YTT-150系列差動遠傳壓力表
YTT-150 Series Differential Motion Remote Transmitting Pressure Meter
簡介
YTT-150系列差動遠傳壓力表用于測量對銅及其合金不起腐蝕作用的液體、氣體和蒸汽的壓力。儀表帶上阻尼器后，可測量脈動、沖擊、突然卸荷介質的壓力。帶上隔膜部分后，可測量粘度大、有腐蝕性介質的壓力。本儀表除就地進行壓力指示外，還連續輸出與被測壓力信號成線性的4～20mA或0-10mA直流信號。可以與分別DDZ-Ⅲ電動單元組合儀表中的顯示、記錄、調節儀表聯用，組成自動記錄、調節、控制等系統。適用于石油化工、冶金、電站、輕工業等部門使用。
YTT-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 measure
Pressures 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.
