 GTD-5000Ex pumped combustible gas detector
■ Built-in sampling pump, faster leak response
■ modular sensor, easy to replace
■ Modbus communication
■ PoE online detection
■ can be achieved ppm, LEL, Vol units display
■ Fixed gas flow
◤ use built-in sampling pump to achieve rapid response to combustible gas leakage
 Built-in microprocessor to achieve self-diagnostic function
◤ with a box sensor, the replacement is more simple
◤ use digital flow sensor to maintain a fixed flow
¢ According to a variety of detection principles, from low to high concentration of gas detection
¢ long-term stability of the quality and proven test principle
◤ excellent LCD display, display a variety of information
¢ 4-digit gas concentration monitor
◤ 4-20mA DC output signal
↑ Easily monitor configuration via RS-485 Modbus serial data communication or PoE (optional)
 Level 2 alarm, single fault display and relay contact output
◤ Signal is connected to the 3-wire of the power supply
 Single calibration and maintenance
