2015 Temperature Sensors Forecast

  1. 1.   Temperature@lert Temperature Sensors:2015 Forecast
  2. 2. Market Watch: Types of Temperature Sensors !  By  Category:   !  Contact     !  Integrated  Circuits  (ICs)     !  Thermistors     !  Resistant  Temperature     Detectors  (RTDs)   !  Thermocouples   !  Non-­‐Contact     !  Infrared   !  Thermopile       !  By  Materials:   !  Metals   !  Nickel   !  Platinum   !  Copper   !  Silicon   !  Tungsten     !  Alloys      
  3. 3. Contact Sensors {Are in physical contact with the substance/object} !  Advantages:   !  Wide  application  range   !  Relatively  accurate   !  Simple  to  use   !  Economical   !  Disadvantages:   !  requires  physical  contact   !  slower  to  respond  than     non-­‐contact   !  may  damage/contaminate    
  4. 4. Integrated Circuits (ICs) An  IC  sensor  uses  a  small  temperature  transducer  to  convert   temperature  input  into  a  proportional  current  output     Characteristics   !  Small,  accurate  and  inexpensive     !  Reads  temperatures  within  a  55°  to  150°C  range  
  5. 5. Thermistors Thermistors  exhibit  a  large  change  in  resistance   proportional  to  a  small  change  in  temperature.  Types  of   thermistors  include:   !  Positive  temperature  coefRicient  (PTC)  shows  an  increase   of  resistance  with  increasing  temperature   !  Negative  temperature  coefRicient  (NTC)  shows  a   decrease  of  resistance  with  increasing  temperature   Characteristics   !  Limited  temperature   range  (-­‐90°C  to  130°C)   !  Costs  less  than  RTDs   !  High  resistance    
  6. 6. Resistant Temperature Detectors Different  metals  are  used  to  build  RTDs.  The  measurement  is  done   by  linearly  correlating  the  resistance  of  the  RTD  element  with   temperature.       In  other  words:  current  passes  through  the  RTD  device  and  it   generates  voltage;  by  measuring  the  voltage  one  could  determine   the  resistance  and,  thus,  the  object’s  temperature.       Characteristics   !  Resistance  is  between  -­‐260°C  to  630°C   !  Uses  different  metals   !  Linearity  (more  linear  curve)   !  Cheaper  system  wiring  cost   !  Area  sensing  instead  of     1  point  measurements  
  7. 7. Thermocouples Voltage  devices  that  convert  units  of  heat  into  usable  units.  In   other  words,  thermocouples  measure  changes  in  voltage     Characteristics   !  Fast  response  to  temperature  changes   !  Rugged,  inexpensive,  and  simply  constructed   !  Most  widely  used  in  devices   !  Suited  to  read  temperatures  between  -­‐200°C  and  2316°C  
  8. 8. Contact Sensors: Summary Points !  Thermocouples  are  best  suited  to  high  temperatures,   environmental  extremes,  or  applications  requiring   microscopic  size  sensors     !  RTDs  are  best  for  most  industrial  measurements  over   a  wide  temperature  range,  especially  when  sensor   stability  is  essential  for  proper  control     !  Thermistors  are  best  for  low  cost  applications  within   limited  temperature  ranges  
  9. 9. Non-Contact Sensors {Intercept & convert emitted infrared heat into a voltage signal} !  Advantages:   !  React  &  register  faster  than   contact  sensors   !  Can  monitor  moving  objects     !  Isn’t  intrusive   !  Doesn’t  contaminate   !  Disadvantages:   !  Will  not  measure  gas   temperatures   !  Emissivity  variations   !  Field-­‐of-­‐view  restrictions   !  Interference  of  ambient/ environmental  factors  or   temperature  changes  
  10. 10. When to Use Non-Contact !  Non-­‐contact  sensors  are  optimal  to  measure  objects   that  are:   ! Moving     ! Above  the  melting  point  of  other  sensors   ! Mechanically  or  chemically  hostile   ! When  the  distance  is  too  big  to  run  wires    
  11. 11. Infrared !  Infrared  non-­‐contact  sensors:   Allow  users  to  measure  the   temperature  of  an  object  without   needing  physical  contact  with  it     !   How  does  it  work?   Through  the  object’s  thermal   radiant  power,  the  infrared   sensor  is  able  to  measure  the   temperature  that  is  emitted   from  the  object’s  surface  
  12. 12. Thermopiles   !  Rely  on  the  heating  effect  of  absorbed  radiation   !  These  sensors  lack  the  sensitivity  and  speed  of  infrared  detectors  
  13. 13. Non-Contact Sensors: Summary Points !  Infrared  sensors  measure  the  energy  radiated  from   an  object,  without  touching  it     !  Faster  than  contact  sensors:  no  delay  while  the  sensor   reaches  the  correct  temperature     !  Provides  a  faster  and  more  accurate  non-­‐contact   temperature  measurement  and  allows  for  tighter   control  of  your  processes
