GTecLink Data loggers
4.1 Vibrating Wire Data Loggers
Sensor connections
4.1.1
Most vibrating wire sensors can be interfaced to the GTecLink VW Data
loggers.
The data logger is supplied with cable glands (one for each channel) to
adjust different cable diameters.
After each terminal block is connected, we recommend taking a sensor
reading in order to ensure that the connections have been carried out
correctly.
This reading should be compared with the sensor reading at installation
with a portable readout u n i t before connecting to the GTecLink data
logger.
Note that some configuration is required during installation.
Cables must be connected in accordance w ith the following table: Each
terminal block has a group of five connectors.
Each group has:
● 1x Vibrating wire channel
● 1x Thermistor channel
● 1 Shield terminal
An example of terminal block connections (Table 1 and Figure 46) can be
found below.
