VW0420 Analog VW Interface Instruction Manual
The VW0420 provides an interface between vibrating wire instruments and factory automation systems which support 4-20 mA sensors.
The VW0420 provides an interface between vibrating wire instruments and factory automation systems which support 4-20 mA sensors. The vibrating wire section measures the natural frequency and temperature of the sensor. The measurements are then converted to engineering units, unit converted etc. as required, and scaled to the 4-20 mA outputs. Setup of the device is straightforward, using a Windows host program connected via USB cable.

The VW0420: Vibrating Wire Isolated Analog Interface provides an interface between vibrating wire instruments and factory automation systems which support 4-20 mA sensors.
I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
