1. Product summarize
SV-8104 Fixed (with display) combustible gas alarm detector, adopt imported gas sensor, based on the advanced principle of catalytic combustion type, can test a wide range concentration value of combustible gas.
SV-8104 big screen LCD display , can be online at the scene to observe the target gas concentration ;can output RS485 digital signal ,communicating with console or PC ;4-20 mA current output of three –way system ,the signal directly proportional to the measured concentration of gas .With two level alarming output ,used high/low alarming environment , sound /light alarm ;With soft /hard two kinds of correction methods ,no need opening can be completed the calibration work .
2. Product feature
Long life, low temperature resistance, anti-sulfide, silane gas poisoning.
The no contact way of Infrared Remote Control can complete zero and gain calibration.
Two special highlight flashing red LED lights, separately prompt high/low alarming, meanwhile the sound alarm send out the alarming voice, inform the staff at the first time, the two ways replay separately pulled, drive the other work of external control equipment.
Die –casting of stainless steel case for offshore platforms, and high temperature, humidity and other harsh environment.
Have a good seal, anti-corrosion and explosion –proof and anti-EMI, RFI function.
Show the concentration value of the scene 4-20 mA analog and RS-485 digital output signal.
