ABSTRACT:
Methods and apparatuses, in one aspect, for detecting and indicating loads and/or forces on tubular strings, e.g. tubing, injected into or withdrawn out of a well by an injector apparatus, the apparatus having, in one embodiment, a single piston acting on a single boot with a chamber therein having a fluid the compression of which in response to a load or a change in load is sensed to indicate the load on the apparatus; the indicator in one embodiment having a spring to add to the weight of the injector apparatus to provide a positive pre-load so that negative loads can be determined by a change in positive pressure without requiring negative pressure; and a pressure chamber device for use with such apparatuses and in such methods.
