Product Description

The Fixed gas detection and gas alarm controller HD6000 4-way split-line LCD type (hereinafter referred to as the controller) is a 4~20mA split-line gas detection and warning system designed by our company for the industrial environment. The controller LCD display, not affected by external light, displays the gas name and concentration value and gives an audible and visual alarm when the concentration exceeds the standard. The use of internationalized icon indication, with instructions, simple and convenient operation.

The controller is characterized by good stability, high accuracy, and intelligent setting of parameters. With abundant external control ports, users can freely choose the type of sensors to be connected and the access ports and can carry out on-site detection and alarm through simple settings. When the index of a gas to be detected does not meet the set standard, the system will automatically carry out a series of alarm actions, such as sound and light alarm, air exhaust, tripping, etc. (depending on the user’s use scenario).

The controller has the advantages of fast response time, high reliability, low failure rate, easy maintenance, etc. It can be widely used in petroleum, chemical, liquefied gas, coal, pharmaceutical, metallurgy, municipal and other industries, and is the ideal choice for updating and replacing gas alarms. Hangwei Sensors are Best Fixed Gas Detection Controller Manufacturer.
