Help you solve all the troubles. . . . . . The company product range, quality assurance, welcome your purchase. Brief: LPG leak in there will be the first time, the site leaked flammable, explosive gas or toxic gas concentration data, transmitted to the gas alarm controller, by LPG alarm controller for data processing, marketing to Shandong - Jiangsu - Jiangxi - Hebei - Henan - Zhejiang - Liaoning - Tianjin - Dalian - Xinjiang - Gansu - Sichuan - Guangdong - Guangxi - Anhui - Fujian - Hubei - Hunan - Chongqing - Yunnan - Ningxia - Inner Mongolia - Jilin - Shanghai - Guizhou - Shaanxi - Shanxi Features ◆ accurate measurement sensors use import-sensitive components, with high accuracy, interchangeability, high reliability. ◆ digital signal and analog signal 4-20mA compared to standard current signal, before the exchange without first commissioning, gas detectors can always freely swapped positions, easier to maintain. The advantages of high accuracy, transmission distance, interference good. ◆ Explosion-proof can be used in factory conditions 1,2 dangerous places. ◆ easy maintenance and use of the components in the form of internal movement, field maintenance just replace components to complete. ◆ detector gas detector structure using die-cast aluminum shell material, dual-chamber structure designed to avoid accidental water, nearly dust, corrosion, and failure phenomenon, the volume is small, easy to install. ◆ sensor to protect the sensor probe part made of stainless steel, effectively play the role of anti-corrosion; through the sensor mesh stainless steel particles, good air permeability. ◆ Type approval: Fire Electronic Product Conformity Assessment Center ◆ Application Standard: GB15322.1-2003, GB12358-2006 electrical ◆ Power supply: DC24V + -15% ◆ Signal: Digital Signal ◆ Terminals: for wire cross-section 0.5 ~ 2.5mm2 ◆ Connection Cable: three wire cable sheathing line ◆ Wiring: three-wire ◆ Accuracy: ± 5% FS ◆ Response time: less than 30s environment ◆ IP rating: IP65 ◆ Temperature range: -40 ℃ ~ 65 ℃ (catalytic combustion) | - 40 ℃ ~ 65 ℃ (electrochemical, non-permanent) ◆ Humidity range: 10 ~ 95% RH (non-condensing) ◆ pressure range: 86 ~ 106KPa ◆ Storage temperature: -40 ℃ ~ + 85 ℃ ◆ Transmission distance: ≤1200m ◆ Detection of gas:% LEL, ppm,% VOL ◆ detection methods: natural diffused ◆ Detection range: 8-15m2 http://nxjuqian.cn/ http://lyafdz.net/ http://aqjuqian.com/ http : //yyhtjq.com/ http://cnjingniu.com/ http://bjq123.com/ http://gzjuqian.com/??http://scjuqian.com/ http://shjuqian.com/
