DF9014 Positive and negative rotation speed monitoring deviceDetailed product description：

The DF9014 forward and reverse speed monitoring device can monitor the speed and direction of rotating machinery. It has a reverse speed protection group that requires two channels of sensor input signals to output its corresponding speed and reverse alarm status.
The speed is displayed on the panel by a digital tube and converted into a 4-20mADC analog signal. This instrument has an alarm function, which outputs overspeed and reverse alarms through their respective contact signals. Based on advanced intelligent design, this instrument can also remember historical maximum values. In addition, the instrument supports optional RS485 communication interface, and the measured values, alarm status, etc. of the instrument can be read through the data bus.

DF9014 forward and reverse rotation meter is suitable for various rotating machinery, such as pumps, water turbines, etc.
