本特利990振动变送器明星产品
KM990轴振动变送器直接和电涡流传感器探头相连，中间不需前置器调理器，直接输出工业标准的4-20mA电流信号可直接接入DCS或其他相关系统。 一、主要功能
■信号输入、输出全隔离，抗干扰能力强。
■间隙输出(GAP.COM):指示被测体静止和动态是的位置状态,间隙电压-2VDC～-18VDC。
■对应振动信号0~F（um），输出4～20mA
■信号调理器电源:24VDC±10%，纹波小于10mv。
二、主要技术指标
■传感器输入：KM1100系列电涡流传感器
■轴振传感器输入点数：2个点
■系统输入/输出转换精度（含传感器）：
■记录输出：优于±1.0%（全量程）0~65℃
■显示：优于±1.0%（全量程）0~65℃
■量程:0～125um
■输出：标准信号:4～20mA;
■电源管理：每一个信号调理器电源独立工作，互不影响。
■安装方式：标准35mm导轨安装或螺钉安装
