Bently Nevada 990 Vibration Transmitter: Reliable Machine Health Monitoring

Core Technical Specifications

• Brand & Model: This unit is the Bently Nevada 990-04-70-02-01.
• Measurement Range: The device accurately measures vibration from 0 to 4 mils (0 to 100 micrometers peak-to-peak).
• Frequency Response: It detects vibration frequencies within a broad range of 5 Hz to 6,000 Hz.
• Output & Accuracy: The transmitter provides a highly reliable 4-20 mA, two-wire output signal. It maintains an excellent accuracy of ±1.5% across its full measurement scale.
• Power Supply: The unit operates on a 12-35 VDC loop power supply, with 28 VDC recommended for installations in hazardous locations.

Environmental Durability & Compliance

• Operating Temperature: It performs consistently in extreme temperatures from -40°C to 85°C (-40°F to 185°F).
• Environmental Protection: The housing can withstand environments with up to 95% relative humidity, non-condensing.
• Hazardous Area Certification: The transmitter carries approvals for use in Class I, Zone 2/Division 2 hazardous locations.
• Electrical Protection: It includes built-in current limiting at 23 mA to protect against overload conditions.

Installation & Integration Guide

• Compatible Sensor: The transmitter works with one Bently Nevada 3300 NSv proximity probe.
• Probe Gap Setting: For optimal performance, set the probe tip to target gap between 0.5 mm and 1.75 mm (20-55 mils).
• Target Requirements: Ensure the observed target material is ferrous and has a minimum diameter of 9.5 mm (0.375 inches).
• Cable & Load: Use a maximum probe cable length of 3 meters. The total loop resistance must be less than 1000 Ohms at 35 VDC.
• Fault Indication: The output will drop below 3.6 mA within 100 microseconds to signal a system fault, resetting within 2-3 seconds.
