Product Details
1. Introduction
The Eby-ULTRA20 series explosion-proof ultrasonic level gauge is a non-contact level measurement device designed specifically for industrial environments such as flammable, explosive, highly corrosive, and high dust. It integrates ultrasonic measurement technology with strict explosion-proof structural design, and can accurately monitor the level height of various liquids and slurries. It is widely used in high-risk scenarios such as petroleum, chemical, coal mining, medicine, and oil and gas storage and transportation. The equipment strictly follows national explosion-proof standards and international certification requirements, eliminating safety hazards from multiple dimensions such as electrical control, shell protection, and sealing design. It can not only achieve real-time collection, transmission, and monitoring of liquid level data, but also adapt to long-term stable operation under complex working conditions, replacing traditional contact level gauges and solving pain points such as difficult liquid level measurement, low safety, and tedious maintenance in high-risk environments. It provides reliable support for industrial safety production and automation control.

3. Product advantages
3.1 Safe and reliable, with outstanding explosion-proof performance
Strictly designed according to Ex d IIC T6 and Ex ia IIC T6 explosion-proof standards, the shell is made of thickened cast aluminum or 316L stainless steel material, with excellent sealing performance, which can effectively isolate flammable and explosive gases and dust from entering the equipment interior; The internal circuit has undergone current limiting, energy limiting, and short-circuit prevention treatment to eliminate the risk of ignition such as electric sparks and high temperatures. It can be directly applied to Zone 0 and Zone 1 explosive gas environments and has passed multiple international and domestic explosion-proof certifications to ensure operational safety in high-risk scenarios.
3.2 Non contact measurement with wide adaptability
Adopting non-contact measurement method, the probe has no direct contact with the measured medium, and can adapt to various corrosive, crystallization prone, and scaling prone media such as crude oil, acidic and alkaline liquids, sewage, slurry, viscous liquids, etc., avoiding probe wear, blockage, corrosion and other problems, greatly reducing equipment maintenance frequency and cost; The protection level reaches IP68, and it can operate stably for a long time in underwater, humid, and dusty environments.
3.3 Accurate and stable, strong anti-interference ability
Built in intelligent temperature compensation algorithm, which can automatically calibrate the sound velocity deviation under different environmental temperatures, ensuring stable measurement accuracy within a wide temperature range of -40 ℃~80 ℃; It is equipped with false echo filtering technology to effectively overcome steam, foam, dust, tank wall reflection and other interference factors. The measured data is accurate and reliable, with a resolution of 0.1mm, meeting the requirements of high-precision liquid level monitoring.
3.4 Convenient operation, adapted to automated control
Supports both integrated and split installation methods. The split design allows the probe to be installed in high-risk areas and the meter head to be placed in a safe area for easy operation and maintenance; The LCD screen displays real-time information such as liquid level, temperature, and alarms, and is easy to operate and understand; Supporting 4-20mA and RS485 signal output, it can seamlessly connect to industrial automation systems such as PLC and DCS, achieving remote monitoring, data transmission, automatic alarm and closed-loop control, and improving control efficiency.
3.5 Strong durability and long service life
The core components are selected from imported high-quality products, and the probes are made of corrosion-resistant and wear-resistant materials. The housing has undergone anti-corrosion and impact resistant treatment, which can adapt to harsh industrial environments; The equipment has self diagnostic function, which can monitor its own operating status in real time, automatically alarm in case of faults, and facilitate timely troubleshooting and maintenance. Its normal service life can reach more than 5 years.

4.2 Installation Diagram and Requirements
1. Installation position.
2. Installation distance: The minimum distance between the probe and the liquid level shall not be less than 0.3m (blind zone), and the maximum distance shall not exceed the equipment range; The distance between the probe and the tank wall should not be less than 1/10 of the measuring range to avoid interference from reflected waves on the tank wall.
3. Installation method: Using threaded installation (G1.5 standard thread), ensure tight sealing during installation to prevent the infiltration of flammable and explosive gases and liquids; For split type equipment, attention should be paid to the length of the connecting wire between the probe and the meter head (default 5m, can be customized to be extended to 50m), and explosion-proof cables should be used for the connecting wire to avoid areas with strong electromagnetic interference.
4. Environmental requirements: The installation environment should be kept away from strong electromagnetic equipment (such as frequency converters and motors) to avoid electromagnetic interference; Outdoor installation requires sun and rain protection measures, and corresponding customized models should be selected for high and low temperature environments.
(Schematic diagram explanation: The meter head is installed in a safe area and connected to the probe in the high-risk area through an explosion-proof cable; the probe is vertically fixed on the top of the tank to ensure that the measurement direction is unobstructed, and the connecting wire is sealed to comply with explosion-proof regulations.)
