Abstract
A chain pull analyzer system including a telemetry unit for sensing the strain experienced by the chain while under load and in operation and for transmitting a radio frequency signal proportional to the strain and a data unit for receiving the radio frequency signal transmitted by the telemetry unit and for producing strain data output based on the radio frequency signal. The telemetry unit includes a strain sensing unit for sensing the strain experienced by the chain while under load and in operation and for producing an electrical signal based on the strain, the strain sensing unit including a body member for replacing one of the center links of the chain; a signal conditioning unit for converting the electrical signal produced by the strain sensing unit to an analog signal, the signal conditioning unit including a body member for replacing one of the center links of the chain; a radio frequency transmitter unit for transmitting the analog signal of the signal conditioning unit, the radio frequency transmitter including a body member for replacing one of the center links of the chain; and a source of electrical energy for energizing the strain sensing unit, the signal conditioning unit and the radio frequency transmitter.
