Application of Magnetostrictive Displacement Sensors in Water Treatment Systems

In water treatment scenarios such as urban water supply and industrial wastewater treatment, the accurate monitoring of liquid level and displacement is crucial for ensuring process stability, effluent compliance, and equipment safety. Magnetostrictive displacement sensors, with their exceptional environmental adaptability and reliability, have become an indispensable "sensing tool" in water treatment systems, providing stable monitoring support for various treatment stages.

Core facilities in water treatment systems, such as sedimentation tanks and filter beds, demand extremely high precision in liquid level control. An excessively high level can cause overflow and waste, while a level that is too low can adversely affect sedimentation and filtration efficiency, ultimately impacting effluent quality. Magnetostrictive displacement sensors utilize a non-contact measurement method, enabling precise detection of level changes without direct contact with the water medium. Compared to traditional contact sensors, which are prone to failure due to corrosion and scaling, these sensors maintain stable long-term monitoring. This ensures that critical operations like sludge discharge in sedimentation tanks and backwashing in filter beds are performed under appropriate level conditions, guaranteeing the efficient operation of core water treatment processes.

Water treatment environments are often humid and corrosive, with some areas facing challenges like high-pressure washing and chemical erosion, placing stringent demands on equipment protection. Magnetostrictive displacement sensors boast a protection rating of IP68/IP69K, and feature stainless steel electronics housings and measuring rods. This effectively resists damage from water immersion, chemical corrosion, and high-pressure washdowns. Even in complex environments such as damp pump houses or outdoor storage tanks, they continue to operate stably, preventing monitoring interruptions due to equipment failure and ensuring the continuous operation of the water treatment system.

Water treatment systems often require 24/7 uninterrupted operation, demanding high reliability and ease of maintenance from their components. Magnetostrictive displacement sensors support absolute value output. Even in the event of a temporary power outage, they resume monitoring immediately after power restoration without the need for recalibration, avoiding impact on system operation due to data loss. Furthermore, their wide operating temperature range adapts to temperature variations in different regions, eliminating the need for additional temperature control equipment and significantly reducing maintenance costs and complexity. This helps water treatment systems achieve long-term, stable, low-failure operation goals, providing solid technical support for water purification and recycling.
