QRI2A2.B180B 红外火焰探测器

品牌:SIEMENS/西门子(原LANDIS&STAEFA)

产地:德国

 

Infrared flame detectors for use with Siemens burner controls, for the supervision of gas, oil or other flames that emit infrared light.

The QRI... are suited for burners of any capacity, either in continuous or intermittent operation.

 

Key features of the QRI... flame detectors:

- Detector with infrared-sensitive flame detecting element

- Integrated flame signal amplifier

- Designed for frontal and lateral (90°) illumination

- Suited for use with burner controls type LMV5...

- Secured to the burner with flange and clamp

 

The spectral sensitivity of the QRI... is a maximum of about 2 μm covering infrared radiation emitted by gas, oil, and coal flames as well as other sources of infrared light. Owing to electronic self-supervision of the flame signal, the QRI... can be used in connection with suitable burner controls designed for burners in continuous or intermittent

operation.

The sensitivity of the QRI... is such that it must be fitted behind the burner’s baffle plate.

 

The QRI... has an impact-proof housing made of black plastic. The lens is fitted in a dust-tight position.

The QRI... can be secured to the burner within its adjusting range, using the clamp and the flange provided.

The 3-core connecting cable is ready connected to the QRI... and features cable strain relief.

Depending on the type of burner construction, there are flame detectors for frontal or lateral illumination available.
