Abstract
A sensor system includes interconnected and axially spaced apart sensor devices deployed along an outer surface of a downhole tool string. The sensor devices including a sensor disposed with a protective housing and control electronics located remote from the sensor devices and operationally connected to the sensors.
Claims13
A sensor system, comprising:
- sensor devices interconnected and spaced axially apart along the outside surface of a perforating gun string disposed in a wellbore, each of the sensor devices comprising:
- a protective housing having shock mitigation packaging;
- and
- a sensor connected to sensor electronics, each of which are disposed within the protective housing;
- and
- master electronics located along the perforating gun string and remote from the sensor devices and operationally connected to the sensor devices.

A downhole sensor system, comprising:
- a sensor device comprising local sensor electronics disposed in a protective housing, the sensor device disposed along the outside surface of a perforating gun string in a wellbore;
- shock mitigation packaging within the protective housing;
- sensors spaced axially apart and disposed within a protective tubing, the protective tubing extending along the outer surface of gun sections of the perforating gun string, the sensors connected to the local sensor electronics;
- and
- master electronics located along perforating gun string and remote from the sensor device and operationally connected to the local sensor electronics.
