TheBently Nevada 1720045is a versatile and compact1900/65A General Purpose Equipment Monitordesigned for the continuous protection and supervision of smaller, less critical industrial machinery. It bridges the gap between basic transmitters and high-end rack-based systems by providing eight channels of dedicated monitoring: four for vibration and four for temperature.
Model:1720045 (1900/65A Series)
Vibration Inputs:4 Channels (Configurable for Acceleration, Velocity, or Displacement)
Temperature Inputs:4 Channels (Supports RTD or Thermocouple)
Frequency Response:5 Hz to 10 kHz
Power Input:18 V DC to 36 V DC (7.2 W typical consumption)
Signal Outputs:4-20 mA analog output per channel
Relay Logic:4 SPDT relays (Rated 5 A at 250 V AC) for Alert/Danger triggering
Update Rate:High-speed 100 ms per channel
Accuracy:±1% of full scale
Form Factor:Compact DIN rail or panel mount (133 x 133 x 178 mm)
Environmental:-20°C to +70°C operating range; IP20 protection rating
Key Features & Engineering Advantages
Combined Diagnostics:By integrating both vibration and temperature monitoring into a single unit, the 1720045 provides a more complete picture of asset health than single-variable monitors.
Flexible Signal Conditioning:The vibration channels are highly configurable, allowing the same device to monitor a high-speed motor (acceleration) or a slow-moving pump (displacement) simply through software settings.
Rapid Fault Detection:With a 100 ms update rate, the monitor can trigger safety relays almost instantaneously, preventing damage during sudden mechanical events.
Seamless Integration:The standard 4-20 mA outputs and relay contacts allow for easy connection to existing PLC, DCS, or SCADA systems without requiring complex digital protocols.
Space-Efficient Design:Its small footprint is specifically engineered for easy integration into existing control panels where space is at a premium, making it ideal for skid-mounted equipment.
