Сonverter DN-3 (DN 3, DN3)

It is intended to convert mechanical vibrations into electrical signals proportional to the acceleration of the oscillating object.
Operating frequency range from * (defined input parameters, vibration measuring devices) to 4000 Hz.
Insulation resistance: under normal circumstances at least 1 G W, in conditions of high humidity of at least 0.1 G W.

Сonverter DN-3 piezoelectric vibration measurement (hereinafter vibrator) is designed to convert mechanical vibrations into electrical signals proportional to the acceleration of the vibrating object.
Vibrator DN-3 is used in conjunction with vibration measuring devices to measure vibrations in the plant or in the laboratory. Vibrator is a nd a beautiful complex.
Operating conditions vibrator DN-3: temperature from 243K to 343K (from -30 ° C to 70 ° C), (when fixing the wax to a temperature of 313 K (40 ° C), relative humidity of 90% at an ambient temperature of 300 K (plus 27 ° C), acoustic noise up to 140 dB, and the value of the inverter output voltage in the frequency range of 200-4000 Hz, less than 2.5 mV external magnetic field strength of 400 A / m, the output voltage of the inverter is not more 50 mV, the acceleration shock of 5000 m / s, the pulse duration within 0,015-12,5 ms.
