholds, providing indication of detected substances in under a second.
Any faults during the measuring operation are immediately shown on the status indicator. Certified to IP 66 and IP 67 and approved for use in potentially explosive atmospheres in accordance with ATEX, IECEx, UL and CSA, these rugged instruments are built for use in the harshest environments. With a wide range of assembly and configuration accessories, they can also be installed in most settings. Reducing the risk of false alarms, the measuring characteristics of the sensors are unaffected by dust and dirt deposits on the optical surfaces, and the
use of mesh and filters prevents insects from entering the measurement cuvette.
Both the Dräger PIR 7000 and Dräger PIR 7200 offer an expected lifetime of more than 15 years with regular servicing.
