摘要： A system provides a level detector with a multi-axis magnetometer sensor that senses movement of a magnet connected to a float within a vessel. A temperature sensor may assist in compensating for changes to the magnetic field due to ambient temperature. Output from the sensor is provided to a local data processing unit which provides level data to a local display. The local data processing unit sends data through a communications port to a remote system which can track level remotely as well as assimilate and uniquely characterize data from other vessels to provide more accurate level measurement by the local processing unit.

摘要： A liquid level detection device includes a float that ascends and descends following a liquid level, a magnet attached to the float, a guide that guides the float to ascend and descend, magnetic sensors attached to the guide and sensing a magnetic flux density varying in response to a position assumed by the magnet as the magnet ascends/descends and outputting an electrical signal corresponding to the magnetic flux density, and a detection circuit that detects a position of the float based on electrical signals respectively output from the magnetic sensors. The detection circuit detects the position of the float based on electrical signals output from two adjacent ones of the magnetic sensors.

摘要： A float floats on a liquid inside a container and is movable upward and downward according to a liquid surface level. A cover is located inside the container and houses the float inside the cover. A detector detects the position of the float. The cover includes a support part and a wall part. The support part allows upward and downward displacement of the float and restricts displacement of the float outward from the cover. The wall part is located around the support part. The wall part has an opening that allows communication between the inside of the cover and the outside of the cover. The area of the opening is larger than the surface area of the wall part except the opening.

摘要： A liquid level detector includes a casing having a first regulatory section and a second regulatory section, a float that has its upward and downward displacement restricted by contact with the first regulatory section or the second regulatory section, a magnet body that is held by the float, and a switch mechanism that is switched between an on-state and an off-state. A first distance from a switching plane to the first regulatory section and a second distance from the switching plane to the second regulatory section are both longer than a length from one magnet end face to a bottom end section.

摘要： A liquid surface sensor includes a case fastened to a washer tank, and a float assembled to the case and is movable relative to the case in a vertical direction. The float supports a magnet. The case is provided with a reed switch axle receiving a reed switch that is switched to an off state to an on state when being approached by the magnet. The reed switch axle supports the float to move up and down. The reed switch includes a switch main body, and a conductive film covering an outer surface of the switch main body and extending from a reed is arranged on the switch main body. The conductive film transmits a signal that indicates an on state of a switch or an off state of the switch and is transmitted to the reed.
