I-87089W-G/S

8-ch Vibrating Wire Input Module

Features

Support 8 ~ 32 Vibrating Wire inputs.
Support 450 ~ 6000 Hz Vibrating Wire sensor.
Support channel to channel isolation.

Introduction

The vibrating wire sensor has a wire which is initially plucked by a series of electrical magnetic forces from a coil. The conductive wire after plucking is vibrating in a magnetic field. The wire will disturb the field, and then the coil can pick up the induced voltage change. The signal is amplified and detected by a VW readout device, or called VW reader. After plucking, there is no other force acting on this wire. When the transient response dies out, the reader can read a stable resonant frequency. The resonant frequency is function of the tension of this wire.

Applications

The I-87089W/S can be extended to 32 channels by connecting 3 extra DN-1618UB
