80G explosion-proof radar level gauge/material level gauge/level gauge

1. Product Introduction

Explosion-proof radar level meters are also commonly referred to as explosion-proof radar level meters or explosion-proof radar level meters, a high-frequency intelligent measuring instrument with intrinsic safety and explosion-proof type, specially developed for flammable, explosive, and high-risk industrial scenarios such as petroleum, chemical, coal chemical, oil and gas storage, and dust processing. The equipment adopts advanced high-frequency pulse radar measurement technology and relies on non-contact measurement methods, eliminating the safety hazards of traditional contact level gauges that are prone to corrosion, wear, jamming, and sparking. It can achieve continuous, stable, and precise level monitoring of liquids, slurries, granules, and powders under extremely harsh conditions such as flammable and explosive gases, dust, high temperature and high pressure, corrosive and humid conditions. As the core equipment of industrial explosion-proof measurement and control systems, this series of explosion-proof radar level meters has passed national explosion-proof safety certification. The entire machine excels in explosion-proof, dustproof, waterproof, and corrosion-resistant properties, with no mechanical moving parts, zero failure rate, and no daily maintenance. It perfectly meets various explosion-proof level requirements in industrial production sites, making it an upgraded product for high-risk working conditions to ｒｅｐｌａｃｅ traditional ultrasonic, floating, and guided wave level meters.

This explosion-proof radar level meter uses 80GHz high-frequency microwave detection technology at its core, offering shorter wavelengths, higher resolution, and more focused beams. It can easily penetrate interference media such as vapor, foam, dust, and fog, unaffected by temperature fluctuations, pressure fluctuations, or changes in medium viscosity or density. The device transmits high-frequency microwave signals directionally via antennas, which are reflected off the material surface and receive the echoes. It is equipped with high-precision intelligent algorithms to quickly calculate signal transmission time differences, accurately converting real-time object level heights to effectively solve industry pain points of traditional measuring instruments under explosion-proof conditions, such as data drift, large measurement blind spots, poor anti-interference issues, and low safety factors. With ultra-high measurement stability and industrial safety standards, this equipment is widely used in various explosion-proof high-risk production scenarios, providing reliable data support for industrial automation measurement and control, safe production, and refined material management.

2. Core Working Principle

The explosion-proof radar level gauge operates based on the principle of high-frequency pulse radar ranging and is a non-contact non-destructive measurement device. The instrument antenna continuously emits high-frequency electromagnetic pulse signals. After the signals penetrate media such as air, steam, foam, and thin dust inside the tank, they contact the material surface to form stable reflected echoes. The high-precision signal processing module quickly captures the echo signals, accurately calculates the time difference between microwave transmission and reception, and combines intelligent filtering algorithms and false echo suppression algorithms to automatically filter out clutter interference generated by pipelines, brackets, and stirring devices inside the tank, producing accurate and stable level data in real time. The equipment measures without contact, mechanical movement, or friction or collision throughout the entire process, fundamentally eliminating the risk of electric sparks. It fully meets safety operating standards for explosion-proof conditions, and can achieve 24/7 continuous monitoring. Its measurement accuracy and operational stability far surpass traditional explosion-proof measurement equipment.
