Overview said

    LMTECH magnetostrictive liquid level gauge is an innovation with integrated intelligence, high precision and high reliability

Technical product, its birth has solved the measurement of liquid level and boundary level under extremely harsh working conditions. Its products

The principle determines that the measurement process is not affected by changes in temperature, pressure, dielectric constant and other factors,

Set the advantages of high precision, high stability, high anti-interference ability, maintenance-free, etc., make up for the electric float level

And other liquid level measurement products such as pressure gauges, differential pressure transmitters, radars, etc.

foot. It is widely used in liquid level and interface measurement in electric power, petrochemical and other industries.

Product technical features

● Accuracy up to 0.01% FS (Full Scale), repeatability reaches 0.005% FS

● Can simultaneously output two 4 ~ 20mA analog quantities, used to detect liquid level, boundary or temperature, and can measure up to 5 temperature points at the same time

● With Hart Communication Association, PROFIBUS PA bus, MODBUS (RS-485) bus

● Electronic modules can be exchanged on site for easy testing and maintenance

● Maintenance free, no need for secondary calibration

● The zero point and full scale position can be set arbitrarily on site

● Split reading and on-site indication are optional

● Optional remote transmitter

● No need to recalibrate, set once, permanent memory; the only movable part is float, maintenance amount

    Very low and extremely stable.

working principle

    After energization, the electronic component sends out a current interrogation pulse.

At the same time, a magnetic field is generated to move down the waveguide, when the magnetic field generated by the current pulse

When intersecting the fixed magnetic field of the magnetic float, a torsional stress wave, or return pulse for short, is generated

Impulse, because the propagation speed of the return pulse in the waveguide is fixed, so through accurate

Measure the time interval between the interrogation pulse and the return pulse to obtain high precision,

Highly repeatable level values.
