An apparatus for detecting and transmitting impact data is disclosed for use in monitoring early-stage development of harmful mechanical conditions for reciprocating machinery. The impact transmitter device includes a single self-contained unit having a stainless steel housing which contains an impact accelerometer, a detector circuit, a measurement and timing circuit, a 4-20 mA driver circuit, independent polarity circuit, and an electromagnetic impulse protection unit. The impact transmitter device further includes a field adjustable static threshold defining the severity of the impact detected, and a field adjustable reference time window interval. The variable severe impact level threshold allows an operator to isolate severe impacts from typical machine vibration. The variable time window interval allows an operator to synchronize the present invention with different machine speeds and to collect severe impact data over an appropriate time frame. Additionally, the impact transmitter device provides functionality independent of the polarity of the power of a programmable logic controller or distributed control system.
