How do Magnetostrictive Sensors Work?

How do Magnetostrictive Sensors Work?

Accurate and reliable measurement is at the heart of modern industrial automation. From monitoring fluid levels in storage tanks to tracking hydraulic cylinder displacement and ensuring safety in oil and gas operations, industries depend on technologies that combine high accuracy, robustness, and long service life. One of the most trusted solutions in this area is the magnetostrictive sensor. Known for its non-contact design and excellent repeatability, magnetostrictive position sensors and magnetostrictive level sensors play vital roles wherever precision measurement is non-negotiable. Understanding Magnetostrictive Sensor A magnetostrictive sensor is a device designed to measure linear displacement, level, or position with remarkable accuracy. The underlying principle is the magnetostrictive effect—the slight change in shape that ferromagnetic materials experience when exposed to a magnetic field. In practical terms, the magnetostrictive position sensor consists of a waveguide, a position magnet, a pickup coil, and electronic circuitry. A short current pulse travels through the waveguide, creating a magnetic field that interacts with the permanent magnetic field of the float or position magnet. This interaction produces a torsional strain wave that moves along the waveguide until it reaches the pickup coil, where it is detected. The time difference between the initial pulse and the arrival of…

Capacitive Level Sensors: Principles & Best Use Cases

Capacitive Level Sensors: Principles & Best Use Cases

Liquid and solid level measurement presents unique challenges across process industries, from managing corrosive chemicals to monitoring sticky food products and detecting powders in storage silos. While many level sensing technologies exist, capacitive level sensors offer a versatile solution that handles difficult materials and challenging conditions where other technologies struggle. Understanding how capacitance level measurement works and identifying the best applications helps engineers and plant managers select the optimal technology for their specific needs. How Capacitive Level Sensors Work: Understanding the Principles Capacitive level sensors operate on the fundamental principle of capacitance—the ability of a system to store electrical charge. In its simplest form, a capacitor consists of two conductive plates separated by a dielectric material (insulator). The capacitance value depends on three factors: the surface area of the plates (A), the distance between them (d), and the dielectric constant (ε) of the material between the plates, expressed in the formula: C = ε × A / d. In a capacitive liquid level sensor, the probe itself acts as one electrode, while the tank wall (for metal tanks) or a reference electrode (for non-conductive tanks) serves as the second electrode. The process material between them acts as the dielectric. As…
