Abstract
Official abstract text for this publication.
A sensing indicator for a downhole tool, the sensing indicator includes a sensing mechanism including a sensing device and an RFID tag. Wherein the RFID tag is only readable when a set limit is exceeded. The set limit related to a sensed condition of a downhole component of the downhole tool; and, a housing supporting the sensing mechanism. The housing protecting the sensing mechanism from downhole conditions. Further is method of indicating whether a sensed condition of a downhole component in a downhole tool has exceeded a set limit
First claim
Opening claim text (preview).
What is claimed: 1. A sensing indicator for a downhole tool, the sensing indicator comprising: a sensing mechanism including a sensing device, a radiofrequency identification tag, and a switch, the sensing device arranged to sense a sensed condition of a downhole component of the downhole tool, the sensed condition including at least one of a temperature, pressure, and strain condition, wherein the radiofrequency identification tag is unreadable before the sensed condition exceeds…
