8.3.3 Tensiometer loggers

All SWT Tensiometers can be connected directly and without further
power supply to the special Tensiometer logger DL6-tens.
Accessories are available for converting GP1 and DL2e loggers to take
Tensiometer readings.
DL6-tens Logger
The DL6-tens can take six SWT Tensiometers.
This is a factory-modified Delta-T DL6 6-
channel logger with six 4-pin M12 sockets.
Each Tensiometer needs a
SWTEC-20 extension cable.
GP1 Logger
A GP1 logger can take two SWT
Tensiometers. Each tensiometer requires a
GP1-PBA1 adapter and connection cables
type SWTCC-XX .
In addition 2 SM200 soil moisture sensors,
(or 10K thermistors), and a WET sensor may
also be connected at the same time, along
with two digital sensors such as rain gauges.
When fitting 5 or more sensors use the
GP1-LID2 expansion lid which has additional
cable glands.
DL2e Logger
Up to 60 SWT tensiometers may be connected
to a single DL2e.
Each group of 15 Tensiometers require one
LAC1 input card and one TVB1 voltage
regulator.
