The new HiPreMa 4X line of instruments.

26/01/2022Related article product, Techs

We have updated the entire HiPreMa 4 product line. HiPreMa 4X is born!!!

What is more accurate than HPM 4?
It’s HPM 4X!

The new technical features of the HiPreMa 4 X line.

The mechanical part remained the same, we redesigned the entire electronic part of our instruments from an 8-bit micro controller to a 32-bit micro controller.

Due to this change in technology, the instrument’s computing speed is four times faster than the old microcontroller.

This has thus enabled us to further improve accuracy in tire pressure and temperature measurements and implement new functions across the entire instrument line.

Updates in Pressure measurement functionality

Tire pressure and temperature in motorsports are key parameters in achieving the best possible performance on the track.

It was not enough to be more accurate to the hundredth of a bar (0.01 BAR): now our reference is the microbar, 4 decimal places after the decimal point.

Even more extreme precision made possible by the computational capacity of the new electronics.

Prisma Electronics is a technical partner of the Aprilia Racing Team in the Moto Gp World Championship.
Instrument calibration is performed with a sample reference of 0.0001 Bar pressure.

One very useful function that has been introduced is the ability to store the Vehicle Number for each session.

For each session saved in the memory of the instrument, in addition to Date and Time of the session, Atmospheric Air Temperature, Cold and Hot Pressures and their variation, it is possible to activate storage of the vehicle number.

This is a very useful function for tire technicians on Teams, for technicians from the various tire manufacturers who have to manage data from different cars.

The memory of the new instrument can save up to 50 full sessions-a full weekend of competition stored on your instrument.

The PRESSURE SHOT function has been optimized to automatically store hot pressures without having to press any buttons.

The main features of the HiPreMa 4X line for digital tire pressure gauge functionality are(Upgraded functionality on all instruments with pressure measurement functionality):

  • Accuracy of measurement : +/- 0.0005 Bar
  • Storage of 50 full sessions
  • Function for storing the vehicle number for each session
  • 32-bit technology with 4 times faster computing speed
Visualization of the difference between the cold and hot pressures you have at the end of a session on the track. Important value to understand the dynamic balance of the vehicle and the load on each tire.
Displays the difference between Cold and Hot Pressures at the end of a track session, which is important for understanding the dynamic balance of the vehicle and the load on each tire.


Updates in temperature measurement capabilities

In addition to pressure, the key parameter for understanding and optimizing the performance of tires is their Usage Temperature.

It is critical to stay within the correct tread temperature usage window to optimize mechanical grip and keep tire decay under control.

It is important to measure the temperature of the compound with speed.

For this reason we halved the thermocouple reading time, now in less than 100 milliseconds the instrument reads the temperature of the thermocouple or infrared sensor.

Now our Pyrometers, with both needle probe and infrared sensor, thus have a temperature measurement resolution of 0.1°C and a measurement error of 0.25°C.

So here, to summarize, what changes in HPM4 X when we measure temperatures?

  • Measurement resolution 0.1 °C
  • Accuracy of measurement : +/- 0.25 °C
  • Reading time – Thermocouple – Infrared : 0.1 sec.
  • Storage of 50 full sessions
  • Function for storing the vehicle number for each session
  • 32-bit technology with 4 times faster computing speed

New functions in Digital Chronometer Mode 4 Pilots

The only digital stopwatch on the market that allows 7 full sessions to be stored in the instrument’s memory.

The 4 Rider Digital Chronometer part has new firmware that allows for new functions implemented.

In fact, up to 7 full sessions can now be stored in the instrument, and for each session, up to 30 laps per rider and nine split times per lap. As well as, of course, the date and time of the session and air temperature.

In addition, for each session from the menu, you can recall the three best laps for each driver (in the first screen), and then you can review all the laps of the session and related split times.

Thanks to this new feature, we have in the memory of the instrument a complete day of testing.

The instrument is capable of storing 840 laps in total.

The new features in the stopwatch function (found in all instruments that have the Stopwatch mode):

  • 7 Sessions storable in the instrument including Date – Time – Air Temperature for each session
  • 1 Screen that quickly summarizes the 3 best laps of the session for each driver and their split times
  • Recall of all laps of the session and their split times (Max. 30 laps per session)
  • Capacity to store 840 Turns + 7560 Intertemps
Multi pilot stopwatch
Display of current session in Chronometer mode – 7 Sessions can be stored in the instrument.
