Abstract
A load cell system for measuring rod load in a pumpjack. The system includes a tension load cell operatively coupled to a bridle between first and second bridle cables at a location longitudinally spaced between a horsehead and a bridle plate of the pumpjack. The bridle plate is coupled to the first bridle cable at a first connection point and the tension load cell is coupled to the first bridle cable at a second connection point longitudinally spaced between the bridle plate and the horsehead. The load cell system defines a third connection point longitudinally spaced between the second connection point and the horsehead. The load cell system is configured to maintain substantially constant longitudinal distances between the second connection point and each of the first and third connection points during operation of the horsehead. The load cell system is further configured to maintain a substantially constant lateral distance between the first and second bridle cables at the third connection point during operation of the horsehead.
