  • Page 6: General Notes

    The sensors of the optris CX series are non-contact infrared temperature sensors. They calculate the surface temperature based on the emitted infrared energy of objects [►6 Basics of Infrared Thermometry]. The CX sensing head is a sensitive optical system. Please use only the thread for mechanical installation. ...

A change in the temperature of the object is accompanied by a change in the intensity of the radiation. For the measurement of “thermal radiation”...

  • Page 28: Emissivity

    7 Emissivity 7.1 Definition The intensity of infrared radiation, which is emitted by each body, depends on the temperature as well as on the radiation features of the surface material of the measuring object. The emissivity (ε – Epsilon) is used as a material constant factor to describe the ability of the body to emit infrared energy.

  • Page 29: Determination Of Unknown Emissivity

    Emissivity 7.2 Determination of unknown emissivity ► First determine the actual temperature of the measuring object with a thermocouple or contact sensor. Second, measure the temperature with the infrared thermometer and modify the emissivity until the displayed result corresponds to the actual temperature. ►...

  • Page 30: Characteristic Emissivity

    7.3 Characteristic emissivity In case none of the methods mentioned above help to determine the emissivity you may use the emissivity table ►Appendix A – Table of emissivity for metals and Appendix B - Table of emissivity for non-metals. These are average values, only. The actual emissivity of a material depends on the following factors: ...

  • Page 34: Appendix D - Smart Averaging

    Appendix D - Smart Averaging The average function is generally used to smoothen the output signal. With the adjustable parameter time this function can be optimal adjusted to the respective application. One disadvantage of the average function is that fast temperature peaks which are caused by dynamic events are subjected to the same averaging time.
