CYLINDER HEAD PRESSURE TRANSDUCER

A cylinder head pressure transducer measures the rapid, dynamic pressure changes inside an engine cylinder through an access port in the cylinder head. It converts the pressure into an electrical signal for monitoring, testing, and analysing engine performance.

The features include: 

• Ground-isolated
• Additional cooling not required
• Low thermal shock error, very low load-change drift
• High sensitivity using a piezo-star crystal

The sensing element used is a quartz crystal that generates an electrical charge proportional to changing pressure. The sensor is characterised by minimal thermal shock and outstanding linearity. They capture high frequency pressure spikes during the engine cycle. Its ground-isolated design makes it ideal for test stands with ground loop problems. The shoulder sealing of the sensor allows it to be mounted with its front flush with the cylinder head.

The high-temperature sensor is supplied with a shielded cable to withstand peak combustion temperatures and to eliminate false pressure changes. The precision charge
amplifier has a digital thumb wheel for calibration purposes.

The sensor assembly can be easily fitted to a plug, which can then be fitted onto the cylinder head. 

Pressure Range: 0-300 bar

Sensitivity: approximately 37 p.C/bar

Key features:

• Significantly enhances practical investigations, demonstrations and studies of internal combustion engines.
• For use with TecQuipment’s Engine Cycle Analyser (ECA100).
• Designed to measure in-cylinder pressure during compression, combustion and expansion strokes.
• Captures rapid pressure changes during engine operation, making it suitable for combustion analysis and pressure v/s Crank-angle measurements.
• Suitable for the thermal conditions associated with engine combustion, with temperature limits specified for the sensing element, mounting interface, and electrical connector.
• Provides consistent pressure readings over repeated engine cycles, supporting the evaluation of peak cylinder pressure, compression pressure and combustion behaviour.

Essential Ancillaries:

• Engine Cycle Analyser (ECA100)
• Crank Angle Shaft Encoder (ECA102)
• Suitable Computer – see specifications 

TecQuipment also offers a complete package (the ECA100S). This includes the ECA100, one ECA101 and one ECA102.
