產(chǎn)品簡介
----------------------------------------------------------------------
通用天然氣氣體泄漏濃度檢測探測報(bào)警器(Natural Gas Alarm)，簡稱天然氣檢測器，或天然氣探測器，或天然氣報(bào)警器，主要針對(duì)天然氣（即甲烷）氣體泄漏濃度檢測、濃度顯示及濃度超標(biāo)后的聲光報(bào)警提醒，并可聯(lián)動(dòng)然氣電磁閥，一旦泄露，及時(shí)切斷。
目前，國家對(duì)天然氣氣體泄漏檢測報(bào)警器要求嚴(yán)格，廠家必須具有*，并且機(jī)器上貼有3C標(biāo)簽及消防標(biāo)簽，天然氣氣體報(bào)警器由氣體探測器(Gas Detector)和氣體報(bào)警控制器(Gas Controller)，氣體報(bào)警控制器必須配置備電。
氣體簡介：天然氣主要組成部分為甲烷（85%）和少量的乙烷、丙烷等氣體。也有人稱為“沼氣"。我們這里主要是說天然氣管道的天燃?xì)?。天然氣的檢測量程為0-LEL。天然氣比空氣輕，所以天然氣探測器的安裝位置在泄漏源的上方。
天然氣氣體報(bào)警器使用比較多的場所：加氣站、酒店廚房、學(xué)校餐廳等存在天然氣氣體的場所。
天然氣氣體報(bào)警器產(chǎn)品特點(diǎn)：
◆ 測量準(zhǔn)確：傳感器采用進(jìn)口氣體敏感元件，精度高，零點(diǎn)漂移小，抗中毒性能好。
◆ 防爆設(shè)計(jì)：可用于工廠條件的1、2區(qū)危險(xiǎn)場合。
◆ 維修方便：傳感器采用數(shù)字化模組設(shè)計(jì)，現(xiàn)場更換時(shí)無需校零、標(biāo)定。
◆ 聲光報(bào)警：氣體探測器可選配專用的防爆聲光報(bào)警器，實(shí)現(xiàn)現(xiàn)場聲光報(bào)警。
◆ 濃度顯示：氣體探測器可選配液晶濃度顯示，現(xiàn)場實(shí)時(shí)顯示濃度。

Natural Gas Alarm
Natural gas alarm mainly detects natural gas (i.e. methane), detects and displays mainly the concentration of natural gas, sending audible and visual alarm when the concentration exceeding the scheduled standard. Linking together with gas solenoid valve, cut off gas supply immediately once leakage occurs.
The state is strict in gas alarm at present, the factory must own 3C authentication. All equipment must stick 3C label & Explosion-proof label. Natural gas alarm is consists of detector and alarm control, the last must configure power reservation.
Natural gas alarm is used in more sites, such as gas station, kitchen, canteen and so on, in which gas exists.
