DTM magnetostrictive transmitter includes sensors and transmission part. Sensors are made of stainless steel guide rod, waveguide line (waveguide line—a material has scalability features under the role of the intersecting magnetic field), mobile magnetic ring (containing permanent magnet) and electronic storage and other components composition. Sensor part transforms the physical signal into corresponding electrical signal. And then the transmission part transforms the electrical signal into standard analog signal and export. DTM magnetostrictive design is based on some metals (such as nickel-iron alloy) have the characteristics of magnetostriction under the role of the intersecting magnetic field, which is called Veidemann effect. When measuring, the sensor detector sends a start pulse on one terminal of the magnetostrictive waveguide line, which will form a magnetic field perpendicular to the transmission line(see photos below), and the magnetic field transmits following the pulse current along the transmission line at the speed of light. Once the magnetic field come across the magnetic field produced by the magnetic ring which is set outside the waveguide line, the intersect magnetic field is formed. The waveguide line produces the transient tension under the role of the intersecting magnetic field, which will make the waveguide line twisting and producing the twist wave, this twist wave (the velocity is about the speed of sound) is running along the waveguide, and when it returns to the detector, it produces the inverse magnetostriction phenomenon, and forms a return electrical pulse on the sensor probe. The time difference between the transmitting initial pulse and the receiving return pulse is related to the magnetic ring position, the transmitter transforms the time difference signal (displacement of the magnetic ring) into the standard current or voltage signal and export.
DTM11 magnetostrictive displacement transmitter uses magnetostrictive measurement, the high frequency counter accepts the pulse signal which can up to one ten thousandth of the measurement accuracy. DTM11 magnetostrictive displacement transmitter is compact, easy installation, stable and reliable, the measuring part uses non-contact type, so it can have a long life.
The electronic cabin of DTM11 can be divided into B type and C type. The B type is suitable for some adverse circumstances: greasy dirty and water drenching. B type is suitable for the narrow installation space.
