VIREX Infra-red Flame Detector(Atex)

 

Double infrared sensor which permit to measure the exclusive presence of CO2 signature from visible flame. It needs a dedicated base SVEX.

CE 0081 II 1 G Eex ia IIC T6/ LCIE 03 ATEX 6349 X

The protection system consists in limiting the energy available in the dangerous atmosphere in such a way that the combustion of the ambient gaseous mixture cannot occur, even in abnormal conditions of use.

VIREx detectors in combination with a Zener barrier and complying with a special connection mode form an intrinsic safety system.

The VIREx is designed to monitor premises with explosible atmospheres whatever the degree of danger, in accordance with CEI 79-10 (zone 0, zone 1 or zone 2) 

ELECTRİC CHARACTERISTICS

The product is classified intrinsic safety for a limited power supply with maximum intensity characteristics of : 28 Vdcs - 110mA.

SENSITIVITY

Detector sensitivity is adjustable with a special tool. This means the 3 classes defined for the 2 types of fires in standard EN54-10 can be obtained :

class 1 : distance ³ 25 m,

class 2 : distance ³ 17 m and implicitly class 3: distance >12 m.

The VIREx is set for class 2 on roll-out.

This means the user can opt for class 1 or 2, by changing the threshold using the "T.E.A.".

CONE OF VISION

The angle of vision within the meaning of standard EN54-10 is ±30° around the optical axis of the detector.

It is ±45° around the optical axis of the detector at maximum mid-distance.
