Kistler supplies a complete range revolving around engine measurement and development needs – from sensors to evaluation and indication. This includes service and calibration.

The wide range of Kistler sensors reflects the multifaceted nature of engine development. From the miniature pressure sensor through to the water-cooled type for high-precision thermodynamic analyses. Equally unique are piezoresistive sensors for precise measurement of intake and exhaust manifold pressures.

For each application Kistler supplies a wealth of function-specific amplifiers covering all of the measurement requirements for combustion analysis.

Amplifier for piezoelectric sensors
These amplifiers convert the charge output of a piezoelectric sensor into a proportional voltage.

The charge output is used as an input variable for analysis systems, and can be digitized in an analog-to-digital (A/D) converter if necessary.

Amplifier for piezoresistive sensors
Connection of piezoresistive sensors requires a piezoresistive amplifier, which serves several functions:

• Supplies measuring bridge with constant current
• Amplifies bridge voltage
• Voltage or current output selectable

The amplifier output signals can be digitized in an analog-to-digital converter (ADC) if necessary.

Depending on the application and complexity, Kistler supplies:
• Single-channel amplifier systems for measuring mechanical
  measurands (pressure, force or acceleration)
• Multichannel amplifier systems for high-bandwidth signal conditioning.
  The perfect signal conditioning system for combustion analysis in internal
  combustion engines.
• pMax module for continuous monitoring and measurement of
  peak cylinder pressure pmax in Diesel and gas engines.

TDC sensor

The TDC system is used for dynamic determination of top dead center on piston engines. The TDC sensor Type 2629B... is used for dynamic determination of TDC with the engine cranked in unfired mode. It is mounted in the nozzle holder or spark plug bore of the engine. Accurate determination of TDC is an important basis for accurate engine combustion analysis.

Extremely robust precision crank angle encoder

The crank angle encoder set Type 2614A... serves as the basis of all measurements related to crank angle.

It consists of an angle encoder and matching electronics.

• Speed range 0 ... 20 000 rpm
• Suitable for cold start measurements
• Supplies LVDS signals with a resolution of 0,5 °/1°
• Durable, withstands high mechanical loading

The optional pulse multiplier Type 2614A4 can be used if TTL signals and additional resolutions are required. It provides resolutions down to 0,1° of CA and a second angle marks signal with a resolution of 1°.

KiBox^® To Go

Combustion analysis with the new KiBox To Go
Developers need to respond rapidly and flexibly during engine tuning or troubleshooting so as to be able to validate test bench results easily during over-the-road testing. The application engineer demands a supporting tool with a high level of functionality and processing power for use in the vehicle during and after the measuring run.

Indicating power to go!
The KiBox supplements Kistler's product range with a combustion analysis system specially designed for mobile use. Its transparent interfaces integrate all of the data acquisition hardware and software into a single unit. The software for data organization, analysis and visualization is linked to the usual application environment (e.g. INCA).
