However, since this is cut out again when the relationship is formed, it is on the other hand not necessary to know it.<\/p>\n<p>However, a prerequisite for an error-free measurement result is an always constant ratio, even if the measurement temperature changes. With many materials, however, the emissivity changes depending on the temperature or even the measurement angle. The further the two measurement wavelengths are apart, the more the ratio changes in such materials when the temperature changes. The measurement deviations are then of different sizes, depending on which temperature is currently being measured. Measuring devices with spectral ranges that are further apart are only suitable for measurements on so-called \"gray radiators\", which are usually not available.<\/p>\n<p class=\"translation-block\">The <strong>measuring wavelengths<\/strong> of Sensortherm's 2-color pyrometers are <strong>close<\/strong> to each other in order to keep this error as low as possible. The individual measurement results of the two spectral ranges are therefore more parallel, which is necessary in order to always correctly calculate the quotient at all measurement temperatures.<\/p>\n<p>[\/et_pb_accordion_item][et_pb_accordion_item title=&#8220;Wann muss ich das Emissionsgradverh\u00e4ltnis einstellen?&#8220; closed_toggle_background_color=&#8220;#f3f4f4&#8243; icon_color=&#8220;#7ea2d5&#8243; _builder_version=&#8220;4.19.2&#8243; _module_preset=&#8220;default&#8220; custom_margin=&#8220;0px||0px||true|false&#8220; custom_padding=&#8220;5px||5px||true|false&#8220; hover_enabled=&#8220;0&#8243; border_radii=&#8220;on|0px|0px|0px|0px&#8220; border_width_all=&#8220;0px&#8220; border_width_top=&#8220;1px&#8220; border_color_top=&#8220;#0b3172&#8243; border_width_bottom=&#8220;1px&#8220; border_color_bottom=&#8220;#0b3172&#8243; global_colors_info=&#8220;{}&#8220; toggle_text_color=&#8220;#7ea2d5&#8243; toggle_level=&#8220;h3&#8243; toggle_font=&#8220;|700|||||||&#8220; open=&#8220;off&#8220; sticky_enabled=&#8220;0&#8243;]<\/p>\n<p>Measurement objects that emit the same at the two wavelengths of the 2-color pyrometer are often described as \"gray body\" (e.g. well-oxidized iron or steel surfaces). They can be measured precisely without correction with the setting 1.00 for the emissivity slope.<br \/>Measuring objects whose emissivity is different at the two wavelengths of the quotient pyrometer (e.g. bare, non-oxidized metal surfaces) require a correction setting for an accurate temperature measurement, the so-called emissivity ratio \u01902 \/ \u01901. The value can be greater or less than 1, depending on whether the emissivity of channel 1 or 2 is higher (gain 1.000\u20130.800; attenuation 1.000\u20131.200).<\/p>\n<p class=\"translation-block\">Regardless of whether the measurement is made with an emissivity slope of 1 or above or below, the ratio must remain constant over the required temperature range. In the <em>SensorTools<\/em> software, the 2-color temperature and that of the two individual channels can be displayed at the same time. If the curves of the two individual channels run uniformly parallel in the required measuring range, the ratio is constant and a 2-color measurement is possible. If the temperature values of the curves are the same (with the same set emissivity), the emissivity ratio is 1. If they run in parallel, the correct value for the emissivity slope must be found, e.g. by a comparison measurement with a thermocouple and subsequent ratio adjustment until the temperatures match.<\/p>\n<p>[\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>","protected":false},"excerpt":{"rendered":"<p>QuotientenpyrometerQuotientenpyrometer messen die Infrarotstrahlung bei zwei nah beieinander liegenden Wellenl\u00e4ngen gleichzeitig und bestimmen die Temperatur durch Quotientenbildung.
