TDR Waveguides

Waveguide Connector

The Waveguide Connector, which is included in the System I, provides a sturdy, flexible method of inserting waveguides into the soil. Turning the knurled handle locks and unlocks the waveguides in the connector, enabling the waveguides to be interchanged quickly and easily. This allows multiple measurements, with waveguides of different lengths, to be made rapidly. The waveguides can also be installed permanently in the soil so that periodic measurements can be made in the same location by simply attaching the connector to the waveguides, without disturbing the soil by repeated insertions of the waveguides. An Alignment Block is available which helps maintain the proper waveguide spacing during installation, especially helpful when inserting longer waveguides. Waveguides, ordered separately, are available in lengths ranging from 15 cm to 70 cm.

Buriable Waveguide

The Buriable Waveguide is designed to be installed permanently in the soil, and allows measurements to be made at any depth in the soil profile. The waveguide rods are 20 cm long and made of 1/8" (0.3 cm) diameter stainless steel rods. The Buriable Waveguide can also be used portably in light-duty applications and where space is limited. Extension cables of various lengths are available, allowing multiple waveguides to be connected and controlled from a central location.

Coated Buriable Waveguide The Coated Buriable Waveguide is designed for use where salinity or the presence of chemicals in the soil may make it difficult to make accurate measurements. The central waveguide rod is coated with a special plastic which reduces signal loss and allows measurement under difficult situations.
Slammer The Slammer is a heavy-duty waveguide connector designed for rugged field use. It is designed for inserting waveguides into hard, dry, and compacted soils, and for comfort and ease in making multiple measurements. The removable 2.5 lb sliding hammer can be used to insert waveguides under the most difficult of conditions. Waveguides, ordered separately, are available in lengths ranging from 20 cm to 60 cm.
Borehole Connector A heavy-duty waveguide connector, similar to the Slammer, but without the T-handle. The Borehole Connector has a threaded coupling, allowing standard 1-inch threaded pipe to be screwed into the head to guide the probe down a borehole. Standard 3-inch pipe can be used as a drop hammer to drive the probe into the soil. Cable length must be specified at the time of order.
Mini Buriable Waveguide The Mini-Buriable Waveguide is designed for use in making near-surface shallow measurements, and in laboratory column studies. The rods are 8 cm long, with a 2.5 cm spacing between the outer rods.
