3DM-DH3

Discontinued
The 3DM®-DH3 is a downhole orientation sensor and datalogger. It incorporates acceleration sensors, magnetic field sensors, and temperature sensors, together with an on-board microprocessor, embedded software algorithm, non-volatile memory for configuration, flash datalogging memory, and serial communication interface. Its form-factor, rated temperature range and power supply requirements are optimized for downhole applications.

The 3DM-DH3 provides accurate drill path measurements including Inclination, Azimuth, GTF, MTF, Dip Angle, sensor temperatures, G-TOT and H-TOT.

The 3DM-DH3 is operated by a combination RS-422 communication and power cable, part number 4005-0003.

 

 

Yes.  The unit is factory calibrated and ready for use with power-up.

Physically, the 3DM-DH3 is easily mounted into the drill string using its body’s threading attachments. It can be tethered to an RS-422 communication cable for continuous real-time measurements to a host computer during drilling operations, or it can be remotely deployed and run as a datalogger, with data retrieval after it has been run through the drill path. The unit can be powered through the communication cable tether from a platform source or by batteries.

The 3DM-DH3 has measurment accuracy of +/-0.2 degrees inclination and +/-0.5 degrees azimuth.

The 3DM-DH3 has a four-wire full-duplex RS-422 serial communication interface.

Yes.  A Windows XP/Vista/7 compatible software is shipped the product.  The software allows the user to configure, operate, display and save data from the sensor.

The 3DM-DH3 will operate within a temperature range of - 40 degrees C to 125 degrees C.

The 3DM-DH3 provides accurate drill path measurements including Inclination, Azimuth, GTF, MTF, Dip Angle, sensor temperatures, G-TOT and H-TOT.
