The minimum measurement uncertainty requires the calibration of at least 4 original measuring blocks from the same set, each with a nominal length of more than 3 mm and a total length of maximum 100 mm.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Mechanical calibration<\/strong><\/p>\n<p>Mechanical calibration is performed by comparison with an equivalent guage block calibrated interferometrically. Mechanical calibration is faster than interferometric calibration and does not require the same high standards of the guage blocks. The measurement uncertainty is typically a factor of two larger. It is possible to have a five-point calibration carried out as per. ISO3650, allowing the flatness of the surfaces to be estimated. For mechanical calibration with comparator, DFM has gauge blocks in steel and carbide in most common metric lengths.<\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.14.4&#8243; _module_preset=&#8221;default&#8221; header_font=&#8221;|300|||||||&#8221; header_2_font=&#8221;|300|||||||&#8221; custom_margin=&#8221;50px||||false|false&#8221; custom_padding=&#8221;||||false|false&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h2><strong>Calibration of distance sensors and actuators<\/strong><\/h2>\n<p>[\/et_pb_text][et_pb_text ul_type=&#8221;square&#8221; ul_position=&#8221;inside&#8221; _builder_version=&#8221;4.14.4&#8243; text_font_size=&#8221;15px&#8221; header_text_color=&#8221;#ffffff&#8221; custom_margin=&#8221;||||false|false&#8221; custom_margin_tablet=&#8221;50px||70px||false|false&#8221; custom_margin_phone=&#8221;&#8221; custom_margin_last_edited=&#8221;on|phone&#8221; custom_padding=&#8221;||||false|false&#8221; custom_padding_tablet=&#8221;|10%||10%|false|true&#8221; custom_padding_phone=&#8221;|10%||10%|false|true&#8221; custom_padding_last_edited=&#8221;on|tablet&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p>DFM can calibrate many different types of distance sensors and actuators used to measure or perform linear displacements.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][et_pb_column type=&#8221;1_4&#8243; _builder_version=&#8221;4.14.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][et_pb_text _builder_version=&#8221;4.14.4&#8243; _module_preset=&#8221;default&#8221; header_font=&#8221;|300|||||||&#8221; header_2_font=&#8221;||||||||&#8221; custom_margin=&#8221;-5px||||false|false&#8221; custom_padding=&#8221;0px||||false|false&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h3>Contact person<\/h3>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/dfm.dk\/wp-content\/uploads\/2020\/08\/DFM_S\u00f8ren_kynde-1024&#215;640.jpg&#8221; title_text=&#8221;DFM_S\u00f8ren_kynde&#8221; show_bottom_space=&#8221;off&#8221; align=&#8221;center&#8221; _builder_version=&#8221;4.14.4&#8243; _module_preset=&#8221;default&#8221; width=&#8221;100%&#8221; custom_margin=&#8221;-10px||||false|false&#8221; custom_padding=&#8221;||||false|false&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.14.4&#8243; _module_preset=&#8221;default&#8221; background_color=&#8221;#f2f2f2&#8243; width=&#8221;100%&#8221; module_alignment=&#8221;center&#8221; custom_margin=&#8221;||||false|false&#8221; custom_padding=&#8221;5%|5%|5%|5%|true|true&#8221; hover_enabled=&#8221;0&#8243; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<h5><b>S\u00f8ren A.
