产品描述

概述

molbox RFM 是一个辅助单元,可使用 molbloc-L 层流和 molbloc-S 声速流元件进行质量流量测量。

molbloc 流量元件通过两个压力连接件和一根数据线连接到 molbox RFM 上。molbox RFM molbloc EEPROM 读取校准数据,并利用其内置的高精度参考压力传感器 (RPT) 测量 molbloc 的上游压力和下游压力。欧姆测量系统读取 molbloc 铂电阻测温仪的电阻,然后由此计算 molbloc 温度。利用存储在 molbox RFM 内存中的 molbloc 校准数据、压力、温度和气体属性,可计算出通过 molbloc 的气流流速。对于 molbloc-L 流量元件,在流量量程 10% FS 以下时,可以选择微量程选项来提高流量测量分辨度和精确度。

molbox RFM molbloc 流量元件应用广泛,适用于需要高精确度测量低气流的测量、测试和校准应用。对于主要考虑结构紧凑、量程可调性高、成本较低的应用来说,molbox RFM 是理想之选。第二种型号 molbox1+ 针对的优先考虑不确定度的应用。要配置质量流量校准系统,请查看随后几页,选择 molbloc 和压力相关校准,以便更好的覆盖您的流量量程和压力状况。molstic 安装系统和 COMPASS® for molbox 流量校准软件可以帮您完善系统。

技术指标

流量测量技术指标

molbox RFM 可测量通过 molbloc 流量元件的流量。molbloc-L 的流量量程、可用工作压力和压力差,或者 molbloc-S 的流量量程、绝压量程,取决于所使用的 molbloc 元件和校准选项。请参阅 molbloc-L molbloc-S 量程表,了解校准和量程详情。

molbloc-L 量程最高可达 3E4,可通过微量程选项提高在 10% FS 以下时的分辨率和精确度。对于 1E5-L molbloc,必须使用微量程选项才能达到技术指标。

molbloc-S(所有量程)

除了没有微量程以外,其他技术指标与 molbox RFM 相同。只要将 molbox RFM 连接到 molbloc-S 上,就会禁用微量程传感器。

精确度:包含线性度、迟滞和可重复性。

预测的稳定度:典型 molbox RFM molbloc 在典型环境下使用时一年内从零到范围值的最大变化情况。由于稳定度只能是一种预测,因此应该根据经验建立特定 molbox RFM 的稳定度。

测量不确定度:molbox RFM 流量指示相对于通过 molbloc 的流量真值的最大偏差,包括精确度、稳定度和 DHI 校准标准不确定度。molbloc 的测量不确定度技术指标仅适用于使用的是 molbloc 校准过的气体的情况。所有 molbloc 都针对 N2 校准过。其他气体的校准是可选的。并非所有规格的 molbloc 在所有时间,对所有气体都提供 DHI 校准功能。请在订购前检查是否可用。
