Product Detail

Professional Protection, Focused on Propane Gas Leak Safety

This product is an industrial-grade propane gas detector, employing a mature catalytic combustion detection principle, exhibiting high sensitivity and excellent selectivity for propane gas. It is widely applicable to hazardous locations with flammable gases, such as restaurant kitchens, factory workshops, and boiler rooms using liquefied petroleum gas, providing continuous and reliable safety monitoring.

Building a Proactive Safety Protection System

Immediate On-Site Alarm: When the propane gas concentration in the environment reaches the preset alarm value of 10% LEL, the detector immediately activates an audible and visual alarm, alerting on-site personnel.

Multi-functional Linkage Control: The device possesses powerful linkage output capabilities, capable of simultaneously or independently controlling multiple safety devices:

DC12V/1.5A Pulse Signal: Used to link with the emergency shut-off solenoid valve, instantly and automatically shutting off the gas supply.

AC220V/1A Passive Switch Signal (Optional): Can directly control AC220V powered exhaust fans, alarms, or other equipment without intermediate relays, simplifying system configuration.

Intelligent Remote Monitoring: An optional wireless transmission module allows alarm signals and data to be uploaded to the company's IoT monitoring platform, enabling remote, centralized security management and real-time alerts.

Durable Design, Unaffected by Harsh Environments: The detector housing is made of high-strength ABS material and undergoes special anti-static and anti-contamination treatment, effectively resisting interference from kitchen fumes, alcohol vapors, and other substances. This ensures long-term stable operation under complex conditions, minimizing false alarms and guaranteeing the authenticity and reliability of every alarm.
