The Ex HK-7100A Combustible Gas Detector, based on catalytic principle, is designed for continuous detecting and monitoring of combustible gases in ambient air over the range of 0-100% LEL(lower explosive limit) and provides a 4~20mA output signal that can be connected to a controller, PLC,DCS or similar instrumentation.
. ADVANCED MCU TECHNOLOGY.
. SMT AND INGETAL DESIGN—Enhance performance and reliability.
. CURRENT TRANSMISSION–Extremely extends the distance of signal transmission.
. CENTRALIZED POWER SUPPLY AND REGIONAL POWER SUPPLY
. LED DISPLAY—Display real-time concentration and operating statues of detector.
. SIGNAL TRANSMISSION—Send measured concentration signal to controller.
. INDOOR AND OUTDOOR USE—Suitable for the harshest environmental conditions.
. UNIQUE MAGNETIC PEN DESIGN—Operate detector through magnetic pen.
. SELF-PROTECTION FUNCTION—Prevent high concentration gas from damaging detector.
. IMPORTED CATALYTIC COMBUSTION SENSOR—Advanced performance with stable measurement, high sensitivity, anti-poisoning, and resist influence.
. SENSOR DIAGNOSTIC FUNCTION—Provide alarm and prompt while sensor fault or ageing.
