RR930N/RR940N

Flow Measurement

Indicators for Panel mounting

The RR900N series is a scaling conversion display unit for pulse signal input.
It is ideal for pulse output type sensors such as wheel flowmeter sensors.
In addition to an alarm function and digital signal processing functions such as linearization, it is equipped with pulse/analog output and a serial communication function to output converted values.
