This means that changed parameter settings will be saved in the CT-internal Flash-EEPROM and will also be kept after the sensor is switched off. In case values should be changed quite often or continuously the flash mode can be switched off by using the following command: Decimal:...

  • Page 83: Emissivity

    Emissivity Emissivity 14.1 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 (e – Epsilon) is used as a material constant factor to describe the ability of the body to emit infrared energy.

    Emissivity 14.3 Characteristic Emissivity In the case that none of the methods mentioned above help to determine the emissivity you may use the emissivity tables, see A 3, see A 4. These are only average values. The actual emissivity of a material de- pends on the following factors: - Temperature - Measuring angle...

    Appendix | Smart Averaging Smart Averaging The average function is generally used to smoothen the signal curves. 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.
