Flash Type UV Open Path Gas Detector

The UV Open Path (Line Of Sight) Gas Detection System provides sensitive (PPM level) monitoring of Hydrogen Sulfide (H2S), Ammonia and Aromatic gases.

The 3560-4XX (Spectrex SafEye Model 400) Open Path (line of sight) Gas Detector monitors toxic and aromatic gases at low concentrations over an optical path of up to 330ft (100m). The system has a fast response time of up to 10 seconds.

With its unique flashing light source, SafEye open path gas detector is immune to false alarms, which can be caused by direct or reflected radiation from sunlight, flares, illumination and other "black body" radiation sources.

The UV gas detection system can be used in highly sensitive areas to detect low gas concentration levels or in industrial applications where alarm condition is activated only when specific hazardous concentration levels are exceeded.

The 3560-4XX, due to its special optics design, provides for an alignment tolerance of ±1/2° in all directions and is protected against false gas reading and alarms which are caused by partial obscuration and blocking, misalignment, vibration, flexing or tilts.

The SafEye unique flash source gives a very powerful radiation signal (10KW in a flicker frequency of 1- 100KHz) for a very short time, less than one millisecond at pre-selected intervals. This patented feature enables the detector to address only the high intensity and ultra fast signals that correspond to fast changes in gas concentration, while ignoring all other background radiation.

An optional RS-485 output provides data communication for a single system or a network (as many as 64 detectors) to a host computer for central monitoring.

The SafEye system contains built-in temperature sensors located in the gas sensor compartment. Each SafEye unit is factory calibrated through the entire operating temperature range. The temperature compensating mechanism allows correct operation in changing and extreme temperatures while maintaining the system's accuracy. Its internal microprocessor will automatically compensate for low signals with its internal Automatic Gain Control (AGC).
