to measure such a signal level, but many loggers cannot do this.
In this case use a TV-batt power supply.

TV-batt Tensiometer power supply

The TV-batt power supply is specially designed for Tensiometers T3,
T4, T4e and T5. It offers a stabilized 10,6 V power supply, but with
supply minus = -5 V and supply plus = +5,6 V. Therefore the output
signal will have a logger specific signal level. The Tensiometer
signals are in a range of <1 V.
The TV-batt is directly supplied by battery or 12 V mains power.

Connection to a data logger

Some logger types can measure bridge circuits directly, other
loggers require certain measures as the Tensiometer signal minus
and the supply minus do not have the same ground.

Tensiometer loggers DL6-te or GP1-te

T5 and T5x can be connected directly and without further power
supply to the special Tensiometer loggers DL6-te or GP1-te.
