JB-TB-GDB18 Controler de alarmă pentru gaze combustibile

Descriere

The JB-TB-GDB18 combustible gas alarm controller is a multi-point monitoring gas alarm controller developed by our company. Este folosit pentru a detecta concentrația gazului de testat în aerul ambiant. It can be equipped with multiple detectors for detecting different gas components and simultaneously monitor multiple points centrally. This product also has four-bus, three-wire and two-bus interfaces, which can meet the use of detectors with various wiring methods.

This system uses a microprocessor as a control unit and a high-precision sensor as a detection component, with high sensitivity and fast response speed. When the concentration of the gas to be tested is detected in the environment and reaches or exceeds the warning alarm value, the controller immediately issues an audible and visual alarm to remind us to take safety measures in time, and starts the execution control unit to control the drive exhaust or other peripheral equipment to prevent poisoning accidents, explosions and fires, asigurând astfel siguranța vieții și a bunurilor.
