  • Page 24: Self-Diagnostic

    2.7.2 Self-diagnostic At a supply voltage (Vcc) ≥ 12 V it takes about 5 minutes until the sensor works in a stable mode. Therefore, after switching on the unit, the LED will show a not stable state for up to 5 minutes. With this function the current status of the sensor will be indicated by different flash modes of the LED.

  • Page 37: Digital Communication

    Installation You can choose between an mV output (0-5 or 0-10 V; scalable via software) and a thermocouple output type K. Therefor the optional software is needed. The factory default setting is mV output. ► Factory default settings The thermocouple output supplies a voltage according to the t/c characteristic curve type K. If you want to extend this output you have to use a suitable thermocouple extension cable (NiCr-Ni).

  • Page 52 The specifications of the lens decisively determine the optical path of the infrared thermometer, which is characterized by the ratio Distance to Spot size. The spectral filter selects the wavelength range, which is relevant for the temperature measurement. The detector in cooperation with the processing electronics transforms the emitted infrared radiation into electrical signals.

  • Page 53: Emissivity

    Emissivity 8 Emissivity 8.1 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 54 ► If you monitor temperatures of up to 380°C you may place a special plastic sticker (emissivity dots – Order No.: ACLSED) onto the measuring object, which covers it completely. 1. Set the emissivity to 0.95 and take the temperature of the sticker. 2.

    Smart averaging Appendix B – 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.
