3、 Core advantages of the product
1. Micron level measurement accuracy, zero data drift
Eby-YC300 adopts imported high-precision nickel iron alloy waveguide wire, combined with a 32-bit high-speed processor, to achieve * * ± 0.1mmUltra high precision measurement, with a resolution of up to0.01mm**。 Based on the principle of physical time difference measurement,No mechanical wear, no signal attenuation, no need for regular calibrationWorking continuously for 5 years, the accuracy drift is ≤ 0.05% FS, solving the problem of long-term accuracy decline in traditional level gauges and meeting the requirements of high-precision process control.
2. Strong anti-interference ability, suitable for complex working conditions
adoptFully shielded electronic compartment+twisted pair shielded cableDesign to effectively resist interference from on-site frequency converters, motors, and strong electromagnetic radiation. The 304 stainless steel rigid measuring rod has a stable structure and is not affected by the medium foam, dust and steam. Even though the medium is slightly fluctuating and viscous, the measurement data is still stable without fluctuation. Specially optimized for micro pressure conditions of 0.007-0.12MPa, pressure changes do not affect measurement results and are suitable for complex and variable industrial sites.
3. Two wire design, minimal installation and debugging
24VDC two-wire circuit power supply+4-20mA outputOnly two cables are needed to complete power supply and signal transmission, greatly saving wiring costs, and compatible with all industrial control systems such as DCS, PLC, display instruments, etc. Top mounted with DN50 PN2.5 standard flange, the equipment only needs to be vertically fixed to the top of the container during installation. The flange seal is reliable and there is no risk of leakage. No need for complex calibration, it can work immediately after power on, supports quick calibration with on-site buttons, and can be installed and debugged by a single person in 10 minutes.
4. On site display+remote monitoring, easy to operate
integrationLCD on-site displayReal time liquid level, percentage, current signal, and fault code can be viewed intuitively without the need for external equipment, making it convenient for on-site inspection and debugging. The 4-20mA standard analog signal can be transmitted over long distances (≤ 1000m), enabling remote real-time monitoring of liquid level data and seamless integration into factory automation control systems, meeting the dual requirements of "on-site monitoring+remote control".
5. Made of 304 stainless steel material, it has a long corrosion resistance life
The fully connected components are made of high-quality 304 stainless steelIt is resistant to corrosion from most media such as water, weak acid, weak alkali, and oil. It has high mechanical strength, is not easily deformed, and has a service life of over 10 years. The float adopts high-density permanent magnets, which have no magnetic attenuation in a high temperature environment of 50 ℃, and will not jam or lag during long-term use. The whole machine has IP67 protection and ExiaICT6 explosion-proof, and can operate stably in humid, dusty, flammable and explosive hazardous areas.
6. Zero maintenance design, reducing operation and maintenance costs
productNo mechanical movable partsThere are no issues of wear, jamming, or aging, and daily maintenance is not required. The surface of the measuring rod is smooth and not prone to scaling. If the medium adheres, it can be easily wiped clean. The electronic components adopt industrial grade high reliability devices, with MTBF (average time) ≥ 50000 hours, significantly reducing maintenance costs and downtime risks in the later stage.
4、 Working principle
The Eby-YC300 series magnetostrictive liquid level gauge is based onMagnetostriction effect (Wiedemann effect)work
Pulse emissionThe controller inside the electronic chamber generates microsecond level current pulses that propagate along the nickel iron alloy waveguide wire inside the measuring rod, forming an instantaneous annular magnetic field.
Magnetic field couplingThe float, which rises and falls with the liquid level, has a built-in magnet that generates a static axial magnetic field; Two magnetic fields intersect and superimpose at the position of the float.
Twisted wave generationThe superposition of magnetic fields triggers the magnetostriction effect, and the waveguide wire generates tiny mechanical torsional waves (ultrasonic waves) at the intersection.
Signal feedbackTwisted waves propagate back to the electron chamber along the waveguide at a fixed speed of approximately 2800 m/s.
Liquid level calculationThe electronic unit accurately measures the time difference Δ t between pulse emission and echo reception, using the formulaLiquid level=v × Δ t/2(v is the wave velocity) Calculate the float position, which is the actual liquid level height, and finally convert it into a 4-20mA signal output and display it synchronously.

6、 Installation and maintenance
（1） Installation requirements
Vertical top installation, flange installation surface horizontal, measuring rod vertical deviation ≤± 1 °.
The measuring rod should avoid the feeding port, mixer, and internal components of the tank, and be at least 50mm away from the tank wall.
The float has no obstacles in its active range, ensuring free rise and fall with the liquid level.
The sealing gasket is made of temperature resistant and medium resistant materials (PTFE gasket, nitrile rubber gasket) to ensure a leak free seal.
（2） Debugging method
Wiring: Strictly distinguish the positive and negative poles of the power supply, connect the 24VDC to a two-wire terminal to avoid reverse connection.
Calibration: After power on, set the range (0-600mm) and unit through the on-site display button, and perform zero point (4mA) and full range (20mA) calibration.
Test: Manually lift and lower the float, check if the displayed value corresponds linearly with the output current, and confirm that the measurement is normal.
（3） Maintenance and upkeep
Regularly check whether the flange seal and cable connection are intact, without looseness or leakage.
When cleaning the attachments on the surface of the measuring rod, gently wipe it to avoid scratching or bending the measuring rod.
No regular calibration is required. If there are any abnormal data, first check if the float is stuck or if the measuring rod is deformed.
