Pressure Transducers Help Provide Automotive R&D

Sales contact



If you think that pressure transducers could not possibly help keep the price of gas and other fossil fuels in check, think again. When prices rise, it becomes more important to increase automotive efficiency and study alternative fuels, fuel additives, and emissions. Hydraulically operated automotive test stands provide a platform for this research and development (R&D). Pressure transducers play a big role in automotive test stands.

How automotive test stands are used

Automotive test stands commonly perform R&D in the following fields:

  • Fuel additives, fuel composition, and fuel pressure analysis
  • Diesel and spark ignition technology
  • Powertrain and drivetrain control
  • Transmission fluid pressure
  • Emissions science
  • Engine design

The types of automotive test stands that most often use pressure transducers include hydraulically operated engine and chassis dynamometers. Dynamometers are used to test torque, RPM, and power relationships in diesel and gasoline engines. While engine dynamometers are typically mounted to the engine flywheel housing, chassis versions measure torque output at the drive wheels.　

How pressure transducers help

Hydraulic dynamometers use pressure transducers to measure and control:

  • Hydraulic fluid pressure
  • Pump pressure
  • Lubricant pressure

Production automotive test stands in test and measurement applications require pressure transducers to be compatible with common hydraulic fluids including water and lubricating oils. The

WIKA S-10, S-11, and the P-30 electronic pressure transducers provide accuracy, precision, and temperature stability in automotive test stands. These pressure transducers can also withstand environmental conditions, provide a stable signal, and deliver repeat performances.
