Magnetostrictive Level Sensor MLM Series

Overview

The Magnetostrictive Level Sensor MLM Series is engineered to deliver highly accurate and repeatable level measurements across a diverse range of applications. This sensor is ideal for liquid level monitoring in industries such as petroleum, hydraulics, pharmaceuticals, food, and beverages. Designed to withstand harsh industrial environments, the MLM Series ensures reliable performance with minimal maintenance.

Features

Precision and Reliability

• High Accuracy: Ensures highly accurate and repeatable measurements.
• Absolute Output: Provides restart capability without zeroing.
• Multiple Signal Options: Features a fully isolated design to prevent RF interference, capable of measuring multiple position and temperature points simultaneously.

Adjustable and Low Maintenance

• Adjustability: Both zero point and full scale are fully adjustable within the range.
• Maintenance-Free: Designed to operate without the need for regular calibration.

Robust and Flexible Installation

• Installation Flexibility: Easy to install with high dirt resistance and suitability for harsh industrial conditions.
• Structural Integrity: Features a rigid stem structure for excellent pressure-bearing performance, with the option to display with a meter head in the field.

Working Principle

The MLM Series operates on a magnetostrictive principle using a magnetostrictive wire, measuring rod, electronic bin, and a float. This setup precisely detects liquid levels through a torsional wave pulse generated by the sensor’s electronic circuitry, which accurately measures the time difference between pulse current and torsion wave.

Applications

This sensor is versatile for level dosage and control across various sectors:

• Large Storage Tanks: Ideal for large storage tank level measurement with high range capabilities.
• Diverse Industries: Effectively used in petroleum, water conservation, pharmaceutical, food, and beverage industries, as well as in hydrological monitoring and water treatment.
