Basic Parameters
Dimensions:127mm×127mm×76.2mm(5 inches×5 inches×3 inches).
Weight:Approximately 1.03kg(2.26 pounds).
Power Input:DC input 18-36VDC,maximum 7.5W.
Operating Temperature Range:-30°C to+65°C(-22°F to+149°F).
Storage Temperature Range:-40°C to+85°C(-40°F to+185°F).
Input/Output
Vibration Input:Supports two seismic vibration channels,compatible with ICP accelerometers or custom accelerometers(2-wire or 3-wire).Each channel performs independent 24-bit A/D conversion.Speed/Key Phase Input:Supports key phase sensors such as eddy current probes,proximity switches,and reluctance transmitters.Speedinputs are up to 20kHz and cover a speed range of 1 to 120,000 RPM.
Outputs:Includes two programmable relay outputs,configurable to be normally energized or normally de-energized;two 4-20mA outputs;and three buffered sensor outputs(including a speed signal)accessible via BNC connectors with short-circuit and EMI protection.
Features
Continuous Monitoring and Protection:Provides real-time monitoring of key measurements such as vibration amplitude,setpoint,and speed,including peak,peak-to-peak,and RMS values,and allows for real-time alarm configuration.
Synchronous Sampling:Synchronous sampling of the two acceleration and vibration inputs facilitates advanced diagnostic analysis.
Display and Indication:Equipped with an LCD display,vibration amplitude,setpoint,and speed information is displayed,while LED indicators indicate monitor status.Communication:The monitor can be configured via the Bently Nevada Monitor Configuration Software via an Ethernet 10/100Base-T communication interface.Modbus Ethernet communication is also optional.
Contact Inputs:Contact inputs are provided for channel bypass,configuration lockout,and reset.
Applications:Suitable for vibration monitoring and protection of equipment such as pumps,compressors,fans,and motors in industries such as oil and gas,power generation,water treatment,pulp and paper,and manufacturing.
