During the continuous measurement of filling levels, the filling level sensor produces an analog or digital display of the measurement values in different absolute and relative sizes as well as measuring units. For example, some sensors present the value in percentage form. It is also quite common for level sensors to signal the value as a voltage or current.

What kind of level sensors are there and how do they work?<\/h2>\n

Among other things, a differentiation is made between mechanical filling level gauges, electromechanical and hydrostatic measuring systems. In addition, optical systems, conductivity meters and so-called capacitive systems are also used.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”The_filling_level_sensor_with_capacitive_measurement”][vc_column][vc_column_text]\n

The filling level sensor with capacitive measurement<\/h3>\n

Capacitive measurement is suitable both for continuous measurement and for filling level sensors. This technique makes use of the change in electrical capacity between electrodes that are surrounded by a medium. The effect of a change in a medium significantly depends on the so-called dielectric constant. This constant value is used to determine the immersion depth of the electrodes which permits a continuous measurement of the filling level. A special form of this is a switch with frequency swing technology. It can separate foreign matter adhering to the filling level sensor and thus allows for an exact measurement even under difficult measuring surroundings with foam formation and similar influences.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”The_filling_level_sensor_with_optical_measurement”][vc_column][vc_column_text]\n

The filling level sensor with optical measurement<\/h2>\n

The sensor is immersed in the medium and measures the absorption of light or the elimination of the total reflection during the immersion itself. An infrared LED and a light receptor are used. The light directed at a prism on the top of the so-called measuring sensor is first reflected to the receiver. This changes when the tip is immersed in the medium, because its level will rise. The light will refract at the receiver, which is converted into a switching process. The method works best in very pure media, because any pollutions can impact the result.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”Other_technologies_at_the_filling_level_sensors”][vc_column][vc_column_text]\n

Other technologies at the filling level sensors<\/h2>\n

Radar, ultrasound and microwave are also technologically suited for use in filling level sensors. The classic floaters, rotor switches and vibration sensors are the mechanical forms of filling level sensors. They are suitable primarily for limit switches. There are also so-called level probes, differential pressure gauges and filling level sensors that make use of the displacement principle. Even heat conducting and superconducting can be used for filling level measurement.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”Electromechanical_gauging_systems”][vc_column][vc_column_text]\n

In that case, pressures are shown as a water column or in bar units. A filling level limit switch, on the other hand, will output the value via a switch contact. There are combined systems that measure continuously and in the limit switch.

Among other things, a differentiation is made between mechanical filling level gauges, electromechanical and hydrostatic measuring systems. In addition, optical systems, conductivity meters and so-called capacitive systems are also used.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”The_filling_level_sensor_with_capacitive_measurement”][vc_column][vc_column_text] The filling level sensor with capacitive measurement Capacitive measurement is suitable both for continuous measurement and for filling level sensors. This technique makes use of the change in electrical capacity between electrodes that are surrounded by a medium. The effect of a change in a medium significantly depends on the so-called dielectric constant. This constant value is used to determine the immersion depth of the electrodes which permits a continuous measurement of the filling level. A special form of this is a switch with frequency swing technology. It can separate foreign matter adhering to the filling level sensor and thus allows for an exact measurement even under difficult measuring surroundings with foam formation and similar influences.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”The_filling_level_sensor_with_optical_measurement”][vc_column][vc_column_text] The filling level sensor with optical measurement The sensor is immersed in the medium and measures the absorption of light or the elimination of the total reflection during the immersion itself. An infrared LED and a light receptor are used. The light directed at a prism on the top of the so-called measuring sensor is first reflected to the receiver. This changes when the tip is immersed in the medium, because its level will rise. The light will refract at the receiver, which is converted into a switching process. The method works best in very pure media, because any pollutions can impact the result.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”Other_technologies_at_the_filling_level_sensors”][vc_column][vc_column_text] Other technologies at the filling level sensors Radar, ultrasound and microwave are also technologically suited for use in filling level sensors. The classic floaters, rotor switches and vibration sensors are the mechanical forms of filling level sensors. They are suitable primarily for limit switches. There are also so-called level probes, differential pressure gauges and filling level sensors that make use of the displacement principle. Even heat conducting and superconducting can be used for filling level measurement.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row” el_id=”Electromechanical_gauging_systems”][vc_column][vc_column_text] Electromechanical gauging systems A measuring tape with an attached weight is lowered into the medium.

A filling level sensor can be a very precise measuring tool. However, the right kind of sensor needs to be selected, since some measuring technologies are very sensitive to dust or impurities in the measured medium. Some types are very easy to install because they partially even work behind container walls. In general there are so many different technological possibilities for filling level measurement that a suitable solution can be found for every purpose.[\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row”][vc_column][vc_column_text] Other interesting articles [\/vc_column_text][\/vc_column][\/vc_row][vc_row el_class=”no_padding_row”][vc_column width=”1\/3″][vc_column_text] Capacitive sensor Find out everything about the assembly and functionality of a capacitive sensor. \u00bb Capacitive sensor[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_column_text] Capacitive filling level measurement Find out everything about the process and functionality of capacitive filling level measurement. \u00bb Capacitive filling level measurement[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_column_text] Inductive sensor Find out everything about the assembly and functionality of an inductive sensor. \u00bb Inductive sensor[\/vc_column_text][\/vc_column][\/vc_row]","og_url":"https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge\/the-filling-level-sensor","og_site_name":"Rechner Sensors","twitter_card":"summary_large_image","twitter_misc":{"Est. reading time":"6 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge\/the-filling-level-sensor","url":"https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge\/the-filling-level-sensor","name":"The filling level sensor - Rechner Sensors","isPartOf":{"@id":"https:\/\/www.rechner-sensors.com\/en\/#website"},"datePublished":"2019-01-18T11:52:27+00:00","breadcrumb":{"@id":"https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge\/the-filling-level-sensor#breadcrumb"},"inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge\/the-filling-level-sensor"]}]},{"@type":"BreadcrumbList","@id":"https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge\/the-filling-level-sensor#breadcrumb","itemListElement":[{"@type":"ListItem","position":1,"name":"Start","item":"https:\/\/www.rechner-sensors.com\/en"},{"@type":"ListItem","position":2,"name":"Documentation","item":"https:\/\/www.rechner-sensors.com\/en\/documentations"},{"@type":"ListItem","position":3,"name":"Knowledge","item":"https:\/\/www.rechner-sensors.com\/en\/documentations\/knowledge"},{"@type":"ListItem","position":4,"name":"The filling level sensor"}]},{"@type":"WebSite","@id":"https:\/\/www.rechner-sensors.com\/en\/#website","url":"https:\/\/www.rechner-sensors.com\/en\/","name":"Rechner Sensors","description":"[:de]Marktf\u00fchrer in kapazitiver Sensortechnologie und Qualit\u00e4t.[:en]Capacitive Sensors \u2013 for more than 50 years our special field.[:fr]Les capteurs capacitifs \u2013 depuis plus de 50 ans notre c\u0153ur de m\u00e9tier.[:es]Sensores capacitivos - desde m\u00e1s de 50 a\u00f1os nuestro campo de especialidad.[:it]Sensores capacitivos - desde m\u00e1s de 50 a\u00f1os nuestro campo de especialidad.[:]","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/www.rechner-sensors.com\/en\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"}]}},"_links":{"self":[{"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/pages\/52578","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/comments?post=52578"}],"version-history":[{"count":0,"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/pages\/52578\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/pages\/51197"}],"wp:attachment":[{"href":"https:\/\/www.rechner-sensors.com\/en\/wp-json\/wp\/v2\/media?parent=52578"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
