Restraints:

• Material Limitations Restrict Adoption of Magnetic Level Alarm Switches

A significant restraint in the magnetic level alarm switches market is their incompatibility with non-magnetic materials, such as plastic or certain stainless steels, which are commonly used in modern industrial tanks and pipelines. Since these switches rely on magnetic fields to detect liquid levels, they require materials that allow magnetic flux to pass through effectively. In non-magnetic environments, signal transmission becomes unreliable or entirely ineffective, limiting the functionality of these devices. This constraint is especially critical in industries, such as chemicals or pharmaceuticals, where non-reactive, non-magnetic materials are preferred for corrosion resistance. As a result, industries are often forced to consider alternative level sensing technologies that can operate reliably regardless of tank construction material.

Opportunities:

• Customization Demand Fuels Growth in Magnetic Level Alarm Switches Market

The increasing need for the specific level monitoring and controlling solutions is one of the key factors that are expected to rise the Magnetic Level Alarm Switches market growth over the next few years. Applications, such as chemical, water treatment and manufacturing have an increasing need for dependable, no maintenance sensing technologies to address specific process requirements. That ability to provide fully sealed and dirt-resistant, no-touch versions with SPST or SPDT contacts brings increased safety and reliability, particularly in severe environments. As automation in industry develops and requirements of approval authorities increase, customized solutions with long service lives and high functional reliability are becoming increasingly important. Flexible and high-quality magnetic level switches are offered by companies in strong position to both address these requirements and grow into global or regional markets.

May 2024 – KOBOLD USA has launched a new generation of its M-series magnetic level switches that offer customizable float switch designs with hermetically-sealed, SPST and SPDT contacts to satisfy many liquid level applications.

Challenges:

• Industrial Electromagnetic Noise Undermines Magnetic Switch Accuracy

Magnetic level alarm switches have been seriously hampered in performance by the existence of strong external magnetic fields or EMI in industrial fields. These switches use magnetic field sensing to provide accurate liquid-level monitoring, but vibrations from nearby motors, high-power equipment, or radio frequency equipment can impact the magnetic fields. Such disturbances may cause false indication in terms of level, delayed response and signal loss, jeopardizing the safety and reliability of a process. With many industries becoming more automated and using high-power electrical equipment, the exposure of magnetic switches to EMI requires new methods of advancing military and industrial sensing, including shielding, isolation, or new sensing technologies to ensure accurate performance in high-noise environments.
