简介
YJTT-150系列差动远传压力表用于测量对铜及其合金不起腐蚀作用的液体、气体和蒸汽的压力。仪表带上阻尼器后，可测量脉动、冲击、突然卸荷介质的压力。带上隔膜部分后，可测量粘度大、有腐蚀性介质的压力。本仪表除就地进行压力指示外，还连续输出与被测压力信号成线性的4～20mA或0-10mA直流信号。可以与分别DDZ-Ⅲ电动单元组合仪表中的显示、记录、调节仪表联用，组成自动记录、调节、控制等系统。适用于石油化工、冶金、电站、轻工业等部门使用。
YJTT-150 series differential motion remote transmitting pressure meter is used for measuring pressures of liquids, gases, or vapors that do not corrode copper and its alloys. If equipped with shock damper, this meter mayalso measurePressures caused by pulsation, concussion, and sudden unloaded mediums. If equipped with diaphragm, it may also be used to measure pressures of such mediums with big viscosity and causticity.This instrument provides not only local pressures with indication, but also continual output of 4～20mA direct current signal with linear relationship with its testee pressure signal. It may compose automatic recording, adjustment, control, or other systems, in combination with displaying, recording, and adjusting instruments of DDZ-II electricity-powered units, applicable for applications in such departments as petroleum chemical industry, metallurgy, or light industry.
