P3 Top Class Pressure Transducer: Precise Pressure Measurement

The P3 Top Class pressure transducer facilitates extremely precise pressure measurement and, owing to its excellent accuracy class of 0.1, is ideal for the measurement of not only static pressure but also dynamic pressure variations, pressure peaks, and pressure fluctuations.

The P3 Top Class is suitable for pressure measurement in industrial applications such as those incorporating diesel and hydraulic technologies. Its monolithic measuring body has no weld seams and is tremendously stable and robust. Each pressure transducer is individually tested, and for each, an individual, extensive test record is available, which specifies values such as linearity and individual temperature dependence, in addition to the sensitivity and characteristic curve deviation. Additionally, the pressure transducer has a PT100 temperature sensor in order to ensure comprehensive and accurate measurement results. This facilitates the correct measurement of temperature variations and significantly reduces the measurement uncertainty due to reduced temperature effects.

  • Accuracy class: up to 0.1
  • Nominal (rated) pressure: 10 bar to 3,000 bar
  • Degree of protection: IP67


  • Each transducer is individually tested, and an extensive test record is available
  • Excellent repeatability and reproducibility of the exact measurement results
  • High-grade strain gauge technology from HBM
  • Temperature influence on the zero signal of only 0.05% / 10K
  • Tight sensitivity tolerance for the parallel connection of multiple transducers

High-quality results due to high measurement accuracy and temperature measurement


  • High stability owing to the robust, monolithic steel measuring body without weld seams
  • Protection against pressure peaks due to high overload range with up to 2.5–fold nominal (rated) pressure
  • Resistant to humidity and dirt owing to IP67 degree of protection

Robust due to the stable measuring body and high overload range


  • Eleven nominal (rated) pressure ranges are available (10; 20; 50; 100; 200; 500; 750; 1,000; 2,000; 2,500; 3,000 bar)
  • Temperature compensation due to integrated Pt100 temperature sensor
  • Broad operating temperature range from –40 °C to +100 °C
  • Many cable lengths and connectors are available alongside an optional Plug-and-Play connector

Wide range of applications due to different nominal (rated) pressure values
