They are particularly well-suited for applications involving wide temperature ranges, harsh environmental conditions, and compact sensor designs. Typical applications include machinery and equipment, test benches, furnace applications, process measurement technology, and laboratory set-ups. <\/p>\n
However, the quality of the measurement depends not only on the probe itself, but also on the correct selection of the thermocouple type, cold junction compensation, and the proper evaluation of the sensor signal. A thermocouple does not directly provide an absolute temperature, but rather a small thermoelectric voltage resulting from a temperature difference. Therefore, the design of the measurement input is an essential component of the entire measurement chain.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.16″ _module_preset=”default” custom_margin=”||||false|false” custom_padding=”||36px|||” global_colors_info=”{}”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}” column_structure=”1_2,1_2″][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” hover_enabled=”0″ global_colors_info=”{}” module_id=”thermo-was-ist” sticky_enabled=”0″]<\/p>\n

A thermocouple is a temperature sensor consisting of two different metallic conductors or alloys that are connected at a junction. When a temperature difference is created between this junction and a reference point, an electrical voltage in the millivolt range is generated. This voltage is measured, and the temperature is calculated from it. This is the basic principle behind all industrial thermocouples. <\/p>\n
Thermocouples are available in many standardized types. The specific combination of materials determines the thermo type<\/strong>, such as type J, K, N, R or T. JEach thermocouple type has its own characteristic curve, a typical range of application, and specific behaviour in terms of sensitivity, temperature range, and long-term stability. MicroControl supports types J, K, N, R, and T in the \u00b5CAN.4.ti-BOX<\/a>; the \u00b5CAN.8.ti-SNAP<\/a> supports types E, J, K, L, N, R and T. <\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” background_color=”#E6E6E6″ custom_margin=”||50px|||” custom_padding=”8px||8px|8px|false|false” hover_enabled=”0″ border_radii=”on|5px|5px|5px|5px” border_width_all=”1px” global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]Inhalt<\/strong><\/p>\n What is a Thermocouple?<\/a> [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||0px|||” custom_padding=”0px||||false|false” global_colors_info=”{}”]<\/p>\n The fundamental physical principle behind a thermocouple is the Seebeck effect<\/strong>. When there is a temperature difference within a conductor, or between two different conductive materials, charge carriers respond to it to different degrees. This generates a measurable electrical voltage. In a thermocouple, this effect is specifically utilized by connecting two different materials at the measurement point. The resulting thermoelectric voltage depends on the temperature difference between the measurement point and the reference point, as well as on the materials used. <\/p>\n It is important to understand that a thermocouple does not directly measure an absolute temperature, but rather a temperature difference. The actual temperature at the measurement point can only be determined if the reference point is clearly defined and measured. This is precisely why cold-junction compensation is an indispensable part of any precise thermocouple measurement. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.16″ _module_preset=”default” use_background_color_gradient=”on” background_color_gradient_stops=”#ffffff 0%|#ececec 100%” background_color_gradient_start=”#ffffff” background_color_gradient_end=”#ececec” custom_padding=”0px||30px||false|false” global_colors_info=”{}”][et_pb_row _builder_version=”4.16″ _module_preset=”default” background_color=”RGBA(0,0,0,0)” custom_margin=”34px|auto|0px|auto|false|false” custom_padding=”7px||0px||false|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” hover_enabled=”0″ global_colors_info=”{}” module_id=”thermo-wie-funktioniert” sticky_enabled=”0″]<\/p>\n [\/et_pb_text][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||25px||false|false” custom_padding=”0px||||false|false” global_colors_info=”{}”]<\/p>\n In practice, the measuring junction of the thermocouple is located at the point where the temperature is to be measured. The other end of the thermocouple is connected to the measurement input. At this point, junctions are formed with other conductor materials, typically copper wires and the input structure of the measurement module. This connection point serves as the reference junction, which is often referred to as the cold-junction<\/strong> in thermocouple technolgy. <\/p>\n The measurement input detects the thermoelectric voltage of the sensor and converts it into a temperature value using the characteristic curve associated with the selected thermocouple type. It should be noted that the thermoelectric voltage of a thermocouple is not in an ideal linear relationship with temperature.<\/strong> The relationship between voltage and temperature depends on the specific thermocouple type and must be kept in mind accordingly during evaluation. <\/p>\n This is why for precise measurement results a simple linear conversion is insufficient. Instead, the temperature value is calculated using stored characteristic curves, polynomials, or lookup tables<\/strong>. In addition, the temperature of the reference point must be considered. Only the combination of voltage measurement, characteristic curve conversion, and cold junction compensation provides the correct temperature value at the measurement point. <\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.27.6″ _module_preset=”default” use_background_color_gradient=”on” background_color_gradient_stops=”#ffffff 0%|#ececec 100%” background_color_gradient_start=”#ffffff” background_color_gradient_end=”#ececec” custom_padding=”20px||25px||false|false” global_colors_info=”{}”][et_pb_row _builder_version=”4.16″ _module_preset=”default” custom_padding=”0px||0px|||” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”|600|||||||” text_text_color=”#ef7c00″ text_font_size=”24px” header_2_font=”|600|||||||” header_2_text_color=”#ef7c00″ header_2_font_size=”24px” custom_margin=”||14px||false|false” hover_enabled=”0″ global_colors_info=”{}” module_id=”thermo-kaltstelle” sticky_enabled=”0″]<\/p>\n [\/et_pb_text][et_pb_text disabled_on=”off|off|off” _builder_version=”4.27.6″ _module_preset=”default” text_font=”|300|||||||” text_text_color=”#565655″ text_font_size=”17px” text_line_height=”1.4em” custom_margin=”||25px||false|false” custom_padding=”0px||||false|false” global_colors_info=”{}”]<\/p>\n Cold-junction compensation is necessary because a thermocouple does not measure absolute temperatures, but only the temperature difference between the measurement point and the reference point. In standard tables and characteristic curves, the thermoelectric voltage is usually referenced to a reference point of 0 \u00b0C<\/strong>. In real-life devices, however, the connection point of the thermocouple is not located in an ice bath of 0 \u00b0C, but typically somewhere on the module or in the control cabinet at a different temperature. This deviation must be compensated for. <\/p>\n Without cold junction compensation, the measurement input would evaluate only the existing temperature difference and thus provide an incorrect absolute temperature value. Cold junction compensation corrects this effect by additionally measuring the temperature at the reference point and including it in the calculation.
