The 330400 and 330425 acceleration sensors are designed specifically for measuring the acceleration of critical machinery casings, especially suitable for scenarios such as gear meshing monitoring. Both comply with the American Petroleum Institute API 670 standard, with the main differences being range and sensitivity:
330400: Range of 50 g peak, sensitivity of 100 mV/g, suitable for monitoring moderate vibration intensity.
330425: Larger range (75 g peak), sensitivity of 25 mV/g, suitable for high vibration intensity scenarios.
Serial number without "G" (produced before April 2004):
When there is no installation base: 980 mm/s ²/mstrain (0.100 g/mtrain), with high strain sensitivity, it needs to be used in conjunction with a dedicated installation base.
When equipped with a mounting base: 4.9 mm/s ²/mstrain (0.0005 g/mtrain), it can effectively reduce substrate strain interference.
