Process Signal Info Logger - Smart Reader Plus 7

Recording process signals is easy and convenient with the SmartReader Plus model 7. With seven input channels it is ideal for monitoring (through commercially available transducers) a wide variety of measurement parameters. All process signals can be displayed in their own engineering units using the simple equation editor in ACR's TrendReader Software for Windows.

Applications : Monitoring temperature, relative humidity, pressure, wind speed, current, voltage, power, flow, tank levels; SCADA troubleshooting; and more.
