pressure temperature recorder
This device fit inside a machined metal tube to be lowered into natural gas wells with pressures up to 20,000 PSI and temperatures to 150ºC. It recorded pressure with the accuracy of 0.021% F.S. (Full Scale) and resolution of 0.0003% F.S..
I designed it this device with a 24 delta sigma converter. Careful calibration procedure was used to achieve the required accuracy.
I completed the design of the electronics, prepared schematics PCB and completed the firmware for this device.
Field service of a seismic instrument in New Mexico
I assisted on this design of a line of seismic instruments. These devices digitize analog data with 24bit resolution of up to 120channels in a single box. I assisted with the design, troubleshooting and deployment.
With these instruments I got around the world: Minnesota, Oklahoma, Arkansas, Texas, Alberta (Canada) and China. The attached picture is showing field troubleshooting in New Mexico near Chaco Canyon.
This was an amazing experience working with a variety of clients and how things can go wrong in the field.
