美国福禄克公司近日推出一款回路排障专家——FLUKE-773。无需“断开回路”即可测量4至20 mA信号。其“同步毫安输入/输出”功能是调节阀,开度阀,智能阀的排查利器。操作方式为把钳子夹在阀门的阀位反馈回路,同时输出你想要的mA激励信号给激励回路,由于773将这两个mA信号值同时适时地显示在屏幕上,用户一目了然的对 Fluke Corporation recently introduced a circuit troubleshooting experts - FLUKE-773. Measure the 4 to 20 mA signal without “disconnecting the loop”. Its “synchronous milliampere input / output ” function is regulating valve, opening valve, intelligent valve troubleshooting device. The operation mode is to clamp the pliers in the valve position feedback loop and output the mA excitation signal you want to the excitation circuit at the same time. Since the 773 displays these two mA signal values ​​in real time on the screen, users can easily understand
