2014  PM-3000 PYROMETER  2  
DESCRIPTION: 
 
The  quality  of  materials  during  the  production  process  is  affected  by  temperature.    Due  to  the 
nature of some of the alloy manufacturing  and produ ction processes  (target aggressiveness, high 
speed motion, etc.), non-contact measuring devices  are required to ensure the correct temperature 
during the production process.    
The  results  provided  by  conventional  optics  pyromet ers  are  influenced  by  several  factors:  non-
linear and unstable relationship between emissivity   and temperature; variations in object surface 
conditions; variations in optical path transmission  due to intermediate media such as dust, smoke 
and  grease  between  the  pyrometer  and  the  measured  o bject;  and  effect  of  light  reflected  from 
external radiation sources.  Another factor that ca uses partial object sighting is the fluctuation of 
objects within optical pyrometer field of view.   
 The  PM-3000  pyrometer  is  specifically  designed  to  overcome  emissivity  variations  and  environment 
problems  and  provide  accurate  continuous  temperatur e  measurements.  This  is  done  by  utilizing 
measurements  of  infrared  radiation  emitted  from  the   target  at  several  wavelengths,  analyzing  the  signal 
and calculating two parameters: 
  Effective Emissivity ( the product of emissivity an d the medium ) 
 True Temperature 
 
PRINCIPLE:  
The pyrometer temperature measurement method utiliz es the fact that objects emit thermal radiation in an 
amount that directly corresponds to their own tempe rature and surface emissivity. 
  
The  pyrometer    detects  the  amount  of  infrared  emitt ed  by  the  measured  object  (target).      The  infrared 
signal  is  analyzed  and  the  temperature  it  represent s  is  analyzed  by  built-in  microprocessor.      The 
calculated  value  is  transmitted  to  a  PLC/PC,  or  dis played  on  the  optional  digital  display.      Below  is a 
block diagram of the system.

SENSOR:    
The  sensor  consists  of  an  optical  system  for  detecting  the  thermal  radiation  that  is  emitted  by  the  object, 
and a microprocessor for processing the signals. 
  A red laser beam that is parallel to the optical pa th shows the target point and enables the user to 
accurately direct the sensor at the measured surfac e. 
 The  sensor  is  supplied  with  50mm  diameter  objective   lens  with  a  focus  setting  of  100mm 
(D50/f100).  It  provides  a  measurement  spot  diameter   of  2cm  at  distance  of  1m  and  wider  spots 
(Distance in mm/50 = spot diameter) for distances. 
  For high temperature application spot diameter = di stance in 400mm

The  precise  placement  of  pyrometers  in  the  extrusio n  line  is  essential  in  achieving  continuous  accurate 
results.    The  PM-3000-SC  scanning  pyrometer  automat ic  aiming  system  ensures  that  the  pyrometer 
camera is automatically locked onto the target at a ll the times – guaranteeing accurate results every time. 
 
FEATURES: 
   Adjustable scanning range up to ± 25° 
   Adjustable scanning step from 0.10 to 5° 
   Adjustable scanning time 
   Minimum working distance: 1 meter 
   Maximum working distance:  dependent on target size  
  
Selection of scanning modes: 
  Hottest point 
   Smooth point 
   Program points (pendulum mode) 
   Continuous scanning (pendulum mode) 
 
APPLICATIONS: 
Billet Furnace Exit / Billet Loader:  
The system  scans the billet along its length, providing the tr ue temperature of the billet skin. The system 
operates in automatic mode and manual. This allows  for temperature monitoring in isothermal extrusion, 
where taper heating/cooling of the billet along its  longitudinal axis is a prerequisite. 
 
Profile Temperature  
The PM-3000-SC scanning pyrometer can be automatica lly or manually aimed at the profile. This feature 
is especially helpful for multi-cavity-dies where e ach profile temperature can be separately detected.  
  
Cooling Table:  
The accurate placement of the pyrometer above the c ooling table has posed difficulties. The PM-3000-SC 
pyrometer  scanner  automatically  locates  the  camera  on  the  profile,  which  may  move  crosswise  on  the 
Running Table, thus ensure an accurate continuous r eading.
