Lysimetertensiometer Tensio 160

Tensiometers serve the determination of the soil moisture.

The determination of the soil moisture tension (Tension) of the soil is carried out by means of a ceramic cell.

The Pressure sensor is temperature and pressure dependent calibrated with storage of sensor identification and calibration data.

The Pressure sensor provide an optimal combination of ease of use of mobile Feldtensiometer with the electronic data capture. As with the Tensio 100 Feldtensiometern the measuring system from a V2A standpipe (Ø 10 mm) and stainless steel-tip, and a brass-supporting body and a ceramic cell (SKA 100 FF, 10x24 mm). The detection of the suction pressure via a highly sensitive pressure transducer in light metal tensiometer head (IP65). A signal amplifier in the tensiometer head and shielded cables allow interference-free transmission of data over long distances. The standard cable length is 5 m.

The Tensio 160 is designed for long-term use in lysimeters and specifically designed for horizontal mounting. The arrangement of the filling lines allows the filling and venting in the horizontal state, so that the tensiometer does not have to be developed for this purpose. In combination with appropriate optional electronic control system, the filling can be fully automated to achieve a minimum of maintenance. The pressure sensor with stainless steel diaphragm ensures optimum performance and durability. If required, the sensor can be replaced without removing the tensiometer.

The device consists of:

• Light metal tensiometer head (IP65) protected with integrated 2-channel sensor MicroBrain (IMP bus interface)
• high-resolution imaging transducer,
• PT100 temperature sensor,
• Acrylic glass refills facility coupled to ceramic candle (P80, 20 × 50),
• PVC standpipe (20 mm) and
• 5 m connection cable.

Following standpipe lengths are available: 30, 60, 90, 100,200 and 300 cm.

The main features of Lysimetertensiometer Tensio 160 are:

• Good value for money,
• stationary soil moisture measurements,
• long-term stability,
• high accuracy through the use of special ceramics,
• low-maintenance operation,
• easy handling
