vibration wire Piezometer RST


kokihualpa Jul 31, 2017 02:02 AM

Excuseme

have you work with a vibration wire Piezometer RST model VW2100?. I have the adapter AVW200 but Is there any advice respect to him?.

It can connect to the AVW200 or it has a connector special or has cables for communication analog?

thank you

Take a look at Section 8.1.2 in the CRVW3 manual (starts on page 18)

http://s.campbellsci.com/documents/us/manuals/crvw3.pdf

In your sensor manual, you should be able to find out whether your sensor has

a built-in thermistor or not. If you have a thermistor, there will be 5 wires on the

sensor - Two of them are for the coil ("VW") and two are for the thermistor ("T"),

and then there is the shield/ground. If your sensor does not have a built-in thermistor,

then you will have three leads. Two of them are for the coil ("VW") and then there is the

shield/ground.

From the CRVW3 manual:

A vibrating-wire sensor may contain a built-in thermistor or other resistive temperature measurement device. If so, it will have five wire leads. Sensors without built-in temperature monitoring have only three leads. Refer to the sensor manufacturer’s documentation to determine what sensor type you have.CRVW3 3-Channel Vibrating-Wire Datalogger19FIGURE 8-1. Wiring Panel of the CRVW3 Two of the sensor leads are for the main vibrating-wire measurement, and they are wired internally to the coil-circuit of the sensor. This connection is used for both sensor excitation (energy input) and for reading out the current measurement (measurement output). These two leads should be connected to the two VW terminals on the CRVW3 corresponding to the desired measurement channel. The shield wire should be connected to the ground associated with that channel (located in between the VW terminals and the Tterminals). If the sensor has a built-in temperature measurement device, those two leads should be connected to the two T terminals.Sensor manufacturers often color-code the leads so you can easily identify which leads are for the coil-circuit and which are for the temperature device. Polarity does not need to be considered when wiring the two leads for the VW terminals and the two leads for the T terminals.
