Tank Level Sensor APG Magneto Resistive: A Comprehensive Guide

Introduction

Accurate tank level measurement is crucial in various industries, including oil and gas, chemical processing, and manufacturing. One reliable and precise technology used for tank level sensing is the tank level sensor APG magneto resistive. This article delves into the world of tank level sensor APG magneto resistive, exploring its operation, benefits, applications, and more.

What is a Tank Level Sensor APG Magneto Resistive?

A tank level sensor APG magneto resistive is a device that measures the level of liquid in a tank using the principle of magnetorestriction. It consists of a float that moves along a guide wire or rod suspended inside the tank. The float contains a magneto resistive element that changes its electrical resistance in response to changes in the magnetic field.

How Does a Tank Level Sensor APG Magneto Resistive Work?

The magneto resistive element in the float is positioned within a magnetic field generated by a permanent magnet or electromagnet. As the float moves up or down with the liquid level, the distance between the element and the magnet changes. This variation in distance alters the magnetic field strength, which in turn affects the electrical resistance of the magneto resistive element.

The change in electrical resistance is detected and converted into a signal that is proportional to the liquid level. The signal is then transmitted to a remote display or control system for monitoring and data analysis.

Benefits of Tank Level Sensor APG Magneto Resistive

• High Accuracy and Precision: Magneto resistive sensors offer precise and reliable level measurement with an accuracy of up to ±0.25%.
• Wide Temperature Range: They can operate in extreme temperature conditions, typically ranging from -40°C to 125°C (-40°F to 257°F), making them suitable for various industrial applications.
• No Moving Parts: Magneto resistive sensors have no moving parts, eliminating the risk of mechanical wear and tear. This enhances durability and reduces maintenance requirements.
• Corrosion Resistance: The sensors are constructed using corrosion-resistant materials, enabling them to withstand harsh environments, such as chemical tanks.
• Intrinsically Safe: Magneto resistive sensors are intrinsically safe, meaning they can be used in potentially explosive or flammable atmospheres.
