On-Site Quasar Preventative Solutions



LumaSense Technologies, Inc. can schedule to have an experienced and dedicated Field Service Engineer come out to your site to perform field commissioning and inspection. This includes troubleshooting and field verification of calibration of your E2T Quasar Flare Monitoring Systems.

The E2T Quasar 8100 series are monitoring and detection instruments designed for continuous monitoring of pilot flame (type PM), flared gases (type FM), and smoke level (type SM) from flares.

Continuous monitoring of pilot flames and flared gases is critical to ensure that the gases will be ignited for proper compliance with governmentset pilot status recording requirements. Thermocouple failure, flame movement, varying luminosity, and adverse climatic conditions are just a few of the obstacles that have to be overcome to gain longterm monitoring reliability without false alarms.

Periodic maintenance of Quasar systems is essential to ensure correct alignment, clean optics, and proper functionality.LumaSense can design a monthly, quarterly, or semiannual service that is tailored to your operations and specific needs.

Optical and Purge Check
A clear optical path is critical to ensure correct detection of flames.

Flame-path windows and o-rings will be inspected, and cleaned or replaced as necessary. Instrument alignment and focus will be adjusted. Gain and time delay settings as well as mA output will be checked.

It is important that the purge rate is correct for the sight tube to keep the window clean. The purge rate will be checked and adjusted to ensure proper flow.

Current Output and Chopper Motor Check
The Quasar chassis or electronics module will be removed from the EXP housing and taken to a clean work area to be thoroughly checked and tested.

Chopper motor failure is the leading cause of failure in Quasars. All dc voltages will be checked and the chopper motor will be inspected. Chopper motor replacement will be recommended if warranted. The correct chopper motor speed will be verified. The mA output will be measured and adjusted to spec. The NO and NC relay contacts will be checked to ensure reliable switching.

Final Alignment, Focus, and Adjustments
When the Quasar module is re-installed in the housing, it will be properly aligned, focused, and aimed at the target. Finally, the gain and time delay will be properly adjusted and the Quasar will be given a final test.
