The EAX4 ultrasonic level transmitter is an advanced non-contact level measurement solution designed for industrial tank monitoring and process control applications. Using high-frequency ultrasonic wave technology, the device accurately measures liquid levels by calculating the time taken for sound waves to reflect from the surface of the material. This non-contact measuring principle ensures reliable performance even in challenging environments where traditional sensors may fail.
Ideal for water treatment plants, chemical processing facilities, storage tanks, and industrial manufacturing systems, the transmitter delivers consistent level monitoring while reducing maintenance requirements. With integrated signal processing, echo filtering, and temperature compensation, the EAX4 provides stable and accurate measurement across a wide range of industrial liquid applications.
Key Features
The transmitter is engineered to provide dependable performance in demanding industrial environments. Its non-contact ultrasonic sensing eliminates direct contact with liquids, preventing corrosion and sensor wear. The integrated electronics provide precise signal conversion and stable analog output for seamless system integration.
Key advantages include:
- Non-contact ultrasonic level measurement
- Reliable 4–20 mA analog output for industrial control systems
- Integrated temperature compensation for improved accuracy
- False echo detection technology for stable measurement
- Durable housing with high environmental protection
- Maintenance-free operation with no moving parts
These features make it a preferred solution for continuous level monitoring in tanks, reservoirs, and process vessels.
Design & Functionality
The EAX4 transmitter operates by emitting ultrasonic pulses toward the liquid surface. Once the signal reflects back to the sensor, the system calculates the distance based on the transmission time of the sound wave. This measurement is then converted into an analog output signal used by PLC, SCADA, or other industrial control systems.
The compact integrated design allows easy installation on tank tops or process vessels. The PVDF probe material ensures durability and chemical resistance, while the rugged housing protects internal components in industrial environments.
Total Crossed Beams
The transmitter utilizes a focused ultrasonic beam that maintains consistent signal strength and measurement stability. The optimized beam structure minimizes interference from tank walls, internal structures, and liquid turbulence, ensuring accurate level detection.
Beam Pitch Options
The device provides a narrow beam angle that improves measurement precision in narrow tanks, storage vessels, and industrial containers. This focused transmission allows reliable operation even in confined or obstructed installations.
Intrinsic Synchronism
Integrated signal processing ensures synchronized ultrasonic pulse transmission and echo reception. This synchronization enhances measurement stability while reducing signal noise caused by environmental factors such as vapor, temperature changes, or surface agitation.
Operational Advantages
Industrial facilities benefit from the transmitter’s low maintenance design and long operational life. Because the sensor does not contact the measured liquid, it avoids contamination and mechanical wear. The system provides reliable real-time level monitoring for process control, inventory management, and safety applications.
The transmitter is widely used in industries such as water and wastewater treatment, chemical storage, petrochemical plants, food processing, and industrial manufacturing facilities where accurate liquid level monitoring is essential for operational efficiency.
