5. Petroleum technology Pressure Sensor © 2012, all rights reserved info@oginatec.com Surface Deployment Sensor is connected to pressure line using adapter OT-000010 (ring) Ring held in place by Autoclave 1/4 OD tubing Can then be connected to other pressure connection types : Autoclave, Swagelok, NPT, WECO union,... As a recorder Job is configured using PC, then the sensor is disconnected and performs the measurement as a stand-alone recorder As a live measurement Job is configured using PC, and sensor performs measurement while still connected to the PC through a coaxial cable Autoclave end connection. Change to suit your pressure line connection type. Sensor connected to a multiline adapter Example of pump truck line autoclave connection Well-head with Frac lines

There is a room that is taken into sandwitch between the gauge and mandrel which seals with a metal to metal contact. The mandrel (tube on which the gauge is attached) must be designed and manufactured according to customer specifications (diameter production casing diameter, type of steel, thread type).
