Quasar 900 is totally immune to interference from sunlight or any other sources of radiation such as flare stacks, arc welding or lightning.
PERFORMANCE IN ALL WEATHERS The Quasars 900’s high power xenon lamp will compensate for changing weather conditions, including rain, fog, mist, snow and makes it immune to influences from solar radiation, arcwelding, stack flares or vibration from machinery. The optical lenses are thermostatically heated to prevent the formation of ice and build up of snow on the optics even under severe weather conditions. It also eliminates build up of condensation on the lenses. Quasar is rated for operation over a very wide temperature range from -67°F to + 149ºF (-55ºC to + 65ºC) - a truly worldwide product
RELIABILITY Quasar 900 is approved to SIL2 (IEC61508), equipped with heated optics and tolerates a very wide temperature range to provide reliable detection
FAILSAFE No unrevealed failures. In normal operation, the output signal is 4 to 20 mA, depending on the measured gas concentration. Sub-4mA signals includes indications for beam blockage (2mA), a fault (1mA). In addition, a continuous self-test of the Quasar 900 will issue a pre-warning signal (3mA) where the detector is still operational but requires some attention – for example when the transmitter or receiver is misaligned or if there is a deposit build-up on the optics. Maintenance without downtime!
BUILT-IN DATA LOGGER An internal data-logger keeps a detailed record of the previous 100 events.
GAS LIBRARY The detectors can be calibrated to methane, propane or ethylene. The calibration selection must be determined when ordering.
MINIMUM DETECTABLE LEVEL Due to Quasar 900's inherent stability and sensitivity, the minimum detectable level is 0.15 LEL.m
SIMPLE TO ALIGN AND COMMISSION One person can easily align and commission the system without the need for special training or skills. After an initial coarse adjustment by eye, a telescope is fitted allowing fine adjustment to optimized the adjustment for maximum signal strength.
