Online multi-Gas Detector KB-501AG

Gas detector KB-501AG is a new type of multi-gas detector which used advanced electrochemical sensor,catalytic combustion sensor,infrared sensor and microcontroller, employed sophisticated SMD technology. It has following advantages: good repeatability,high resistance to humidity-temperature jamming, long performance life and simple operation. It is applied to inspection for gas concentration in industrial environments.


KB-501AG can translate the appointed gas concentration signals into digital signals display. Three-wire system 4~20mA electric current signals output, with long-distance transmission and high anti-interference capacity. In addition, it has two-stage alarm function with acoustic and light signals.


Common applications is gas safety inspection and alert for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, etc.


Features

l Cast aluminum housing;

l Imported sensor;

l Intrinsically safety circuit design;

l High brightness LED digital display, clear and direct;

l Timely alert with acoustic and light alarm signals;

l Three-wire system 4~20mA standard signals output and four -wire RS485

l Possible to connect to DCS system directly;

l The probe has following advantages: high sensitivity, quick-response capacity, long performance life and short polarization time.

l With a manual controller (optional units) used for adjustment of parameter;

l Function of infrared remote control operation (remote-control is optional units).
