Electronic equipment is available for installation on electric motor driven beam pumping units which provides load and displacement data for a complete well analysis including rod stress, gearbox torque and downhole pump card calculations. The electronic equipment also monitors the load and displacement and shuts the well down for a predetermined amount of time when a pumped-off condition occurs and also shuts the well down and sets an alarm when a rod part is detected. When well data is needed for analysis the load and displacement data can be plotted on a dynamometer and at the same time the load and displacement data is recorded on an electronic memory card for replay into a computer. The electronic memory card records one full cycle of the pumping unit in equal time increments for use in gearbox torque and downhole pump card calculations.
