Blt100 浮筒液位变送器的详细信息
    BLT100双线浮筒液位变送器

    浮筒液位变送器BLT100 可靠性高 4至20mA回路供电输出 高达130℃的液温 本地可编程指示器 至多有两个报警输出 有Ex应用程序 概要说明 BASI BLT100 液位变送器是一种浮筒液位变送器。其工作原理是通过特别的磁性浮筒连续开关级联簧片开关,将一根保护管移开。簧片开关作用于电阻元素。 矩阵变换电路,用测量标准改变整体矩阵变换电路的电阻线形比例。BLT100提供了一个双电线的4至20mA的输出信号,该信号带有6到12mm的液位分辨率。还有一个集成的回路的供电可编程液晶显示器指示器。使用这种智能设备,同时配备两个隐形按钮,操作员可以实现屏显示屏范围编程、装置较准,或警报输出编程。输出可以带动两个外部继电器作为警报或简单的通电/断电控制。该BLT100 当超声波或电容式变送器由于泡沫、密度大的蒸汽或液体表面的非均质气层而无法工作的时候,BLT100 液位变送器就非常有用。在外部应用的情况下,必须用一个固有的安全电力供应装置或齐纳阻挡层。 技术规格 工艺流体: 液体,密度0.65g/cm3 输出信号: 双电线,4-20mA 范围: 300到3000mm 零点和量程: 电位计±0.20% 报警输出: 2个集电极开路输出门40VDC/10mA 负载极限: 0 - 820Ω,24V直流电 指示器: 4个数字液晶显示器或LED指示器,高度14mm 配置: 通过指示器上的按钮 保护级别: IP65  耐风雨 加工压力: 20bar 安装 供电电压: 10-30V直流电 环境温度: -20到70℃ 加工温度: -40到130℃ 电气连接: 线缆索紧 工艺连接: G2 或者 NPT2 接触液体的部件: AISI 316L 大致重量: 取决于应用情况 性能 度: 6或12mm 电磁兼容性: EN 50081-1,EN 50082-2,89/336/EEC 订货信息 BLT100 分辨率、长度、安装、指示器、报警器、垂直调整 高6mm×指定Q14 G 2" A液晶显示器 1 1报警器×None L 12mm p; Q17 NPT 2" C LED 2  2个报警 A  选择 安装 F 法兰×None×None 产品英文描述:FLOAT LEVEL TRANSMITTER BLT100 High reliability4 to 20 mA loop-powered outputUp to 130 °C fluid temperatureLocal programmable indicatorUp to 2 alarm outputs availableEx applications availableGENERAL DESCRIPTIONSThe BASI BLT100 level transmitter is an float level transmitter. The operating principle is based on a consecutive switching of the cascaded reed switches by the special magnetic float, moving alongside a protective tube. The reed switches act on the elements of a resistormatrix, changing the total matrix resistance in linear proportionality with the measuring level. The BLT100 provides a 2-wire 4 to 20 mA output signal with 6 or 12mm level resolution. An integrated loop-powered programmable LCD indicator is also available. Using this smart device, equipped with only two hidden buttons, the operator can realize display range programming, device calibration, or programming of the alarm outputs. The outputs (Open Collector type) can drive two external relays as alarms or simple ON/OFF control. The BLT100level transmitter is very useful in applications where ultrasonic or capacitive transmitters would not work because of the foam, dense vapor, or non-homogeneous gas layer above the liquid surface. In case of Ex applications, an intrinsically safe power supply unit or a Zener-barrier must be used. TECHNICAL SPECIFICATIONSProcess fluid : Liquid, density 0,65g/cm3Output signal : Two-wire,4-20 mARange : 300 to 3000mmZero and span : Potentiometer ±0.20%Alarm output : 2 open collectors 40VDC/10mALoad limitation : 0 - 820Ω at 24VDCIndicator : 4 digit LCD or LED- indicator height 14mmConfiguration : By pushbutton on the indicatorProtection class: IP65 weather-proofProcess pressure : 20bar INSTALLATIONSupply voltage : 10 - 30 VDCAmbient.temp : -20 to 70°CProcess.temp : -40 to 130°CElectrical connection : Cable glandProcess connection : G 2 or NPT 2Wetted parts : AISI 316LApproximate weight : Depending of application PERFORMANCEAccuracy : 6 or 12mmEMC : EN 50081-1, EN 50082-2, 89/336/EEC ORDER INFORMATIONBLT100RESOLUTION  LENGTH    MOUNTING  INDICATOR  ALARM    VERTICAL ADJUSTMENTH 6mm
