产品详情:FLOWEVO / FLOWEVO plus 基于红外吸收原理,在精度、可靠性和效率上都遵循高的标准。使用光学原理,模块不会受磨损、或发生化学反应。几乎无需任何维护保养。利用红外原理为基础,通过检测气体的独特吸收光谱,从而做出准确的定量分析算出其浓度值。所有被测量气体吸收红外辐射在一个不同的光谱范围也就叫做“指纹”,从而保障良好的气体选择性,减少交叉干扰影响。最终得到的易于使用的浓度信号,是在考虑到所有的温度漂移影响之后,对浓度信号做补偿得到的综合评估值。所有FLOWEVO / FLOWEVO plus产品都选配恒温外壳,具有恒温隔热的功能。FLOWEVO / FLOWEVO plus的外壳为铝制外壳,配备软管连接,用以防止传感器机械损坏,并保证在检测过程中气体的正常通入。在软管与气室的连接端口使用内径3mm和外径5mm的接口,以保证软管与气室的正确连接。外壳配备了纤维隔热层,以确保在高环境湿度下外壳内不会有冷凝蒸汽。产品优势:&blacksquare 高选择性:受其他气体的交叉干扰影响小&blacksquare 传感器寿命长:使用光学原理,使用寿命长达10年&blacksquare 快速响应时间: T90在快速模式下小于3秒&blacksquare 稳定可靠的红外光源配备镀金气室,漂移小,延长校准周期&blacksquare 所有FLOWEVO / FLOWEVO plus产品都可配备有效消除光源的杂散光铝制恒温外壳FLOWEVO plus特性升级:&blacksquare 低噪声,快速响应时间&blacksquare 集成主动加热,以提高传感器的稳定性,防止内部潮湿&blacksquare 支持RS232和RS485数字接口&blacksquare 支持不同的模拟接口&blacksquare 可提供主动气室压力补偿&blacksquare 标准24VDC电源输入技术参数 FLOWEVO / FLOWEVO plus:FLOWEVOFLOWEVO plus检测原理NDIR 非分散式红外(双光束)检测量程详见列表供气方式泵吸式尺寸详见机械图纸管路连接3mm 内径, 5mm 外径(标准)读取噪声ABS(典型值)±0.1%FS@ T90 14sec (标准模式)±1%FS @ T90 3sec (快速响应模式)±0.075%FS @ T90 3sec读取频率Max 2.5HzMax 10Hz响应时间(T90)T90 14sec (标准模式)T90 3sec (快速响应模式)T90 3sec数字分辨率(@零点)1 ppm ...0.1 Vol.%最低检测下限 (3sigma)≤ 1 % FS(典型值)重复性≤ ±1 % FS线性误差≤ ±1 % FS ( 根据传感器类型而定)稳定性(零点)≤ ±2 % FS /12月稳定性(量程点)≤ ±2 % FS /12月温度漂移 (零点)≤ ±0,1 % FS 每°C温度漂移 (量程点)≤ ±0,15 % FS 每°C压力漂移0.1 % up to 0.2 % 读取值每mbar工作温度0 °C 到 50 °C存储温度-20 °C到60 °C环境湿度0 %到95 %相对湿度(非冷凝 )环境压力800 到 1200 mbar预热时间 2 分钟(冷启动) 30 分钟 全规格流量0.1到1.0 L / min (恒定流量)数字输出Modbus ASCII RTU TTL2400-115.200 auto Baud/ auto FrameSingle Wire2400-115200 Auto baud rate, auto frame- Free ASCII- Modbus ASCII- Modbus RTU- EVO Modbus ASCII- EVO Modbus RTU 9600, 8, none, 1- SCII Modbus RTU选配:模拟量输出选配额外的控制器0 / 4 … 20 mA (带S-Connect PCB)0 / 0.2...1V (带S-Connect PCB)选配0 / 4 … 20 mA Isolated (3kV/rms)4-20mA , 最大负载 600Ω 0-2VDC , 最小电阻负载 2kΩ 0-5VDC , 最小电阻负载 2kΩ 0-10VDC , 最小电阻负载 2kΩ 选配:数字量输出选配额外的控制器RS 232 (带S-Connect PCB)RS 485 (带S-Connect RS485 PCB)集成RS232RS485工作电压3.3 到6 V DC ± 5 %10-26VDC, 推荐24VDC电流不加热 240mA@5V ( average )加热Max 1.3A @24V功耗不加热 800 mW加热11 W @24V for Type II/III9 W @24V for Type I (73)17 W @24V for Type I (113mm...153mm)21 W @24V for Type I (233mm)31 W @24V for Type I (333mm)加热选配额外的加热控制器所有 FLOWEVO 都可配备压力补偿环境压力补偿环境压力补偿气室压力补偿 (选配)定制化协议不支持支持检测原理非分散式红外(双光束)测量范围见列表供气流动式尺寸参考机械尺寸数据软管连接3mm 内径, 5mm 外径响应时间 (T90)大约12 s (@ 0.7 L/min)分辨率 (@zero)1 ppm ... 0.1 Vol.%检测下限 (3sigma)≤ 1 % FS (typically)重复性≤ ±1 % FS线性误差≤ ±1.0 % FS ( or ≤ ±1.5 % FS depend on version)零点漂移≤ ±2 % FS during 12 month / 月满量程漂移≤ ±2 % FS during 12 month / 月温度漂移(零点)≤ ±0,1 % FS per °C温度漂移(满量程)≤ ±0,15 % FS per °C压力漂移0,1 % up to 0,2 % Value per mbar运行温度0 °C up to 50 °C存储温度-20 °C up to 60 °C环境湿度0 % up to 95 % rel.
