Product Introduction: 3300/40-03-01-01-00-00
The 3300/40-03-01-01-00-00 is a Seismic Transmitter from the Bently Nevada 3300 monitoring series. This device is a rugged, 4-20 mA two-wire loop-powered transmitter designed to continuously monitor the overall vibration velocity of machine structures like bearing housings, casings, or bases. It integrates a velocity sensor with sophisticated signal conditioning electronics to provide a standard analog output that is directly proportional to the vibration level. This allows for easy integration into PLCs, DCS, or other control systems for machinery protection and predictive maintenance.

Application Scenarios
This transmitter is widely used for general-purpose machinery protection where a simple, robust 4-20 mA vibration signal is required.
Pump Monitoring:
Monitors overall vibration on centrifugal and positive displacement pumps in water treatment, chemical processing, and HVAC systems to detect imbalance, bearing wear, and cavitation.
Fan and Blower Protection:
Used on induced draft (ID) and forced draft (FD) fans, cooling tower fans, and industrial blowers to provide early warning of mechanical failure.
Motor Bearings:
Installed on the bearing housings of large electric motors (e.g., in compressors, conveyors) to monitor health and schedule maintenance based on actual condition.
General Industrial Machinery:
Provides cost-effective vibration monitoring for mixers, gearboxes, and compressors that are not critical enough to require a full proximity probe system but still benefit from continuous protection.
Integration into Control Systems:
Its standard 4-20 mA output allows for easy connection to existing plant Distributed Control Systems (DCS) or Programmable Logic Controllers (PLC) for alarm and shutdown functions.
