US 2019/0355945 A1 · SENSOR SUB CONFIGURATION

Abstract

A sensor sub is provided for use in a tubular handling system, the sensor sub being located adjacent to and removably connected to a saver sub pin connection. The sensor sub collects raw data relating to operation of the tubular handling system, digitizes the raw data and transmits the raw data to a remote receiver. The sensor sub is powerable by one or more commercially available lithium batteries. A battery holder is also provided having a housing for housing batteries in a hazardous environment, wherein the batteries are replaceable within the battery holder while the battery holder remains in the hazardous environment. Finally, a method of replacing a battery in a hazardous environment is also provided.
