📊 Bently Nevada 1900/27-03 Single-Channel Vibration Monitor
The Bently Nevada 1900/27-03 is a stand-alone, locally mounted vibration monitor engineered for machinery protection and condition monitoring in general-purpose and essential rotating equipment. This single-channel monitor accepts inputs from Trendmaster® 2000 accelerometers (100 mV/g sensitivity), processes signals into peak velocity units, and provides local LCD display, alarm relay outputs, and 4-20mA analog output for integration with DCS/SCADA systems in pumps, motors, fans, and compressors.

🏭 Machinery Protection Applications
Pump & Motor Monitoring: Protects centrifugal pumps, cooling water pumps, and electric motors (10-500 HP) in water treatment, HVAC, and industrial processes where bearing failures, misalignment, and imbalance cause 70% of unplanned downtime—providing early warning 30-90 days before catastrophic failure through continuous vibration trending.
Fan & Blower Surveillance: Monitors induced draft fans, forced draft fans, and process blowers in power plants, cement kilns, and ventilation systems where blade imbalance, bearing wear, and belt misalignment generate excessive vibration, enabling predictive maintenance that reduces emergency repairs by 60%.
Compressor Condition Monitoring: Tracks vibration in air compressors, refrigeration compressors, and small gas compressors (under 500 HP) where local mounting near equipment provides immediate visual indication and alarm relay outputs to plant annunciator systems, preventing compressor failures costing $20K-100K in repairs.
General-Purpose Machinery: Provides cost-effective protection for conveyors, gearboxes, mixers, and agitators in manufacturing, food processing, and chemical plants where budget constraints prevent deployment of multi-channel monitoring systems, offering essential vibration protection at 1/3 the cost of rack-based solutions.
⚙️ System Integration Features
4-20mA Trending Output: Proportional analog signal enables integration with DCS, PLC, and SCADA systems for continuous vibration trending and historical data logging, supporting predictive maintenance programs that extend equipment life by 40% through early detection of degradation patterns.
Alarm Relay Contacts: Dry contact outputs connect to plant annunciator panels, emergency shutdown systems, and remote alarm systems, providing fail-safe notification when vibration exceeds setpoints—critical for unmanned facilities and after-hours operation where immediate response prevents equipment damage.
Local LCD Display: Real-time vibration readings in peak velocity units (in/sec or mm/sec) enable field technicians to verify equipment condition during rounds, troubleshoot abnormal vibration, and confirm alarm conditions without external instrumentation, reducing diagnostic time from hours to minutes.
Trendmaster® 2000 Compatibility: Pre-configured for Bently Nevada 200150 and 190520 accelerometers eliminates calibration and setup complexity, enabling plug-and-play installation in 30 minutes versus 2-4 hours for generic monitors requiring sensor characterization and signal conditioning adjustments.
