Product Introduction
RAEAlert LEL is an intelligent, integral explosion-proof (d) structure, fixed installation combustible gas detector. It can be widely applied in fields such as petroleum, petrochemicals, metallurgy, chemical engineering, environmental protection, papermaking, printing and dyeing, municipal engineering, scientific research, education, and national defense.
Product Features
Smart Sensor: Adopting intelligent sensors, it has stronger anti poisoning and anti-interference capabilities, and realizes sensor interchangeability, offline calibration, and zero point self calibration functions
Multiple signal outputs: adjustable standard 4-20mA (three wire system) RS485 Modbus、 Three level switch output (normally open/normally closed optional), which can be easily connected to industrial control systems such as PLC/DCS, or used as a standalone control
Friendly human-machine interface: Large dot matrix LCD display, supporting both Chinese and English interfaces; No need to open the cover, infrared remote control operation, single person maintenance; Local alarm indication, integrated sound and light alarm (optional)
Prevent misoperation: The instrument has over range and reverse polarity protection, which can avoid the danger caused by improper human operation
Rich electrical interfaces: with various electrical interfaces such as 3/4 "NPT F, 3/4" NPT M, 1/2 "NPT F/M, G3/4 F/M, etc., available for users to choose from
International certification: Through ATEX, UL, CSA and other certifications, it has international high-end quality
