Online explosive gas analyzer applied to chemical industry for hazard warning
Product Description:
Online explosive gas analyzer applied to chemical industry for hazard warning Performance and characteristics1 test two different gases simultaneously2 in the same domestic industry have no this technology application3 4-20mA, Rs485 main line system (optional)4 120dB explosion-proof sound-light alarm5 high brightness LED can be instructed in ten metres away6 the original imported sensor7 stainless steel shellRs485 and 4-20mA double output can access any field devices Calibrating wihtout open cover and makes operation more convenient. Certificates1.one patent of practical new technique.2.two patents of appearance technique.3.fire control type approval of the ministry of public security.4.National explosion-proof electric inspection.Characteristic of sensor1.plug and play any time2. High concentrations protection (applies only to catalytic sensor)3. High precision & wide range hardware VGA (variable gain amplifier) avoids the sensitivity decrease brought only by software amplification.4. Each probe contains a extra temperature sensor to compensate the impacts to gas sensor by temperature.5. Artificial intelligence compensation technology makes reading more smooth and stable.6. Sensor lifetime system from the viewpoint of sensor helps the user know whether the sensor need to replace or not.7. Double output of current completely satisfy the requirements of Dual-use machine.The compound gas transmitter of GQB-200A10 is applied for semiconductor, catalytic combustion, electrochemistry, nondispersive infrared and PID sensors and can be used between any two kinds of the above sensors. It’s the first choice of exceeding the imported products and complex gas ambients.Attention: GQB-200G10 cannot be applied for two catalytic combustion sensors working at the same time.Technical parametersType of sensorCatalytic combustion sensorseiicIonductor sensorElectrochemical sensorPID sensorIR sensorOperating current<400mAWorking voltageDC24V±5VSignal outputs4-20mA, RS-485(optional)display3+2 LED display3-color LED lightsRelay outputAC220V/5A or DC24V/5ADetection gasCombustible gasCombustible and toxic gasToxic gasTVOCCombustible gasCO2Detection range0-100%LEL0-100%LEL0-100ppm0-100ppm0-30%vol0-100ppm0-100%LELAlarm concentrationadjustableT90<15s<15s<30s<10s<30sDetection precision3%1%1%1%3%Zero drift2%/yearLifetime of detector>3year>3year>2year>1year>5yearAllowable application areasHazardous location zone I&IIAlarm of sound & light120dB red color alarmAmbient conditionOutdoor usageRelative humidity10~95%RH(No condensation)Atm press86~106KpaOperation temperature-40ºC~+70ºC-40ºC~+70ºC-20ºC~+50ºC-20ºC~+50ºC-40ºC~+70ºCStorage temperature-40ºC~+85ºC-40ºC~+85ºC-25ºC~+50ºC-25ºC~+50ºC-40ºC~+85ºCTransmission cableThree-core shielding line for 4-20mA; four-core shielding line for RS485 Wire diamete 1~1. 5 mm2Transmission range4-20mA≤2Km; RS485≤1.2KmElectric connectorM20*1.5(cast aluminium); G3/4’’(stainless steel)Explosion-proof gradeExdIICT6weight2.5kg(cast aluminium); 4kg(stainless steel)Protection gradeIP65 standard (IP66,IP67 optional)
