Basics of Magnetostrictive Level Transmitters
There are many different types of magnetostrictive level transmitters. Each of these devices is designed to measure a specific level or position. They work by sending an electrical current up a magnetically-torqued wire. The magnetic field generates a pulse or mechanical twist, which travels back down the wire at the speed of sound. This device measures the time difference between the return pulse and the initial pulse.
A magnetostrictive level transmitter is a continuous float level sensor that creates competing magnetic fields, which generate an output signal corresponding to the liquid level. Besides magnetostrictive level transmitters, other types of continuous level sensors include radar transmitters, ultrasonic sensors, and submersible pressure transducers. The basic premise of these devices is based on the idea that ferromagnetic substances or molecules respond to a magnetic field and convert it into mechanical energy.
When used in a process where the liquid levels change with different conditions, magnetostrictive level transmitter are an excellent choice. A float is attached to a wire with a ferromagnetic magnet. This metal aligns itself with the magnetic field at the molecular level and produces a signal denoting the liquid’s level. When a float is at the right level, the signal generated by the sensor will vary accordingly.
Despite their relatively simple design, magnetostrictive level transmitters are often the most complex to use. The float acts as a sensor, and the electronics send a current pulse through the wire. This magnetic pulse interacts with a magnetic field in the float, which then creates a signal corresponding to the level of the liquid. When the float reaches a certain level, a magnetic wave will occur along the wire.
The Basics of Magnetostrictive Level Transmitters
Unlike other types of transmitters, magnetostrictive level transmitters are designed to be very accurate. The accuracy of this type of sensor is one millimeter. The sensor circuitry is integrated into the float. A float is a float that is magnetized in both axial and radial directions. The resulting signal is a signal that corresponds to the level of the liquid.
The Basics of Magnetostrictive Level Txs are a popular type of level transmitters. They are highly accurate and can report the filling level to within 0.04 inches. They also have low installation and calibration costs and a long lifespan. The benefits of magnetostrictive transmitters far outweigh the disadvantages of other type of transmitters. You should understand the basic principles and benefits of these level transducers before choosing one for your facility.
The LTM Magnetostrictive Level Transmitters are very versatile. They are designed to measure the level of liquids. The sensor is an alloy wire wave guide that is mounted on the outside of the bypass level indicator. The transmitter then sends a microwave pulse to the liquid’s surface, allowing it to calculate the exact amount of liquid. The pulse reflects the level in the form of an output signal, which is a 4/20mA.
