Product Highlights
The LMK458 Level Transmitter is a highly versatile and reliable instrument designed for measuring liquid levels in a wide range of applications. It offers exceptional performance with a nominal pressure range spanning from 0 to 40 cmH2O up to 0 to 200 mH2O. The device provides a 2-wire output signal of 4 to 20 mA, and other output signals are available upon request. One of its outstanding features is its compact size, with a diameter of just 39.5 mm.
Furthermore, the LMK458 holds prestigious certifications, including the LR-certificate from Lloyd’s Register, DNV-approval from Det Norske Veritas, ABS-certificate from the American Bureau of Shipping, and CCS-certificate from the China Classification Society. It demonstrates exceptional resistance to overpressure and offers high long-term stability.
For added flexibility, optional versions are available, such as a diaphragm made of Al2O3 99.9%, different housing materials like stainless steel and CuNiFe, and an IS-version for gas intrinsically safe environments. The transmitter also supports both screw-in and flange versions, and a variety of accessories, including assembling and probe flanges, as well as mounting clamps.
Applications
The LMK 458 Level Transmitter is widely used in water applications, including drinking water abstraction and desalinisation plants. In these environments, the transmitter provides accurate and reliable level measurement, which is essential for monitoring water supply, ensuring quality, and managing resources efficiently. Its robust design and compatibility with potable water make it ideal for both municipal and industrial water management systems, where precise level control is critical for operational safety and regulatory compliance.
In the field of shipbuilding/ offshore, the LMK 458 is particularly suited for use in ballast tanks, where it helps maintain the stability and balance of ships by monitoring and controlling the water levels. Additionally, it plays a vital role in the monitoring of a ship’s position and draught, ensuring safe navigation and compliance with maritime regulations. The transmitter is also used for level measurement in both ballast and storage tanks, providing reliable data in the challenging conditions typical of marine and offshore environments, such as exposure to saltwater, vibration, and temperature fluctuations.
