Click on View [ Dimension & Mounting / wiring terminal/The type of gas ]
 
 ■ Characteristic:
 
0、1、2、4~20、22mA current/mod-bus signal output 2 cable entries convenient to install
4 digits high-light LED,Magnet Pen set IIndependent gas chamber structure, and the sensor is easy to replace
Import sensor of high accuracy & anti-poisoning Own intellectual property rights with self-determination
Automatic zero-tracing, temperature compensating Explosion Prevention Mark ExdⅡCT6
2 Programmable Linkage Output Interface    
 
 ■ Working theory:
 
    GN8020-E Toxic gas detector first sample the signal from sensor,then deal the signal with the internal data processing, final output the consistence of ambient air by the signal such as 4~20mA , Mod-bus digital frame.
    The GN8020-E can use in system with our company's GN90000-B、GN90000-P、GN90000-F、GN90000-A、GN90000-S gas controller. Otherwise, through Linkage Output of relay, the GN8020-E can be joined with the host of fire control, and cut-over fire control system immediacy.
