These sensors, non-resonant, have wide operation range between 5-15kHz. They can be applied in several types of engines and their knock frequency is determined during the calibration of the engine.

Flat output over the knock frequency band of 5-15kHz allows flexibility for use on a variety of engines (four-wheel, two-wheel, construction machinery, stationary gas engines, outboard motors, snowmobiles) Lead-free piezoelectric element (piezoelectric ceramic) – high output and low temperature dependence
