4" Horseshoe Dynamometer Transducer
Brand: Echometer CompanyThe 4" Horseshoe Dynamometer Transducer is used to accurately measure the polished rod load and position.
The 4" horseshoe transducer is installed between the pumping unit carrier bar and the permanent polished rod clamp. To install the 4" horseshoe transducer a temporary polished rod clamp is positioned on the polished rod about 4 inches above the stuffing box while the polished rod is at the bottom of the stroke.
A temporary knock-off block is located on the stuffing box as the polished rod with the temporarily installed clamp is on the down stroke.
Also on the down stroke, the motor is turned off. The momentum of the system causes the polished rod to continue downward until the temporarily installed polished rod clamp comes in contact with the knock-off assembly.
The pumping unit brake is set when the polished rod is at the bottom of the stroke. This causes the permanently installed polished rod clamp that normally rests on the carrier bar to be several inches above the carrier bar.
The factory calibrated zero offset coefficient is C1. The span is recorded in C2. C6 is the factory calibrated accelerometer sensitivity coefficient. C1 and C6 can be re-calibrated in the field using software instructions.
