Guide to Flow Measurement Devices: Types and Selection

Explore flow measurement devices. Compare DP, magnetic, and other flow meters to select the right industrial sensor for your application. Flow measurement devices are used to measure the flow rate of fluids in pipes or open channels. Common types include electromagnetic flow meters, ultrasonic flow meters, and turbine flow meters. In my experience working with industrial systems, accurate data is the backbone of efficiency. Before diving into specific hardware, we have to understand the physics that dictate how fluid flow measurement devices actually work. It isn’t just about sticking a sensor......

Strain Gauge Torque Sensors & Transducers – Technology and Selection Guide

By exploring the types and principles of strain gauge torque sensors, analyzing selection guides and calibration-related issues, we hope to help you choose the high-precision rotary and reaction torque measurement solutions that meet your needs. How Strain Gauge Torque Sensors Work? The core principle of the Strain gauge torque sensor is simple: we are converting mechanical shear stress (the twist) into a change in electrical resistance. When a metal shaft is under torque, it deforms slightly—imperceptibly to the human eye, but easily detected by our sensors. We bond a tiny strain gauge to the......

What Is Cold Junction Compensation in Thermocouples? And the 5 Methods

What is Cold Junction Compensation in Thermocouples? Cold junction compensation is a corrective measure taken in thermocouple measurements to eliminate measurement errors caused by the cold junction temperature deviating from 0°C. The need for cold junction compensation in thermocouples stems from their working principle. Let’s analyze this in detail.
