德国的Hottinge Baldwin有限公司开发出一种PDE型差压测量仪,可供使用的测量范围在10mbar至20bar之间。采用电池驱动和2至20mA的双线技术,有多功能显示装置,如数字测量值显示器和准模拟显示带。双线方案支配二个极限值继电器以及一个测量
Hottinge Baldwin GmbH in Germany has developed a PDE type differential pressure gauge that can be used in the measuring range between 10 mbar and 20 bar. The battery-driven and 2 to 20mA two-wire technology, multi-function display devices such as digital display and quasi-analog display. The two-wire solution dictates two limit relays and one measurement
