Emerson introduces rugged, high precision digital downhole data logger

Downhole drilling operators must measure pressure and temperature to optimise drilling processes and ensure safety. These measurements are typically made with a variety of downhole tools, either mounted just above the drill bit to provide continuous measurement while drilling, or as separate tools inserted into the drill hole on a periodic basis. Once drilling is complete and production begins, these measurements are needed to optimise throughput, maximise uptime, and ensure safety.

In all of these applications, space is at a premium and high reliability is required. The environment is extremely harsh with high temperatures and pressures, corrosive drilling fluids, and high vibration. Rugged components with small form factors are required to support smaller tool sizes, along with increased pressures and temperatures as holes become deeper.

To address these issues, the Paine 328-12-0010 data logger/transmitter provides both temperature and pressure measurements in a small, rugged form factor. The transmitter measures pressure and temperature with full-scale accuracy of ±0.05% and is able to withstand operating temperatures from -40°F (-40°C) to 347°F (175°C). The slim-diameter form factor of 0.51 in. saves critical downhole tool space.

Measured data can be transmitted via the built-in RS-485 digital data link. Using on-board memory, the device also provides data logging functionality, allowing it to automatically store large amounts of data for future analysis.
