H—1型油罐遥测液面仪是用于测量石油类、液态烃类、酸、碱、醇类的常压贮罐和高压贮罐液面高度的自动化仪表,全套仪表分为一次表(变送器)和二次表(显示仪)两个单元仪表配套使用,其中变送器又分为常压罐和高压罐两种表型,分别使用在常压贮罐和高压贮罐的不同场合。一次表属检测和编码单元,安装在被测液罐上,通过其测量和传动系统把液面高度的线性变化转换为编码机构的角位移。编码机构是一个接触式轴角编码器,把角位移转换为对应于高度变化的编码信号,通过传输电缆输送给二次表进行译码显示。
H-1 tank telemetry level gauge is used to measure the oil, liquid hydrocarbons, acids, alkalis, alcohols, atmospheric pressure tank and high pressure tank liquid level automation instrument, a full set of instruments is divided into a table ( Transmitter) and the secondary table (display instrument) supporting the use of two unit meters, of which the transmitter is divided into two kinds of atmospheric pressure tank and high pressure tank were used in the atmospheric pressure tank and high pressure tank different occasion. A table is a detection and coding unit, installed in the tank under test, through its measurement and transmission system to the linear change of the liquid level is converted to the encoding mechanism of angular displacement. The coding mechanism is a contact type shaft angle encoder, and the angular displacement is converted into a coded signal corresponding to a change of height, and is transmitted to a secondary table for decoding and displaying through a transmission cable.
