DBW型温度变送器是DDZ——Ⅱ型仪表中的一个主要品种,在工业生产过程的检测和调节中获得了广泛的应用。温度变送器通常的用法是配用各种型号的热电偶或热电阻测量温差。由于DBW型温度变送器实际上是一个低电平直流毫伏转换器,因而用途颇多。在某些场合它还可以代替运算单元,起到信号综合和运算的作用。下面介绍的温度变送器的两种简单用法,经我们实践证明可靠。
DBW temperature transmitter is DDZ - Ⅱ type instrument in a major species, in the industrial process of detection and regulation has been widely used. Temperature transmitter is usually used with various types of thermocouples or RTD temperature measurement. DBW-type temperature transmitter is actually a low-level DC millivolt converter, which uses a lot. In some cases it can also replace the arithmetic unit, play the role of signal synthesis and operation. The two simple usages of the temperature transmitter described below are proven by our practice.
