Analysis of Industry Gas Risks

Packaging material production involves various chemical processes such as printing, gluing, and heat sealing. These processes often release volatile organic compounds (VOCs), combustible gases such as methane or ethane, and toxic gases such as hydrogen sulfide and sulfur dioxide. The container industry is even more complex, especially when transporting hazardous chemicals, where residual gases or leaks may trigger chain reactions. According to industry data, global economic losses caused by gas-related accidents amount to hundreds of millions of dollars annually, not to mention the threats to personnel health.

For example, phosphine used in container fumigation processes may cause acute poisoning if not detected in time. In packaging workshops, excessive sulfur dioxide emissions not only affect air quality but may also corrode equipment, increasing maintenance costs. These risk points require enterprises to establish systematic gas monitoring mechanisms, not only to comply with national safety standards such as GB/T 50493, but also to improve overall operational efficiency. Nexisense solutions are designed specifically to address these pain points. Through real-time monitoring, they help enterprises identify hazards early and prevent accidents.

Practical Advice for Selecting Gas Detectors

With a wide range of gas detection equipment available on the market, how should companies choose the right model for the packaging and container industry? First, prioritize purchasing directly from manufacturers such as Nexisense to ensure seamless product quality and after-sales support. Second, verify product certifications, including Type Approval Certification (CPA) and Explosion-proof Certification (Ex), which are fundamental guarantees of equipment reliability.

The brand of the core sensor is also crucial. Original imported sensors typically offer better sensitivity and longer lifespan. Finally, refer to practical cases: Nexisense has served multiple large packaging enterprises and logistics companies. For example, in a container terminal project, it successfully monitored gas levels in hundreds of containers, preventing potential explosion risks. When selecting equipment, also evaluate detection range, alarm thresholds, and communication protocols such as Modbus RTU or 4–20mA signal output to match existing systems.

Installation and Usage Guidelines

Proper installation is the prerequisite for effective performance of gas detectors. Depending on gas properties, installation positions must be adapted accordingly. For gases heavier than air, such as sulfur dioxide, detectors should be placed 30–60 cm below the leakage source. For gases lighter than air, such as hydrogen, install the detector 30–60 cm above the leakage source. Oxygen detection can be positioned flexibly above or below, while toxic gases should be within 1 m horizontally from the source, and combustible gases within 7.5 m.

Gas density can be judged by its vapor density: greater than 1 indicates heavier than air, otherwise lighter. Environmental factors such as ventilation conditions and potential leakage points should also be considered. After installation, regular calibration is essential. Every 3–6 months, use standard gases for calibration to maintain accuracy. Nexisense provides detailed manuals and online support to help users avoid common mistakes such as neglecting explosion-proof requirements or improper wiring leading to short circuits.

During use, pay attention to equipment maintenance: clean the sensor surface to prevent dust accumulation; check power stability to ensure steady 24V DC supply. If an alarm is triggered, immediately evacuate personnel and investigate the source. This is not only a safety measure but also a way to optimize production processes.

Application Scenarios of Sampling Methods

Gas detection in different environments requires appropriate sampling methods. In open spaces such as packaging workshops, diffusion sampling is the simplest option: gas naturally diffuses to the sensor for real-time monitoring without additional equipment.

For gases inside pipelines, such as container ventilation ducts, pipeline sampling is more suitable. Simply drill a hole in the pipeline and install a gas cup to directly extract samples. Pump suction sampling is ideal for high-pressure or high-speed flow environments. A vacuum pump extracts gas samples, and after detection, they can be returned to the pipeline to avoid waste. This method is particularly suitable for continuous monitoring during container transportation to ensure cargo safety.

Nexisense products support multiple sampling integrations, allowing users to switch modes according to site requirements for enhanced flexibility. For example, in high-temperature environments, high-temperature resistant probes can withstand temperatures above 150°C, suitable for heat-treatment packaging lines.
