Product Description

■ 4~20mA.DC(Transmitter), RS-485 Modbus Communication, HART Communication(Option)
■ FND LOCAL DIGITAL DISPLAY
■ MODEL : QM-9500D

FEATURES

◉ QM-9500D continuously detects surrounding gases in a dangerous place ex-posed to potential gas leakage.
◉ The built-in high performance pump(Diaphragm pump) can quickly detect gas leakage.
◉ As the first built-in automatic HEATER & WATER drain solenoid valve type device,it dries humidity caused by water or temperature changes when external air comes in, and automatically drains water.
◉ Due to the RS-485 Modbus(Isolated) Serial and the Hart Communications, it con-sists of the Field-Bus Network.
◉ QM-9500D has the high-intensity LED Flash Warning Light.
◉ Without opening its cover, the magnetic key or computer monitoring system sets 1:1 transceiver type remote calibration and programs.
◉ Enclosure explosion-proof structure(by KOSHA).
