Position Monitor
Primarily used for negative pulse services.
Electronics built into a 2” O.D. pressure case.
Internal calibration done in Houston only.
Calibrated for a range of temperatures.
Dumb sensor – calibration factors have to manually stored in INSITE.
Requires a internal pressure transducer to determine pumps on/pumps off conditions.
Quartz hinged accelerometers.

Directional Module
Primarily used for positive pulse services.
Also replacing the Position Monitor (PM) in negative pulse.
Electronics built into a 2” O.D. pressure case.
Internal calibration done in Houston only.
Normally used as a hot hole tool (Solar 175).
1553 Serial Manchester communications only.
Kemlon connectors found on both ends.
Serial No. and Part No. always indicate top of tool.
High side tool face found on the bottom (alignment hole).
CAUTION: USING THE WRONG POSITION CAN TURN INCLINATION FROM 0° TO 180°.

4 Stage Evolution:
Pressure Case DEP II (PCD)
Pressure Case DEP II – Kemlon (PCD K)
Pressure Case DEP II – Ruggedized (PCD R)
PCD-C
All types have electronics built into a 1-3/4” pressure case.
Interfaces with FEWD tools
Custom Data String (CDS) Capability, MEP Mode, GAM Mode, EMT Mode, MGT Mode.
PCD
10-pin amphenol connector on top
7-pin amphenol connector on bottom
High side tool face found on bottom (flat area).

Pressure Case DEP II
PCD-K
10-pin amphenol connector on top, kemlon connector on bottom.
Allows Manchester 1553 communications to FE tools i.e. EWR-P4, CNP …
Problems were encountered with cracked kemlon connectors.
PCD-R
Same type of connector setup as with the PCD K.
Kemlon boot was re-designed.
PCD-C
Kemlon boot on both sides

Directional Electronic Probe
2 Stage Evolution:
Directional Electronic Probe (DEP)
Directional Electronic Probe II (DEP II)
All tools require manual insertion into a 1-3/4” sensor pressure case.
From this point onwards, all directional modes were electronically switched using a surface computer.
DEP
7 pin amphenol connector on top.
High side tool face found on bottom (T-slot) which indicates Gx position.
Option available to take pumps-off survey by adding a lithium battery on upper housing.

Directional Electronic Probe
DEP II
10-pin amphenol connector on top, 7-pin amphenol connector on bottom.
Bottom coil cord connected to a brass crossover and kemlon connector.
Lithium battery replaced with Manchester 1553 communications board.
Allowed capability to attached FE tools if required.
Currently being phased out and replaced with PCD-R.
Custom Data String (CDS) Capability, MEP Mode, GAM Mode, EMT Mode, MGT Mode.
