RPT-5 Rail Pressure Tester

The RPT-5 device is used for performing an independent, parallel pressure measurement in storage fuel systems such as Common Rail (Diesel) and GDI/FSI (petrol). The tester, apart from pressure value, also diagnoses power supply of a sensor. Additional advantage is the capability of automatically detecting the terminals of the sensor, which is useful especially when using needle probes.

The device can be used to test injection systems of:

  • passenger cars,
  • trucks and buses,
  • tractors and agricultural machinery,
  • construction machines,
  • electric power generators.

  • tractors and agricultural machinery,
  • construction machines,
  • electric power generators.

Not only does the tester allow to read the pressure value, but also to register the pressure waveforms in two modes:

  • Pressure trend – slow-changing pressure waveform that shows the reaction of the system to changing operational conditions,
  • Pressure pulsation – fast-changing waveform that shows fast pressure fluctuations connected with the operation of injectors and CR pump.

In addition, you can download an Android app that lets you remotely read the measured values. In this way you are able to look at waveforms in higher resolution and can save and later read data on a mobile device.

In the case of slow-changing waveforms (100 samples/s) it is possible to register continuous waveforms even for a dozen or more minutes, which provides unique diagnostic capabilities.

To fully check the sensor readings on a rail, we offer an optional cable of an external sensor for a chosen system. It allows to perform measurements with an additional sensor (an own sensor with hydraulic connector is required). An additional external sensor is powered by the tester and operates completely independently. You can carry out with it all the measurements; you can also use a comparison mode that allows to simultaneously read readings from both sensors.

Technical parameters:

  • Voltage measurement: 0..7V
  • Accuracy of measurement: 1%
  • External sensor power supply (option): 5V DC, 50mA
  • Power supply: built-in Li-ion battery
  • Operating time: approx. 8 hours after full charge

Contents of the kit:

  • The RPT-5 device
  • Connecting cable
  • Adapter for the Bosch system – type 1
  • Adapter for the Delphi system
  • Universal adapter – needle probes
  • Mini USB cable
  • 5V charger

RPT-5 – FAQ

 

Where can I find the RPT-5 application for my phone / tablet?

Only the Android app is available. The application can be downloaded after prior registration and logging in to our website: https://dte.com.pl/en/my-data/.

 

Which value of the pressure sensor range to choose?

When selecting the range of the pressure sensor, you can follow the pressure values available in the technical documentation of the sensor. If no such data is available, the pressure can be estimated based on the generation of the Common Rail system. Approximately the first generation (around 2000) had 150MPa sensors, the second generation (2001-2007) increased the range to 180MPa, the third generation (around 2008-2014) required 200MPa sensors, and the current fourth generation is based on sensors with a range of 250MPa (given values are estimates and may vary depending on the manufacturer and system variant).

 

When testing the signal from the sensor, how can I be sure that the sensor is good?

By reading the voltage value from the sensor and converting it into pressure, we rely on its accuracy and reliability of the pressure range established. RPT-5 offers the possibility of verifying the sensor indications by comparative measurement. In this way, you can attach a second, reference sensor to the system and connect it to the RPT-5 using an optional cable. In this way, the tester will power an additional sensor and will allow for the simultaneous measurement and comparison of both sensors.

 

Can I test sensors other than pressure sensors?

The tester can be used to test other sensors with a 5V supply and voltage output. When testing other sensors, set the unit to ‘voltage’ to get the raw value from the tested sensor.
