The WPS500X Pressure Transducer

View, understand and diagnose vehicle pressure systems like never before!

The WPS500X features an extremely fast, 100 µs, response time from 0% to 90% of full scale, and sensitivity down to about 0.07 psi (5 mbar). This provides you with an accurate representation of rapidly changing signals that span a broad pressure range.

Use the WPS500X with PicoScope to have a detailed insight into the engine system and reveal how your engine is actually performing with minimal intrusion. Compression, airflow, valve timing and back pressure can all be measured in one hit, giving you information that can help in solving common problems like:

  • no start
  • loss of power
  • misfire
  • stalling
  • engine noise
  • emissions fault
  • backfire

The WPS500X Pressure Transducer has:

  • accurate measurements up to 500 psi (34 bar)
  • ultra-fast, 100 µs, response time
  • zoom function for enhanced analysis capabilities
  • an internal, rechargeable LiPo battery
  • integrated pressure relief / bleed-off valve
  • auto-zeroing
  • high noise immunity
  • temperature compensation

Some of the tests you can perform with the WPS500X Pressure Transducer

In-cylinder compression testing:

Connect PicoScope by removing a spark plug and installing the WPS500X Kit. The high level of detail in the captured compression waveform provides you with the information you need to confidently diagnose the cause of compression issues. You can also test compression on diesel engines using our diesel glow plug adaptor set. Please refer to our software guided test for further information about how to perform these checks.

Injector back-leakage testing:

For low-pressure return systems, you can use the WPS500X Pressure Transducer to evaluate each diesel injector’s contribution to back-leakage pressure.

When you combine it with a current clamp, you can quickly diagnose issues with irregularities attributed to injector malfunction.

Low fuel pressure testing:

By using a PicoScope and the WPS500X with the Pico Sight block kit, you can verify the integrity of low-pressure fuel systems. We can look at priming pressure, low pressure associated with priming pumps in tank, fuel filter blockages, leaking pipes hoses or injectors, and aeration within the fuel system.

The WPS500X Pressure Transducer is part of multiple Pico kits and has a line of its own accessories that gives you the tools you need to test a range of pressure components.
