Description

The 330400-01-CN is an industrial accelerometer designed for critical machinery casing vibration monitoring, featuring a 1/4-28 UNF integral mounting stud (Option 01) and designated with the -CN suffix for Chinese hazardous area compliance (NEPSI/CCC). This transducer delivers a sensitivity of 100 mV/g with a measurement range of 50 g peak, meeting the requirements of API Standard 670 for casing acceleration measurements such as gear mesh monitoring and overall machinery protection.

This unit provides a frequency response of 10 Hz to 15 kHz and is constructed with a 316L stainless steel housing for harsh environments. The 330400 is intended for mounting directly on bearing housings or machine casings; accurate installation is essential to ensure signal integrity and avoid false readings. The -CN suffix indicates the configuration is certified for use in China hazardous areas, adhering to local NEPSI and CCC requirements.
