Full bridge signal connection
6-wire and 4-wire sensor connection
Voltage or Current excitation are allowed.
Sense lines MUST be connected to the excitation also when 4-wire connection is used.
6-wire sensor connection: Sense+ is connected to EXC+ at the sensor
4-wire sensor connection: Sense+ is connected to EXC+ at the connector
Half bridge signal connection
5-wire and 3-wire sensor connection, and potentiometric sensors
5-wire sensor connection: Sense+ is connected to EXC+ at the sensor
3-wire sensor connection: Sense+ is connected to EXC+ at the connector
Voltage or Current excitation are allowed.
A potentiometer can be seen similar to a half bridge sensor with ±500 mV/V sensitivity. Therefore poten-
tiometric sensors can be measured with bridge ampliers. The advantages of using the MDAQ-STG for
potentiometric measurements is by adjusting the offset and range, you can focus on a certain potentiometer
position with higher resolution. The scaling is ±500 mV/V equals ±50 % of potentiometer position.
