Benefits
02 | SafEye™ Quasar 950/960
As far as the SafEye™ can see
The fixed open path gas detectors of the SafEye™ Quasar 950 and SafEye™ Quasar 960 series protect bothyour staff and the high risk areas of your plant. The sensors in these detectors are distinguished by their highsensitivity and fast response time. With a range of up to 60 m (197 ft), they reliably measure the concentrationsof the toxic hazardous substances hydrogen sulphide (H2S) and sulphur dioxide (SO2) as well as ammonia(NH3).
Robust and resistant
You can rely on the SafEye™ Quasar 950/960 even in extreme and harsh conditions. The heated lensesprevent a reduction in the measuring performance due to ice build-up and snow accumulations. The detectoralso resists glare and is unaffected by sunlight, natural gas flares, welding arcs and other high intensityradiation. Even strong vibrations cannot harm it.
Complex, but not complicated
The SafEye™ Quasar 950/960 gas detector is a technically complex product – yet it is very easy to use. Itcan easily be installed, aligned, calibrated and configured by one person using the handheld unit (availableseparately).
Compatible with your control system
The SafEye™ Quasar 950/960 is equipped with different output signals. These are compatible with variousindustry-standard protocols such as 0 – 20 mA, HART® and RS485 Modbus. In addition, you can select theperfect model with the required range for your system from a wide selection of available versions. This givesyou greater flexibility in designing the customised security, monitoring and alarm system for your plant. Theapprovals for ATEX, IECEx, TR CU and SIL 2 for SafEye™ 950/960 are available.
