Détecteur linéaire de gaz combustible SafEye Quasar 901
Quasar 901 - Détecteur linéaire de gaz combustible SafEye 7-20m - Spectrex
Détecteur linéaire de gaz, Barrière de détection de gaz, Détecteur de gaz en circuit ouvert
The New SafEye Quasar 900 is an open path detection system which provides continuous monitoring for combustible hydrocarbon gases. It employs “spectral ﬁngerprint” analysis of the atmosphere using the Differential Optical Absorption Spectroscopy (DOAS) technique.
The Quasar 900 consists of a Xenon Flash infrared transmitter and infrared receiver, separated over a line of sight from 23 ft (7m) up to 660 ft (200m) in extremely harsh environments where dust, fog, rain, snow or vibration can cause a high reduction of signal.
The Quasar 900 transmitter and receiver are both housed in a rugged, stainless steel, ATEX and IECEx approved enclosure. The main enclosure is EExd ﬂameproof with an integral, segregated, EExe increased safety terminal section.
The hand-held communication unit can be connected in-situ via the intrinsically safe approved data port for prognostic and diagnostic maintenance. The Quasar 900 is approved to FM/FMC per Class I Div 1 Group B, C and D and Class I, II Div 1 Group E, F and G, and ATEX/IECEx per Ex d e ib [ib Gb] IIB + H2 T4 Gb, Ex tb IIIC T135°C Db.
The Quasar 900 includes heated windows to eliminate condensation and icing, HART capability for digital communication and is designed to meet SIL2 per IEC61508 and FM performance approved per FM6325 and tested per EN60079-29-4.
