Resistance Temperature Detectors (RTDs) are widely used in industrial and laboratory environments for accurate temperature measurement. However, their wiring configuration plays a crucial role in ensuring measurement accuracy. The three main wiring types—2-wire, 3-wire, and 4-wire—differ in complexity, cost, and precision. 1. 2-Wire RTD Connection In a 2-wire configuration, one lead wire is connected to

1. Introduction In high-temperature or high-humidity industrial processes, steam and condensation can significantly affect the measurement accuracy and reliability of radar level transmitters. Water droplets or condensate films on the antenna surface may attenuate the radar signal, causing unstable readings or complete signal loss. This document outlines proven preventive and corrective measures to mitigate these
1. Evolution of Regulatory Classification 1.1 Early Classification (1981–2016) The earliest relevant regulation dates back to the Safety Supervision Regulation for Pressure Vessels (Labour and Boiler Regulation No. 7 [1981]).Article 80 explicitly classified pressure gauges alongside safety valves as “safety accessories”, requiring periodic verification at least once a year. This classification placed pressure gauges in
1. Introduction In cable installation, bending radius refers to the minimum radius a cable can be bent without causing mechanical or electrical damage. It is a critical factor in ensuring cable performance, longevity, and compliance with international standards. Ignoring bending radius requirements may lead to insulation cracks, conductor deformation, or signal degradation. 2. What Is

Resolution is one of the most overlooked specifications when selecting an ultrasonic level meter. Yet, it plays a critical role in determining how precisely the instrument can detect changes in liquid level. In this article, we’ll explain what resolution really means, show practical examples, and help you decide whether 0.1% or 1% resolution is right
A Distributed Control System (DCS) is essential in managing complex industrial processes, providing centralized control and monitoring while distributing the control tasks across a network of controllers. Used extensively in industries like manufacturing, petrochemicals, and utilities, a DCS helps ensure efficiency, reliability, and safety. In this blog post, we’ll explore the primary components of a
