Abstract
An inspection sensor module for an in-line pipe inspection tool has a support for mounting the module on the tool, a finger pivotally attached at one end to the support and pivotally attached at the other end to a sensor block carrying one or more inspection sensors. A first leaf spring extends from the support to the finger to bias the finger outwardly, and a second leaf spring extends from the support to the carrier to bias the sensor block. Biasing sensors are mounted on the leading and trailing edges of the first leaf spring to detect movement of the first leaf spring corresponding to movement of the inspection sensors towards or away from the support.
