AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules
Check the manufacturer’s specification for the sensors frequency
and excitation range before picking the begin/end frequencies and
excitation voltage.
For example, the following AVW200() instructions can be used to control
two multiplexers:
AVW200(Data1(),Com1,200,200,mux1(1,1),1,1,16,450,3000,2,_60HZ,1,0)
AVW200(Data2(),Com1,200,200,mux2(1,1),2,1,16,450,3000,2,_60HZ,1,0)
Where,
AVW200 connects to datalogger control ports 1 & 2 via 17855 cable
(option Com1)
Each multiplexer has 16 sensors connected to it.
Begin Frequency = 450
End frequency = 3000
Excitation voltage = 12 V peak to peak (option 2)

A thorough description of the AVW200() instruction and its
parameters is provided in Section 6.1.
Complete example programs that
control two multiplexers are included in Sections 7.2, 7.3, and 7.4.1.

For this example configuration, vibrating wire sensors are attached to
multiplexers, which are controlled by an AVW206.
The AVW206 interface
transmits the data to an RF401 spread spectrum radio that is connected to the
datalogger.
