Technical Data of the Knocking Sensors

 

Use MOTORTECH knocking sensors

DetCon detonation control systems are parameterized for operation with MOTORTECH knocking sensors (piezoelectric acceleration transducers). The use of other sensors entails a new calibration of the engine.

 

The MOTORTECH knocking sensors have the following technical data:

> 20 kHz

Temperature range

-40 to +130 °C (-40 to +266 °F)

Dimensions, Sensor

45 x 20 x 21 mm (1,77 x 0,79 x 0,83'')
(see Mounting the Knocking Sensors)

Sensor mount

Cast iron: M8 x 25 mm (0.98")
Aluminum: M8 x 30 mm (1.18")
