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.

Orifice Plate Tapping Guide

An orifice plate flow meter is a high-range differential pressure flow measurement device consisting of a standard orifice plate and a multi-parameter differential pressure transmitter. Orifice plate tapping refers to the method of extracting the differential pressure before and after the orifice plate. Common types of orifice plate pressure taps include: flange taps, corner taps, and radius taps (D-D/2 taps). In orifice differential pressure flow measurement systems, the choice of tapping method significantly affects measurement accuracy, installation complexity, and maintainability. RFQ Tabl......
