Beschreibung
Zusammenfassung:	An inflatable packer assembly (202) that includes opposing end fittings (211) by which the inflatable packer assembly is installable within a downhole tool string (108). An inflatable body (210) coupled between the end fittings (211) has an external groove (214). An elongation sensor (216) is fixed in the external groove (214). The elongation sensor (214) includes a capacitive element that whose capacitance varies based on elongation of the elongation sensor in response to inflation of the inflatable body (210).
