Product Introduction: 3300/46-08-03-01-00
The 3300/46-08-03-01-00 is a 4-20 mA Dual-Channel Accelerometer System from the Bently Nevada 3300 series. This system is designed for monitoring high-frequency vibration (in units of acceleration) of machine structures, such as bearings and casings, using two independent piezoelectric accelerometers. Each channel includes a signal conditioner that converts the accelerometer's raw signal into a standardized, loop-powered 4-20 mA output, which is proportional to the vibration acceleration level. This dual-channel configuration is ideal for monitoring vibration in two planes or for redundant monitoring on a single critical point, providing robust machinery protection with easy integration into control systems.

Application Scenarios
This dual-channel accelerometer system is a versatile solution for monitoring high-frequency vibration and shock in various industrial applications.
High-Frequency Vibration Monitoring:
Used to detect rolling element bearing defects, gear mesh issues, and blade-pass frequencies in fans, pumps, gearboxes, and compressors, where high-frequency vibration components are key indicators of failure.
Reciprocating Machinery:
Ideal for monitoring the structure of reciprocating compressors and engines to detect impacts, valve failures, and other high-frequency events.
Critical Machine Protection:
Provides redundant monitoring on a single critical point or monitors vibration in two orthogonal directions on a bearing housing for a more complete picture of machine health.
Integration into Control Systems:
The independent 4-20 mA outputs for each channel allow for straightforward connection to PLCs, DCS, or SCADA systems for plant-wide monitoring, alarm, and shutdown functions.
General Purpose Vibration Monitoring:
A robust solution for a wide range of industrial assets where casing-mounted vibration measurement in acceleration units is required for predictive maintenance.
