Fluctuations up to 100 kHz or more can be measured.<\/li>\n<li>High dynamic range. Velocities from a few cm\/s up to several hundred m\/s can be measured with almost constant sensitivity.<\/li>\n<li>Little disturbance of the flow, due to small sensor sizes.<\/li>\n<li>High spatial resolution. Eddies down to some tenths of a mm can be resolved.<\/li>\n<li>Continuous signal.<\/li>\n<\/ul>\n<p>The basic working principle makes it possible to determine fluctuations in any parameter that, in addition to the velocity, influences the heat transfer from the sensor -i. e. density, pressure, temperature and composition- provided proper means are taken.[\/vc_column_text][vc_column_text]<strong>Probe construction<\/strong><\/p>\n<p>In general, a probe consists of the following:<\/p>\n<ul>\n<li>Sensor, forming the heating element.<\/li>\n<li>Sensor supports, carrying the sensor and leading current to it.<\/li>\n<li>Probe body, carrying the sensor supports.<\/li>\n<li>Connector, providing electrical connection to the probe support or probe cable.<\/li>\n<\/ul>\n<p>Probes may have one, two or three sensors for use in one-, two- or three-dimensional flows, respectively. Each sensor requires its own anemometer bridge.<br \/>\nThe sensor may either be a thin wire suspended between two prongs or a thin metal film deposited on an electrically insulating substrate. Film sensors can be cylindrical (fiber-film probes) or non-cylindrical (film probes). Wire sensors are used in gases and in non-conducting liquids, where as film sensors are primarily designed for use in water and other conducting liquids.<br \/>\nThe sensor materials are selected to provide maximum flow sensitivity and highest possible mechanical strength with a minimum of thermal inertia. The size of the sensor and its mounting are selected to give minimal disturbance of the flow.[\/vc_column_text][vc_column_text]<strong>Probe body design<\/strong><\/p>\n<p>The probe bodies are designed to provide a rigid, aerodynamic mounting of the sensors and sensor supports with a reliable electrical contact further on to the probe support or to the probe cable.[\/vc_column_text][vc_column_text]<strong>Probe supports<\/strong><\/p>\n<p>All plug-in probes are mounted using probe supports. They serve as the electrical connection between probe and probe cable and provide a mechanical mount for the probe at the same time.[\/vc_column_text][vc_column_text]<strong>Manufacturer&#8217;s responsibility<\/strong><\/p>\n<p>Dantec Dynamics is responsible for the safety, reliability and performance of the items described in this catalog only if:<\/p>\n<ul>\n<li>The specific environmental conditions correspond to the requirements stated for the specific item in this catalog or on the probe or probe support container.<\/li>\n<li>Persons authorized by Dantec Dynamics carry out modifications or repairs.<\/li>\n<li>The items are used in accordance with the recommendations given herein or on the probe or probe support container.<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column width=&#8221;1\/2&#8243; css=&#8221;.vc_custom_1484828983369{margin-bottom: 25px !important;}&#8221;][vc_column_text]Dantec Dynamics offers a complete probe system for use with Constant Temperature Anemometers (CTA).
