		DM-602/604 Ultrasonic Drilling Monitor for Construction


	KODEN promotes intelligent foundation work.


	Recorder Unit


	Deeper Excavation measurement in high accuracy Clear recording even in slurry contaminated with dirt and sand High quality excavation work reducing time and cost

Recent progress and development in foundation engineering has resulted in great strides in excavation techniques. By using artificial slurry of high density and specific gravity, deeper excavation has been made possible. The DM-602/604 series Drilling Monitor system has been developed in compliance with user's needs arisen from the recent construction environment to accurately measure and record the shape of a drilled hole of greater depth. It can be easily positioned and se up for measurement to provide quick and accurate recordings of excavations. The DM-602/604 series Drilling Monitor provides the following advantages.

Helps improve the quality of a drilled hole and reduces working time and cost.

Provides on site records of the perpendicularity of drilled holes and the shape of Cross sections in high accuracy.

Provides numerical measurement data that can be easily imported into various Windows applications (Excel, Word, Power Point, etc.) for work reports, etc. (Option)

FEATURES

The DM-602/604 supplies clear records of a drilled hole even in slurry, heavily contaminated with dirt and sand.

The DM-602/604 supplies clear and precise records thanks to its unique signal processing technique that discriminates wall echoes from the noise.

The DM-602/604 has the facility to cancel the oscillation line echo that often prevents very close echo recording.

The sensor device is automatically controlled to stop at the casing and at the bottom of the hold. An emergency return function is also included.

Depth range mark, depth mark, drilled hole mark, date, time, etc. can be printed on the recording paper.

Limit switches are provided to avoid possible wire breakage or entanglement of the wire and cable.

The recorded result can be output to an external PC via a built-in RS-232C output port. (Option)

A non-fuse circuit breaker is used for circuit protection, eliminating the need for cumbersome fuse replacement at the construction site.
