Claim:
1. A load cell for transmitting load data of a polished rod in a rod pump system having a rod clamp fixed to a top of the polished rod and a clamping bar fixed to a hanger harness attached to a horsehead, the load cell comprising: an outer shell including a u-shaped structure having two protrusions, the u-shaped structure configured to receive the polished rod, and the outer shell configured to be positioned between the rod clamp and the clamping bar of the rod pump system; a load sensor configured to receive a voltage and output a load signal based on a load experienced by the load sensor; a load signal processor configured to receive and process the load signal from the load sensor and to output load signal data representative of the load experienced by the load sensor, wherein the load signal processor is internal to the outer shell of the load cell; a modulator configured to receive the load signal data from the load signal processor, to modulate the load signal data, and to output the modulated load signal data, wherein the modulator is internal to the outer shell of the load cell; a wireless transmitter configured to receive the modulated load signal data from the modulator and to wirelessly transmit the modulated load signal data; a solar battery configured to provide power to the load cell, the solar battery including: wherein the solar battery is configured to provide the voltage to the load sensor.
