Description

This circuit board is a two channel module that detects a slope change on an analog signal and captures this value as a voltage. The unit is jumper configurable to detect positive slopes or negative slopes. External inputs put the unit in to “track” mode which causes the output to follow the input. When a slope change has been detected a “have peak” signal is available as an output.

This unit is primarily used to detect the valve opening pressure of an injector nozzle group, but has been used to detect peak injection pressure as well as peak rail pressure in a common rail fuel system. The unit can be mounted on 4” snap trak or it can be panel mounted in a case. Since most injector machines take advantage of the timing module as well, both units can co-exist in the same case.
