- Service & Support
The E2T Quasar 2 is available in two models, the Quasar 2 M8100-EXP and Quasar 2 M8100-EXP Advanced. The base system provides basic flare pilot monitoring capabilities and the advanced system includes an intensity mA output. The advanced unit's setpoint feature can also be used for staged flares.
Target alignment is accomplished via the targeting port and signal intensity LED bar displays amplitude in combination with a stable heavy-duty, swivel M-4 mount. Custom electronics adapt to target movement, varying luminosity, and most climate conditions.
- Install a reliable and accurate flare pilot monitoring system without service interruption
- Use the high-resolution optical system and various spot sizes to position the system up to 1/4 mile (400 m) away from the monitored flare stack
- Adjust the alarm delay circuit to eliminate false alarms from temporary loss of signal due to intermittent flames, adverse weather, and wind
- Monitor pilot flame detection and flaring status signals with the intensity mA output (Advanced version only)
- Configurable product to meet a wide range of client flare types and monitoring requirements
- Five optics options with targeting port for alignment (available in 37.5:1, 60:1, 75:1, 150:1, and 300:1)
- Status lights: green (flame) and red (no flame)
- Housing is stainless steel (316 L), 114 mm tube diameter, IP 66
- Additional features are available to meet a wide range of flare types, monitoring requirements, and budgets
