2015   PM-500-2C Pyrometer  2 
DESCRIPTION: 
 
PYROMETER PRINCIPLE:   
This  class  of  temperature  measurement  is  based  on  t he  measurement  of  the  infrared  emission  of  the 
measured  object.  Two  basic  parameters  influence  the   determination  of  the  temperature  from  the 
infrared  radiation:  “    ”  is  the  emissivity  which  depends  on  the  material  itself,  the  shape  and 
roughness of its surface, and then wavelength “   ” at which the radiation is measured.

The  PM-500-2C  uses  two-color  measurement  to  provide   superior  accuracy  in  high  temperature 
applications.  The PM-500-2C pyrometer is ideal in  situations where the target may be obstructed due 
to atmospheric smoke or other particulates, where t he target is moving, or where the target is smaller 
than the field of view.     
Bi-directional,  RS-485  serial  communications  betwee n  the  sensor  and  a  personal  computer  in  the 
control  room  enables  remote  setup,  monitoring,  cali bration,  and  maintenance  which  is  especially 
valuable for installation in hard to reach location s.   Optional laser sighting and high-resolution op tics 
provide a solution for either small targets or long  sight-tubes. 
 
The PM-500-2C is also available with fiber optic ca ble and optical head lens assembly         
(PM-500-2C-FO).

OPTIONS:
 
 
PM-500-2C-FO     
The  PM-500-2C-FO  Fiber  Optic  Pyrometer  consists  of  a  rugged  fiber  optic  cable  with  optical  head 
assembly  connected  to  the  sensor  housing.        The  Op tical  Head  consists  of  a  small  stainless  steel 
cylindrical housing capable of withstanding ambient  temperatures up to 200°C.   The fiber optic cable 
is protected by stainless steel metal armor.
