Features of Magnetostrictive Level Transmitters

Magnetostrictive Level Transmitters are divided into three types: flexible probe type, hard probe type, and outer float isolation detection. The watch body contains two main parts: the electronic part and the sensing part. The advantages of Magnetostrictive Level Transmitters are:

  1. Strong reliability:
    Because the magnetostrictive liquid level gauge adopts the principle of waveguide, there is no mechanical movable part. Therefore, there is no friction and no wear. The entire converter is enclosed in a stainless steel tube and is not in contact with the measurement medium. The sensor works reliably and has a long life.
  2. High precision:
    Because the magnetostrictive liquid level gauge works with waveguide pulses. In the work, the measured displacement is determined by measuring the time of the start pulse and the end pulse. Therefore, the measurement accuracy is high and the resolution is better than 0.01%FS. The accuracy achieved.
  3. Good security:
    Magnetostrictive liquid level gauge has high explosion-proof performance. Intrinsically safe explosion-proof and safe to use. Especially suitable for the measurement of chemical raw materials and flammable liquids There is no need to open the tank lid during the measurement. Avoid the unsafeness of manual measurement.
  4. Easy to install and maintain:
    The magnetostrictive liquid level gauge is generally installed through the existing pipe opening on the top of the tank. It is especially suitable for the installation of underground storage tanks and storage tanks that have been put into operation. It can not affect normal production during the installation process.
  5. Facilitate system automation:
    The secondary instrument of the magnetostrictive liquid level gauge adopts the standard output signal. It is convenient for the computer to process the signal. It is easy to realize the network work and improve the automation degree of the entire measurement system.

Sensing part (ie probe rod):

The probe has a diameter of 5/8” and the end is sealed. The inside of the probe is hollow and equipped with precision magnetostrictive wires. In addition to the magnetostrictive wires, the probe can also hold up to 8 RTD The sensor is used to detect the temperature. The maximum length of the probe can be 23 meters, and the flexible cable structure is used above 6 meters.

Electronic part (ie controller):

The shell is made of aluminum alloy or 304 stainless steel. It is a double-chamber type (that is, the transmission part is separated from the wiring part). One of the chambers is a micro-processing module and a circuit board, and the micro-processing module has operation buttons. The other chamber is a binding post. There is a wire connected between the circuit board and the probe processing board. This wire should not be loosened without authorization from the manufacturer.

Magnetostrictive level transmitter price

The price of a magnetostrictive level transmitter is determined based on the measurement conditions. Sino-Instrument is a manufacturer of magnetostrictive level gauges. We offer magnetostrictive level gauges at the right price.

Selection considerations:   

1. The selection of the level gauge should be consistent with the environment of the media on the site. Including ambient temperature, pressure, vibration, shock, compatibility of structural materials and media, etc.   

2. When the temperature of the measured medium is high (100 ~ 200), it is recommended to choose a probe with an outer float type and use a side flange installation. When the temperature is higher (200 ~ 300), it is recommended to choose a probe with a side-bundled type with an outer float, and install it with a side flange.   

3. There are measurement dead zones at the upper and lower ends of the measuring rod of the magnetostrictive level gauge, which should be considered when selecting the range.   

4. The size of the stainless steel magnetic float commonly used for level gauges is Ф45 × 56 × Ф15, and flange connection of DN50 or above is required. For the liquid level gauge with thread connection, users need to install flange or bracket.


What is magnetostrictive transducer?

Magnetostrictive liquid level transmitter is a kind of liquid level sensor. But it uses the principle of magnetostrictive operation internally. And combines modern electronic technology to measure the time value between pulse waves to achieve the purpose of accurately measuring the liquid level . The magnetostrictive liquid level meter works with waveguide pulses. During the work, the measured displacement is determined by measuring the time of the start pulse and the end pulse, so the measurement accuracy is high.

How does a magnetostrictive sensor work?

1.The device electronics generates a low energy current pulse at fixed intervals.
2.The electrical pulses create a magnetic field which travels down a specialized wire inside the sensor tube.
3.The interaction of the magnetic field around the wire and the magnetic float causes a torsional stress wave to be induced in the wire. This torsion propagates along the wire at a known velocity, from the position of the magnetic float and toward both ends of the wire.
4.A patented sensing element placed in the transmitter assembly converts the received mechanical torsion into an electrical return pulse.
5.The microprocessor-based electronics measures the elapsed time between the start and return pulses (Time of Flight). And converts it into a position measure-ment which is proportional to the level of the float.

How does a level transmitter work?

The level of the liquid medium in the container is called the liquid level. And the instrument that measures the liquid level is called the liquid level transmitter. Level transmitter is a kind of level instrument. There are two types of level transmitterss, one is continuous and the other is point-off. The continuous level transmitter is a real-time monitor of the height of the liquid in the container. The point type, which generally takes two points, high and low, and outputs an alarm signal when the medium in the container reaches these two points.The types of liquid level transmitters is very wide. Specific include: magnetic flap liquid level gauge, tuning fork vibration type, differential pressure type, pressure type. Ultrasonic, magnetostrictive liquid level gauge, magnetic flap, radar and so on.
Levels of media such as: water, viscous fluids, and fuels, or dry media such as bulk solids and powders can be measured using the transmitter.
Level measurement transmitter are used in a myriad of applications that require level measurement within containers or tanks. These transmitters often find their application in material handling, food and beverage, power, chemical, and water treatment industries.

What is radar level transmitter?

Radar level transmitter is a kind of liquid level transmitter which uses the principle of radar operation.
Radar Level Sensor also called radar level transmitter, are the indicating transmitter for liquid level.
Non-contact Continuous level measurement in liquids and solids with free space radar sensors.
RADAR (Radio Detection And Ranging) is a device which can detect the presence of faraway objects by obtaining a reflection of electromagnetic waves emitted from the device itself. Although invented much earlier, wide deployment of radar was done by Britain during the Second World War to detect oncoming German bombers.
Radar level measurement is a safe solution. Even under extreme process conditions (pressure, temperature) and vapors. Various antenna versions for every kind of radar applications are available.
In continuous non-contact level measurement with radar, the sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it.
