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

Bambach – Electronic tensiometers

E-sensors are electronic pressure sensors for tensiometers that record the continuous negative pressure and thus also the suction tension of the soil or substrate. The sensors require a power supply and are designed with an analogue current output (4 – 20mA) or analogue voltage output (0.3 – 3.0 VDC), depending on the application. The pressure sensor is housed in a ventilated plastic enclosure with encapsulated electronics. In the application, the E-sensors are connected to digital units such as data loggers, switching gear with analogue input, PLC (TensioController), and radio units.

The E-sensors always consist of the pressure sensor and the tensiometer lower part, depending on the desired size or insertion depth. The sensor alone only shows the measured value for the zero point without the suction voltage.

Bambach-BLUMAT plug-in tensiometer

A tensiometer is used to measure suction tension. The porous cell of the tensiometer uses capillary action to transport water outwards into the drier soil. A negative pressure is then created within the closed pipe. This negative... ...more Topseller
