The signal is collected from the hydraulic system of the rig and converted into torque units. In case of an electric driven motor for the turntable the electric current for the motor is used as signal for the torque.
Various sensors are available for receiving of optimal signals. The menu-guided software of GEOCOMP-3 makes the adaptation to all calibration requirements possible.
The torque is recorded on the time base printer (standard). From DATA TERMINAL torque can be printed any time versus depth too.
GEOCOMP-3 displays the actual torque at any time required.
The rotation per minute (RPM) of the rotary table is picked up from pulses produced by the gears towards a touch less- sensor. Any kind of teeth from the drive can be used for detecting the needed pulses for one rotation.
The sensors are magnet operated reed-contact sensors or proximity types or Namur types. That means only mechanical destruction may stop them to work.
The result is displayed on GEOCOMP-3 and of course visualized on DATA TERMINAL.
