用途 | |
HR-1151AP型绝对压力变送器的δ室(见下图)一侧接受被测绝对压力信号,另一侧被封闭成高真空基准室,然后将其转换成4~20mA.DC信号输出。它可以测量除气系统、蒸馏塔、蒸发器和结晶器等的绝对压力 |
通用技术性能和参数 | |
输出信号:4~20MA.DC二线制(模拟) |
电源影响:<0.005%/V
负载影响:电源稳定时,无负载影响。
测量精度:调校量程的±0.2%,±0.25%,±0.5%(标配精度为±0.5%,若选择其他精度请在订货选型时注明。)
迁移特性:最大正迁移量500%;最大负迁移量600%
注:① 负迁移量的绝对值,不大于一个工程大气压。
② 迁移后的上限或下限绝对值,均不应超过最大测量范围的上限值。
③ 差压流量变送器迁移会破坏开方特性,故不能进行迁移。
④ 绝对压力变送器不能进行负迁移。
阻 尼:通常可在0.2~1.67秒之间可调,当灌充惰性液或带远传装置时,时间常数会增大。
启动时间:<2秒,不需预热
工作环境:环境温度 -29~93℃(模拟放大器)
-29~75℃(数字/智能放大器)
-29~65℃(带显示表头)
环境湿度 0~95%
防护特性:防护能力 IP65
防爆类型:隔爆型 Exd II BT4-6
静压影响:零位误差:±0.5%最大量程限值,对于32MPa在管道压力下通过调零给予校正。
电磁辐射影响:0.05%最大量程值,接受辐射频率27~500MHz,试验场强3V/m。
指示表(%):电流表 标尺长44.5mm 精度±2%
液晶数显 精度±0.2%
振动影响:任何方向200Hz振动时,±0.05%/g。
安装位置:膜片未垂直安装,可能产生小于0.24KPa的零点误差,但可通过调零来消除。
重 量:4.5Kg(不包括附件)
