Overview Radar level transmitters are instruments that use microwaves to measure liquid levels based on the time or frequency of microwave propagation through air. They offer non-contact, high-precision measurement that is unaffected by temperature and pressure, making them widely applicable across various industrial sectors. 1. Concept and Role of Dielectric Constant The dielectric constant, also […]

The instrument calibration process must strictly follow the “Metrology Calibration Regulations” (e.g., JJG882-2019) and the technical requirements of the equipment. Based on industrial field operations, the process can be broken down into six key stages. Each stage includes clear operational points and data recording requirements. The detailed process is as follows: 1. Preparation Phase (Pre-calibration

In the instrumentation industry, theoretical knowledge is like a wrench in your hand—seemingly simple, but essential when it’s needed. Whether you’re preparing for a certification exam or just looking to build a solid foundation for daily work, understanding circuit diagrams, sensor principles, and troubleshooting logic is crucial. This series will keep updating, providing both theoretical

Instrumentation cables are specialized cables used for transmitting low-voltage, low-current signals in industrial control systems. These cables are vital for ensuring accurate communication and control between various devices in automation systems. Below is a detailed exploration of the common types of instrumentation cables, their characteristics, and suitable applications. 1. RVVP: Copper Conductor, PVC Insulated and

In the field of instrumentation, theoretical knowledge is like the wrench in your hand—it may seem unimportant, but when it’s needed, it plays a critical role. Whether you’re preparing for an entry-level certification or want to solidify your foundation in practical work, topics like circuit diagrams, sensor principles, and troubleshooting techniques are crucial.

Preventing water ingress in explosion-proof electrical equipment is essential to ensure safety and operational reliability. Below is a detailed guide to implementing effective measures for this purpose. 1. Choose the Right Protection Level IP Protection Rating: Select equipment with an Ingress Protection (IP) rating appropriate for the environment. For wet or damp locations, devices with

Overview This guide outlines the fault analysis steps for four key measurement control systems: temperature, pressure, flow, and level control systems. Each system is analyzed based on specific fault scenarios, providing clear steps to diagnose and address common issues. 1. Fault Analysis of the Temperature Control System When analyzing faults in the temperature control system,

Ensuring the compliance of measuring and testing instruments is essential for maintaining accuracy, reliability, and legal adherence in various industries. Here’s a detailed guide on how to evaluate the compliance of such instruments: 1. Understand Legal and Regulatory Requirements Compliance starts with understanding the legal framework governing measuring instruments. National Standards and Regulations: Metrological Verification

Maintenance management in the instrumentation industry is a specialized field that focuses on ensuring the accuracy, reliability, and functionality of measurement and control devices. Given the critical role of these instruments in sectors like manufacturing, healthcare, energy, and aerospace, a systematic approach to maintenance is essential.
