  Non-contact thermometer with new structure for reduced susceptibility to ambient temperature changes

Designed to be less susceptible to ambient temperature changes

• When designing non-contact thermometers that can perform accurate temperature measurements, one of the major challenges is making it them susceptible to ambient temperature changes and to reduce temperature drift.
  OPTEX FA has designed a sensor head that is less susceptible to external and internal temperature changes.

• Dual metal construction

  A dual heat-insulating structure is employed to suppress the effects of external temperature changes, consisting of an aluminum and stainless steel housing (front section) and an aluminum lens barrel covering the thermopile element section.

  

• Circuit board

  By separating the circuit boards, we prevented operational heat and electrical noise from conducting or propagating to the other board that houses the thermopile element.
  This design enables stable and reliable measurements.

  

Stable measurement despite ambient temperature changes

• Temperature measurement in heating and cooling processes is often affected by temperature changes in the installation environment.
  TI-S Series offers more stable measurement continuity than conventional models even when the ambient temperature changes.
  The graph shows the measured temperature and time of a blackbody at 25°C. The sensor head was held in a thermostatic chamber at 50°C for 30 minutes, and then moved to a room temperature environment.

  

• 

• 【Measurement condition】
  ・ Blackbody: 25°C
  ・ Sampling period: 1 s (TI-S30: 2 s)
  ・ Factory default, set Emissivity to “1.0.”
  ・ Ring laser pointer continually ON.
  ・ No change in ambient temperature during blackbody calibration

Equipped with a ring laser pointer

• The ring laser pointer visually indicates the measurement position and measurement field of view.
  Even if part of the target is not within the field of view, it can be adjusted quickly.(Ambient temperature for using ring laser: 0 to 70°C)
  This allows you to make position adjustments easily while checking the measurement field of view, even in dark and small spaces.

First in Industry

Ring laser pointer for visual confirmation of field of view

• Non-contact thermometers that measure infrared energy in the field of view cannot accurately measure temperatures if part of the field of view is outside of the measurement target.
  Conventional laser pointers have only one or two points, so the field of view was not clear. TI-S Series has a ring laser pointer that clearly visualizes the field of view.

  

  

• Flexible installation and easy operation

  

•  Space-saving design allows installation anywhere and easy operation

  

•  High-performance controller with color LCD in multiple languages

  

Calibrate sensor heads directly

• When periodic calibration is required, the controller and sensor head must be removed and rewired each time for devices that are integrated with the controller, which is very time-consuming.
  However, TI-S Series allows sensor heads to be detached from controllers, so they can be calibrated directly.
  Precautions

  

• 

Cable length between sensor head and controller can be extended

• Optional 3 and 10 m extension cables are available.
  These cables are useful when cable lengths need to be changed, such as during layout changes in a factory.
