2.5.5 Detectors 

 

 

a)  Configuration:- 

2 off - Employing reflective cone optical focusing system 

 

 

Coincident fields of view arranged as separate channels 

b)  Field Of View:-   

+5°/-15°(along transit axis path)  +/-38°(across transit path) 

 

Refer to coverage chart in section 

c)  Characteristic 

Spectral Filter :  5 - 14 µm 

 

Sensitivity :  10 - 40 µW 

 

Transit speed : 0.5 to 6 m/s    

 

Response : 80 - 1000 ºC  (170 - 1800 ºF) - See below 

 

NOTE 

#1 

-  Air failure signalled if pressure switch employed. 

Figure 7 indicates the 
correlation between the 
temperature and size of ‘hot 
spot’ anomalies for a typical 
installation to produce one or 
more detector channel 
activations at various trigger 
level settings. 
Exact response is dependant 
on the emissivity factor of the 
monitored material, sensor 
orientation and target speed. 

Specification - Continued
