Pressure Sensors for Diesel Engine Monitoring of Locomotive, Marine, and Back-up Generators
Proper monitoring of dynamic combustion pressure in diesel engines allows for extended maintenance intervals, improved fuel efficiency, and lower NOx emissions. Piezoelectric pressure sensors feature sensing elements with very fast response times, and are best suited for continuous monitoring or periodic walk-around cylinder balancing.
Series 105
- Small and robust enough to fit inside engine
- Ranges to 3600 psi (250 bar)
- High temperatures to +570 °F (+300 °C)
- M5 floating nut with 4.2mm front seal
Series 175

Accelerometers for Diesel Engine Monitoring
Industrial, case isolated accelerometers are ideal for use with route-based data collectors or may be used for continuous machinery monitoring of critical reciprocating equipment. They allow diesel engine bearings to be monitored for wear, overall engine knock detection and gas leakage around valves or seals.
