Polished Rod / Horseshoe Dynamometer System



Product Number

EQ1060 / EQ1160

The Polished Rod/Horseshoe Dynamometer System is designed for acquisition and interpretation of:

  • Dynamometer measurements using either the Horseshoe Transducer or the PRT.
  • Electric motor current measurement and analysis simultaneous with dynamometer.

The following summarizes the system configuration and products included in this package:

Additional Information

The Horseshoe Transducer is a high accuracy ( 0.1%) load and position sensor. It is rated to 30 KLb. Used with the TWM software, it allows troubleshooting the pumping system when abnormal operation is detected using the PRT. It is also recommended to be used when the majority of the wells to be tested are very shallow and have small diameter pumps.

The Polished Rod Transducer (PRT) is designed for easy and safe installation and permits the operator to quickly obtain surface dynamometer cards, pump cards and standing and traveling valve tests. Its use is generally preferred by most operators and yields accurate measurements in the majority of the cases.

All load cells contain an accelerometer for determination of position.  The accelerometer is a more accurate and reliable technique for determining acceleration, velocity and position.   Acquiring and processing acceleration data is a more convenient, accurate and reliable technique for determining polished rod position than utilizing the troublesome string-type potentiometer.
