COP-trace Coil-on-Plug Signal Probe for oscilloscopes

COP-trace is used for comparative express diagnostics of the ignition system, fuel injectors, electromagnetic valves, and the generator. It is recommended to be used together with the DifAmp signal amplifier. The sensitive element of the probe is applied to the ignition coils and allows for the measurement of key parameters of the secondary voltage, determining the spark's ability to ignite the fuel-air mixture and identifying issues related to high-voltage wires, spark plugs, caps, and coils.

Design

The sensor features an inductive-type sensing element designed to detect the magnetic field generated by the ignition coil. This enables effective diagnostics of most ignition coils, including shielded types. The semi-flexible coaxial cable allows the sensor to be shaped as needed and retain its form during operation. In addition, the sensor’s low-profile design enables use in tight or hard-to-reach areas—for instance, when the intake manifold covers ignition coils.

Since the sensor output signal amplitude reaches up to 100 mV, it is recommended to interface the sensor with the DifAmp50 differential amplifier to ensure adequate signal conditioning.
