The GPD5 Mining Intrinsically Safe Pressure Sensor is designed for real-time pressure monitoring in underground coal mine applications, including sealed areas, and ventilation monitoring points.
The sensor converts collected pressure signals into standard RS485 digital signals and provides local pressure display and alarm functions. With high environmental adaptability and reliable intrinsically safe design, it enables accurate pressure monitoring and data transmission for intelligent mine safety management systems.
Key Features
RS485 Signal Communication
Converts pressure measurement signals into RS485 digital communication signals for seamless connection with underground monitoring and control systems.
Local Data Display
Equipped with a digital display to provide real-time visualization of measured pressure values at the installation site.
Audible and Visual Alarm
Integrated sound and light alarm functions provide immediate warning when abnormal pressure conditions occur.
Robust Environmental Protection
