STELZNER® agricultural measurement systems

Measuring instruments for soil moisture and water monitoring, using sensors, tensiometers and data loggers

Bambach – TensioLogger

Data logger for tensiometers and volume sensors

All-purpose data logger with bus-mode operation and modular design for up to 100 measurement commands (approx. 50 to 100 sensors), with local read-out or with remote transmission via mobile wireless/GSM.

The corresponding digital sensors are connected via the RS485 interface (T-bus) (volume sensors, refer to page 44). The data logger housing has four plug-in slots for max. eight sensors. Additional sensors can be connected via external connection boxes with corresponding addresses.
Analogue sensors (tensiometers etc.) can also be integrated using a box with an analogue-digital interface. Several connection boxes can be connected in series using plugs. The data logger can also be removed on its own for a read-out.

The USB cable interface is used for direct read-outs and for configuring the data logger. The built-in battery pack can be used to supply power. For more stationary use, a mains connection or a solar module is also possible.
