Endress+Hauser (Endress and Hauser) is a Swiss-based globally operating process and laboratory instrumentation and automation supplier. [2]In 2023, the family-owned business employed over 16,500 people and generated revenue of €3.72 billion. [1]
Diagram of the level instrumentation on a process vessel. The level measurement of liquids in pressure vessels and tanks in the petrochemical industry is undertaken by differential pressure level meters, radar, magnetostrictive, nucleonic, magnetic float and pneumatic bubbler instruments. [1] [9]
As these sensors do not require physical contact with the process material, so the transmitter /receiver can be mounted a safe distance above/from the process, even with an antenna extension of several meters to reduce temperature, yet still respond to the changes in level or distance changes e.g. they are ideal for measurement of molten metal ...
They made a new version of the HT-4, which was known as the BC-610 transmitter, a part of the SCR-299 mobile communications unit, and production began in 1942. General Dwight Eisenhower credited the SCR-299 in the reorganization of U.S. forces, which led to their victory against the Nazis at Kasserine Pass .
Transmitters in the 22 Hz range are also used in pipeline maintenance, or pigging. The signal is generated as an alternating magnetic field, and the transmitter is mounted to, or to part of, the "pig", the cleaning device inserted into the pipe. The pig is pushed through a mostly metal pipeline.
E-field projections on an orthogonal reference frame. Measurements of the EMF are obtained using an E-field sensor or H-field sensor which can be isotropic or mono-axial, active or passive. A mono-axial, omnidirectional probe is a device which senses the Electric (short dipole) or Magnetic field linearly polarized in a given direction.
The E-plane and H-plane are reference planes for linearly polarized waveguides, antennas and other microwave devices. In waveguide systems, as in the electric circuits, it is often desirable to be able to split the circuit power into two or more fractions. In a waveguide system, an element called a junction is used for power division.
In a data-aided approach, the channel estimation is based on some known data, which is known both at the transmitter and at the receiver, such as training sequences or pilot data. [8] In a blind approach, the estimation is based only on the received data, without any known transmitted sequence. The tradeoff is the accuracy versus the overhead.
