PhotriX with Fiber Optics connecting to Remote Fixed Focus Lens

This configuration is ideal for applications where the environment near the measurement is unfriendly to the electronic instrumentation, for example processes using induction heating. Available in 4 different infrared spectral responses (880nm, 900nm, 1550nm and 700-1650nm) with temperatures measured between 65 °C and 2600 °C.

Our most accurate pyrometer, the PhotriX Series has the industry’s best signal-to-noise ratio allowing lower temperatures to be measured with unmatched precision for control of high-value processes and research applications. This configuration of our PhotriX series uses a flexible fiber optic cable to connect to a sapphire lightpipe that collects the infrared radiation from the target. This configuration is ideal applications using induction heating or when there is not optical access for a traditional lens solution to have sufficient viewing access to the target.

The Photrix with fiber optics connecting to lightpipe is offered in 4 spectral response (wavelength) versions and has the following features:

• Low Temperature Capability (see chart below for details)
  • 60 to 900 °C or 100 to 1400 °C with 700-1650nm spectral response
  • 100 to 2600 °C with 1550nm spectral response
  • 240 to 2600 °C with 900nm spectral response
  • 250 to 2600 °C with 880nm spectral response 
• Fast Response (1ms)
• Accuracy of +/- 1.5 °C or 0.15% of reading
• Precision of 0.01 °C (see TN-828)

Available options include analog output (user selectable 4-20mA or 0-10V) and multi-channel interface modules allowing up to eight (8) sensors to be integrated into a single digital signal with parallel analog outputs. Standard system includes all necessary electrical cables, power supply, PC interface software and documentation/calibration. 

Typical Applications:

• Induction heated susceptor temperature control
• Solar Thin-film PV substrate measurement during deposition 
• CZ Crystal Growth
