1.4  Design and principle of operation 

1.4.1 

Design of the radiometer

 

The  radiometer  (according  to  Figure  1)  is  designed  as  a  rectangular 

parallelepiped rounded  on  each  side.  The plastic  damp  and  dustproof  body  of  the 
radiometer  (ingress  protection  rating  IP54)  consists  of  two  parts  –  upper  (1)  and 
lower (2) covers. The LCD (3), “ALARM” light-emitting diode (4) and two key of 
control MODE (5) and THRESHOLD (6) are located on the panel of the upper cover. 
The printed-circuit board with the electric circuit of the device is screwed with four 
screws to the upper cover of the radiometer. All inscriptions of the upper cover are 
serigraphy applied.
