Why Choose Feejoy's Magnetostrictive Level Transmitter?

Feejoy Technology's magnetostrictive liquid level gauge can measure the oil tank's liquid level and temperature, and can also measure the oil tank's leakage. The leak detection accuracy reaches 0.375 liters/hour, which can meet the needs of different users, to achieve a higher price-performance ratio.

What parts is magnetostrictive liquid level gauge composed of?

Detection rod, circuit unit and float. During the measurement, the circuit unit generates a current pulse, which is transmitted down the magnetostrictive line and generates a ring-shaped magnetic field.

What advantages does magnetostrictive level transmitter have when measuring the oil tank liquid level?

Strong reliability: Since the magnetostrictive liquid level gauge adopts the principle of the waveguide, there is no mechanical movable part, so 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. High precision: Because the magnetostrictive liquid level gauge works with waveguide pulses, the measured displacement is determined by measuring the time of the start pulse and the end pulse during the work, so the measurement accuracy is high, and the resolution is better than 0.01% FS, which Accuracy that is difficult to achieve with other sensors. Good safety: The magnetostrictive liquid level gauge has high explosion-proof performance, intrinsically safe explosion-proof, and is safe to use, especially suitable for the measurement of chemical raw materials and flammable liquids. It is not necessary to open the tank lid during measurement to avoid the unsafeness of manual measurement. The magnetostrictive liquid level gauge is easy to install and maintain: the magnetostrictive liquid level gauge is generally installed through the existing nozzle on the top of the tank and is particularly suitable for the installation of underground storage tanks and operational storage tanks. The process does not affect normal production. Facilitate system automation work: The secondary instrument of the magnetostrictive liquid level gauge adopts standard output signals, which is convenient for the computer to process the signal, and it is easy to realize networked work and improve the automation degree of the entire measurement system.

RF Type Admittance Level Switch/Sensor Manufacturer-Feejoy

The RF admittance level switch is the RF admittance level meter, and the potentiometer W1 of the radio frequency admittance level meter is a sensitivity adjustment potentiometer: the LED two-color display lamp lights in green when there is no material, and the red light when there is one. After the meter is powered on, the green light is on when the level is lower than the set value.

At this time, slowly adjust the potentiometer W1 clockwise until the red light is on, and then adjust it 3 times counterclockwise (0.5 to 3 times for non-conductive materials, conductive material 5 ~ 7 circles) and the green light is on (the status of the output relay's contacts should change with the change of the traffic light display state). According to the measurement part of different RF admittance level transmitters, it should be covered by materials at about 75mm.

RF Admittance Level Switch FAQs

What is RF admittance level switch?

RF admittance level switch compared to capacitance level switch adopts more advanced RF admittance technology instead of capacitance measurement, which solves the problem of material adhesion.

Why choose RF admittance level switch?
