 APRIL 2013

Sunnyvale, California - Applied Physics Systems, Inc. Announces Discontinuation of
the Model 750 Directional Sensor

As of April 1, 2012, Applied Physics Systems will no longer accept orders for Model 750
and Model 850 Directional Sensors rated to 150 deg. C and below.
This action is being taken because certain parts critical to this type of sensor will no longer
be available to Applied Physics Systems. Model 750HT and Model 850HT directional sensors,
which are rated to 175 deg. C, will not be affected by this change.

APRIL 2013

Sunnyvale, California - Applied Physics Systems, Inc. Announces Availability of
the Model 760 Directional Sensor

Applied Physics Systems announces the April 1 release of the newly designed Model
760 Directional Sensor. The Model 760 is intended to replace all existing Model 750
series directional sensors rated at 150 deg. C or below, which are being discontinued and
taken out of production once all current obligations are fulfilled.

Model 760 Product Enhancements

The Model 760 directional sensor is 100% compatible with existing Model 750 units, and
has the following improvements and new features:

  • More rugged sensor package
  • More rugged chassis with Max Temperature Indicator
  • Accurate inclination while rotationg (at 20 deg. inclination or greater)
  • Accurate azimuth while rotating
  • Real-time clock
  • Real-time rotation detection
  • Accurate RPM detection from static to 400 RPM
  • Full logging and device history
  • Windows-based customer log download program with variables for Max Temperature,
    Max Vibration and Max Shock
  • Absolute and resettable counters for operational hours



APS has expanded into its new, state-of-the-art production facilities in Sunnyvale, California.
Our new address is 281 East Java Drive, Sunnyvale, CA 94089 USA



Applied Physics Systems has begun field tests in North America of our new Model 600
Near Bit Sub. Designed to be run with the AP-250 EM MWD System, the Model 600
comes in 5” and 6.5” sizes, both with a length of 36”. On-board sensor and electronics
packages provide inclination, azimuthal gamma, vibration, and rotation data, all transmitted
wirelessly to the AP-250 EM MWD System located above the power section of the BHA
where it is then transmitted to the operator on the surface via EM telemetry.  

Field testing is expected to last 30-60 days with a commercial product release to follow
upon successful completion.
