1. Working Principle of a Torque Sensor A torque sensor, also known as a torque transducer, is a device that converts the mechanical torque applied to it into a measurable electrical signal. The most common type is the strain gauge torque sensor, which operates based on the Wheatstone bridge principle. In this design, strain gauges […]

Introduction Sensor drift refers to the phenomenon where a sensor’s output deviates from the true value over time, even when the input remains constant. It poses a major challenge in industrial measurement and control applications, particularly for pressure, displacement, and temperature sensors. If left uncorrected, sensor drift can degrade system accuracy, lead to false alarms,

Environmental protection and monitoring have become critical priorities in the modern era. Advanced instruments play a vital role in ensuring accurate and reliable data collection for better decision-making and sustainable management. This article explores how instruments are utilized in monitoring two key environmental areas: water and soil. Water Environment Monitoring Water is the source of

For any company, ensuring the safety of its employees and maintaining a safe production environment are of utmost importance. Many factories are continually striving to minimize the time workers spend in hazardous areas, and one of the most effective measures to achieve this goal is the use of automated instrumentation and control equipment. These instruments

Sensor technology has made significant advancements since its inception in the early 20th century. Initially, basic mechanical and electrical sensors were primarily used for industrial applications, laying the foundation for future developments. These early sensors were relatively simple, relying on mechanical components to measure variables such as pressure, temperature, and motion. Mid-20th Century: The Introduction

Introduction When conducting a specific measurement task, the first step is to determine the most suitable type of sensor. This decision requires a comprehensive analysis of multiple factors, as even for measuring the same physical quantity, there may be several sensor types available. The selection should be based on the characteristics of the measured object

A sensor (or transducer) is a device that detects and responds to a physical stimulus such as light, heat, sound, pressure, or motion. It converts this detected stimulus into an electrical signal or another form of information, following a defined pattern. This conversion process allows for the transmission, processing, storage, display, recording, and control of

With the advancement of industrial automation, the role of sensors in measurement, control technology, and instrumentation has become increasingly critical. The statement, “Without sensor technology, there would be no modern science and technology,” has gained universal recognition. Sensors serve as the bridge between physical reality and digital processing, converting environmental data into electrical or optical

1. Proximity Sensing Proximity sensing primarily involves detecting: The presence or absence of an object. The size or simple shape of an object. Proximity sensors can be categorized into contact or non-contact types and can operate in analog or digital modes. The selection of sensors depends on physical, environmental, and control conditions. Common types include:

Modern sensors vary greatly in terms of their principles and structures. The challenge lies in selecting the most appropriate sensor based on the specific measurement objectives, measurement targets, and environmental conditions. Choosing the right sensor is the first problem that needs to be solved when measuring a particular quantity. Once the sensor is selected, the
