An indicator apparatus has multiple stages to effectively handle data processing, particularly raw data from a mechanical load cell, such as those used to monitor loads in the mechanical workings of a torque arm reducer. Processing of such raw data is split into parallel operations relating to both signal level and signal polarity functions. This multi-staged approach enables increased precision as to both functions due to tailoring of the data inputs to different stages. Use of staged circuitry to effect the separated functions also readily permits the presence of an unobtrusive monitor level signal output. Combined with other features, a limit detector and alarm permits accurate provision of both a stable response to low frequency steady state mechanical data and to fast-acting high frequency transient/dynamic data contained therein. Indicated polarity changes signify alternating tension and compression in the mechanical couplings of a load cell.
