depth sensor
(OP)
I am interested to measure well depth with a drill bit and to string the sensor through drilling stems to a computer?

RE: depth sensor
In such cases, most would probably just keep track of the number / length of the drill stack. My well driller knew the drill depth by looking at his truck to count the number of shafts in use, and then looked at the rig for the last fraction.
You'll probably need to provide more details.
RE: depth sensor
Thanks, the hole is actually a shallow (shot) hole for land seismic acquisition, it has been an issue with my crew for the drillers has been reporting fictitious values.
So, i am looking for a way to control such occurrences.

Call me crazy, but employees who can't be honest about the work they perform don't deserve to be employed.

RE: depth sensor
Yes, you are right.
But, this is not what you can discover real time or close to real time, because it takes some days between drilling and recording.
The true depth is important for accurate statics correction.
RE: depth sensor
Bit of a rant, but I see employers willing to ignore the problem employees more and more these days, even to the detriment of the operation as a whole. Short sighted, IMO.

A more impractical solution would be an acoustic sonar to fire down the hole (assuming dry) and record GPS location and time & date, and the measured distance (depth). Post drilling of course.
Good luck.

There are scads of DVRs specifically designed to be used in vehicles with DC power inputs. Start with ebay.
