Engine sensor – precise data for monitoring and control

Engine sensors are essential components for real-time monitoring, regulation and diagnostics in combustion engines. Whether used for temperature, pressure, vibration or knock detection – a reliable engine sensor ensures that vital operating data is continuously available. In combination with engine gauges and control systems, sensors help optimize performance, reduce wear and prevent failures.

Function and benefits

Engine sensors collect and transmit data from various engine parameters to onboard displays or control units. These include:

  • Coolant and oil temperature
  • Oil pressure and fuel level
  • Vibration, RPM and knock detection

Connected to motor gauges and engine management systems, sensors enable accurate diagnostics and early warning functions. This is particularly important in marine engines, where downtime can lead to high costs or safety risks. A matching boat gauge set ensures all sensor values are visible at a glance.

Sensor types and marine applications

From simple analog senders to complex digital transducers, motor sensors cover all critical functions in engine monitoring. In marine environments, robust marine gauges and sensors are designed to resist vibration, saltwater and temperature fluctuation.

Whether for main propulsion, auxiliary power units or generator systems – each engine sensor must be accurately calibrated, waterproof, and resistant to corrosion. All sensor types are available for MTU, MAN, Volvo Penta, Deutz, and MWM engines.

Integration and availability

Engine sensors are typically installed directly into the engine block, oil circuit, coolant system or intake path. Paired with the right engine gauges or boat gauge set, they deliver immediate feedback to the operator or the electronic control unit. We supply OEM-sensors for all common marine and industrial engines – from coolant temperature to knock detection and pressure monitoring.

FAQ

Where is the engine coolant temperature sensor?
The engine coolant temperature sensor is usually located near the thermostat housing or directly in the engine block where coolant flows. It monitors coolant temperature and sends data to the ECU or the engine gauge cluster.

What is an engine knock sensor?
An engine knock sensor detects abnormal combustion – known as “knocking” or “pinging” – caused by pre-ignition. It sends signals to the ECU, which adjusts ignition timing to protect the engine from damage and improve efficiency.
