Product Description

Product Description
Low Power ≤5W Energy-Efficient Design Reduces Long-Term Costs Gas Detection Controller
HBS11b Combustible Gas Alarm Controller 
Product Description 
The HBS11b Combustible Gas Alarm Controller is a single-pointmonitoring gas alarm controller developed by our company, used to detectthe concentration of target gases in the ambient air. It can manage4-20mA system detectors that detect different gas components. When thedetected gas concentration in the environment reaches or exceeds thepreset alarm value, the controller immediately activates audible and visualalarms, prompting timely safety measures and starting actuators to control ventilation or other external equipment, preventing poisoning accidents,explosions, and fires, thereby ensuring the safety of life and property.
Product Features
→Utilizes STM32 microprocessor
→Human-machine interface uses a large-screen LCD display andadvanced keyboard interaction 
→Leveraging its dedicated anti-interference software techniques, thesystem achieves a software-based solution for machine faultdiagnosis.
→High reliability and maintainability
