选配项

TKL-121系列液位远传变送

TKL-121系列液位远传变送器是将磁性系统耦合过来的液位信号作用于传感器内的电阻链上的每 一个干簧管,引起输出电阻连续变化,从而引起测 量电压的连续变化,此电压与罐体液位成正比,通 过变送转换器,输出二线制4-20mA模拟信号,也可 以带现场显示和HART通讯协议。

Optional  attachment

Matched TKL-121 liquid level teletransmissiontransmitter

  TKL-121 liquid level teletransmissiontransmitter works the liquid level signal from magnetic system coupling onevery reed switch in the resistance chain inside the sensor, which gives riseto continuous changes of output resistance, thus causing the continuous changeof measuring voltage. This voltage is in direct proportion to the tank’s liquidlevel. Through the transmitting converter, it outputs two-wire system 4-20mAanalog signal, which can also be equipped with status display and HARTcommunication protocol.

TKWL-130系列磁致伸缩液位变送


TKL-130系列磁致伸缩变送器是将磁性系统耦合过来的液位信号,以间隔1.5μs发送的脉冲,精 确地测量液位计中磁浮子的位置。这个脉冲产Th的 磁场沿波导管向下传导。当磁浮子的磁场和脉冲电流磁场相遇时,产Th返回脉冲。敏感元件探测到这个返回脉冲。根据电流脉冲与返回脉冲之间的时 间,通过单片机计算出浮子的位置,确定被测液位和界位。

TKL-130系列产品适用于对测量精度要求高的 场合,也适用于高温型磁翻板液位计的远传变送,变送器输出二线制4~20mA DC信号,可带HART通 讯协议,也可输出RS485信号。

Matched TKL-130magnetostriction liquid level transmitter

  TKWL-130magnetostriction liquid level transmitter accurately measures the position of the magnetic floater in the liquid level  meter with the pulse sent at the interval of 1.5μs. The magnetic field produced by this pulse transmits downward along the waveguide. When the magnetic field of the magnetic floater meets with the pulse current of the pulse, reset pulse emerges. Then the sensitive element detects this reset pulse. According to the time between the current pulse and the reset pulse, the single chip can work out the position of the floater, thus confirming the measured liquid level and boundary.

  TKL-131 products apply to occasions withhigher requirements of measurement accuracy as well as teletransmission andtransmission of magnetic liquid level meter. The transmitter outputs two-wiresystem 4-20mA DC signals, which can be equipped with HART communicationprotocol and output RS485 signals.

安装使用和维护

1.液位计安装必须垂直,以保证浮球组件在主体管内能上下运动自如。                          

2.最好在容器与液位计之间装上截止阀,以便清洗和检修液位计时切断物料。                     

3.液位计主体管周围不容许有导磁物体靠近,否则直接影响液位计正常使用。                      

4.液位计安装完毕后,需要用磁钢进行校正,对翻柱导引一次使零位以下显示红色,零位以上显示白色。 

5.液位计投入运行时应先打开上端截止阀,再打开下端进料引液管阀门,让液体介质平稳进入主体管,避 免液体介质带着浮球组件急速上升,而造成翻柱失灵和乱蹦。(若发Th此现象待液面平稳后可用磁钢重新校正。)  

6.为了不使浮球组件在运输工程中损坏,故出厂前浮 球组件取出液位计主体管外。待液位计安装时打开底 部排污法兰,再将浮球重新装入主体管内,注意浮球 组件重的一头朝上,不能倒装。

7.根据介质情况,可定期打开排污法兰清洗主体管内 沉淀物。

Installation andMaintenance

1.   The liquid level metermust be installed vertically so as to make sure that the floater element can move up and down freely in the maintube.

2.  It is better to install a stopvalve between the containerand the liquid level meter so as to make it possible tocut off the material whencleaning and maintainingthe liquid levelmeter.

3.  Magnetic objects are not allowed to get close to the main tube of the liquid level meter, or it will directly influence the normal usage of the liquid level meter.

4.   After the installation of the liquid level meter, magnetic steel should be used to check, making the reversible column guide  display red below zero and white abovezero.

5. In actual operation, the stop valve at the upper end should be opened first, and then the feeding liquid guide tubevalve should be switched on to make the liquid medium enter the main tube smoothly in order to avoid the fact that the liquid mediumrises rapidly with the floater element, which may lead to malfunction and jumping of the reversible column. (If this happens, when the liquid level becomes smooth, magnetic steel can be used torecalibrate.)

6.To avoid the damage to the floater element in transportationprocess, before delivery, the floater element is taken out of the main tube of the liquid level meter. When installing the liquid level meter, first open the sewage disposal flange at the bottom, and then install the floater into the main tube. Pay attention to it that the heavier end of the floater element is upwards, which can’t beinversed.

7. According to different conditionsof the medium, the sewage disposal flange can be opened regularly to clean  the  sediment inside the maintube.
