The AEINSTRON ERSENS-25K/ERSENS-27K is a Clamp-On electromagnetic inductive sensor designed for making RPM measurements on gasoline engines. The sensor will detect the high voltage flux field being induced from ignition coils on 2 or 4 cycle gasoline engines. The ERSENS-25K is supplied with amplifier module, which provides input power for sensor and outputs a Square Wave pulse having amplitude equal to Supply voltage. The ERSENS-25K includes an integral 2.0 m cable & amplifier module has a 3.0 m shielded cable with 3 tinned wires for termination. Inbuilt display version is also available for diagnostic purpose & verification of logged data.
The ERSENS-25K / 27K is connected to the Aeinstron amplifier module , The amplifier module can be directly interfaced with your Data acquisition system / Vehicle Data Logger or Combustion Analyzer.
