Current Clamp Transducer
The
Current Clamp Transducer
allows easy measurement of the
motor current
. Motor Current is
measured throughout the pumping cycle on both the upstroke and the downstroke. This allows easy
viewing and analysis for quick pumping unit balance.
The current transducer is a small handheld device with an opening jaw that is easily clamped around the
power wires in the control panel. To use the current transducer, you do not need to make any changes to
the control panel as some other devices require.
The Sage DYN software displays a motor current plot for quick visual analysis.
String Transducer
The String Transducer monitors the position of the rod string during dynamometer testing. Proper
position data is recorded across the entire range of pumping comfiguration.
The String Transducer installs in seconds, functions properly without perfect alignment, and the string
retracts into the housing for trouble-free operation.
