Load cell boosts performance levels
31/08/2018
LORD Sensing/Stellar Technology has introduced a pump-off control (POC) load cell, which it claims will provide improved performance and reliability when compared to existing offerings currently used in the oil production industry. The Series CTH932 POC Load Cell was designed specifically to meet the industry’s need for a more reliable and durable means of measuring polished rod loads in production wells. The new state-of-the-art design extends usability and enables customers to enhance their control system capability to perform tasks such as prognostic health monitoring and maintenance.Designed for an extended cycle life (50,000,000 cycles), the high-durability stainless steel hermetic internal connector and cable exit design reduces cable fatigue with cyclic motion of the sucker-rod. In addition, the system offers more reliability in the field and a more robust mechanical package, ensuring the system can withstand severe environmental, electromagnetic interface and power disturbances.
Features include:
- The ability to resist off-axis loading for more accurate direct measurement of pump load;
- Improved static accuracy of 0.25% full-scale output, resulting in better prediction of pump maintenance and more reliable production operation; and
- Stainless steel, fully-welded hermetic construction, in a shock- and vibration-resistant design for superior environmental protection.
