CP-044 Diesel clamp on ( fuel injection pipe ) detector

Now includes NABL Calibration Certificate.

The CP‑044 is a rugged clamp-on rotation detector specifically designed for diesel engines. It accurately senses engine RPM by detecting vibration from fuel injection pulsations, making it ideal for use with compatible tachometer instruments..

The CP-044 is engineered for non-invasive diesel engine RPM measurement. By clamping onto the first cylinder’s fuel injector pipe, it uses the mechanical vibration caused by each injection event as the timing signal. The built-in piezoelectric element captures these vibrations and generates an electrical output that can be fed directly into compatible tachometers.

Its heat-resistant cable ensures durability in high-temperature environments such as engine bays. The clamp-and-lock mechanism allows for quick installation and stable attachment during engine operation. Designed for portability and ease of use, the CP-044 is well-suited for both field diagnostics and workshop testing without requiring engine modifications.

  • Purpose-Built for Diesel Engines – Clamps directly onto the fuel injector pipe for precise RPM detection.

  • Piezoelectric Sensing Technology – Detects injection-induced vibrations and converts them into accurate electrical signals.

  • Wide RPM Detection Range – Measures engine speeds from 400 to 6,000 r/min.

  • Heat-Resistant Cable – Equipped with a durable, high-temperature signal cable approximately 4.9 meters long.

  • Secure Clamp Design – Features a quick clamp-on mechanism with locking nut for stable installation.

  • Compact and Lightweight – Easy to handle and install, even in tight engine spaces.
