Abstract:
A system and method for coupling a temperature monitoring system within a progressive cavity pump to combat dry-running. A temperature monitoring system for use in a progressive cavity pump for monitoring the internal temperature of an elastomeric stator. The temperature monitoring system includes a sleeve and a temperature sensor disposed therein. The sleeve is inserted into a shell portion of the stator before vulcanizing the elastomeric stator so that the sleeve is vulcanized to the elastomeric stator.
