Piezo sensor KS：

The vibration sensors of the KS series are used to detect absolute vibrations on machines and system components in the frequency range of approx. 0.5Hz to 10kHz and temperature range of -20 to 120°C. The PIEZO sensors work according to the shear principle with IEPE supply.

The shear principle PIEZO sensors with IEPE supply provide a voltage signal proportional to the acceleration, which is modulated onto the phantom supply.

The robust, double-shielded stainless steel housing ensures good signal quality even in rugged industrial applications with EMC exposure.

Insulated housing to avoid ground loops

Double shielding for improved EMC protection

M12 connector for easy mounting

Measurement in all directions

Temperature range from -20 ... 120°C
