毫伏变送器是一种应用相当广泛的工业自动化仪表。早期生产的仪表系列都有毫伏变送器这个品种,如DDZ-Ⅰ型、DDZ-Ⅱ型以及QDZ仪表等。最近生产的仪表系列,毫伏变送器都是用具体敏感元件配套的,组成热电偶温度变送器、热电阻温度变送器、应变式压力变送器、霍尔式位移变送器等。毫伏变送器分有直流毫伏变送器与交流毫伏变送器。 Millivolt transmitter is a widely used industrial automation instrumentation. Early production instrument series have millivolt transmitter this species, such as DDZ-Ⅰ type, DDZ-Ⅱ type and QDZ instruments. Recently produced instrument series, millivolt transmitter are supporting the use of specific sensitive components, composed of thermocouple temperature transmitter, RTD temperature transmitter, strain gauge pressure transmitter, Hall-type displacement transmitter, etc. . Millivolt transmitter sub-DC millivolt transmitter and AC millivolt transmitter.
