BENTLY 990-10-XX-02-00, 163930-01

Description

BENTLY 990-10-XX-02-00 Vibration Transmitter with MOD:163930-01

1. Product Description

• Single-Channel Monitoring: Supports one input channel for vibration velocity or acceleration measurements using BENTLY’s 3300 NSV proximity probes.
• 4–20 mA Output: Provides a loop-powered analog signal proportional to vibration amplitude (0–10 mils peak-to-peak), compatible with PLC/DCS systems.
• Non-Interacting Zero/Span Adjustment: Front-panel potentiometers allow field calibration without affecting the output signal.
• Robust Design: Operates in temperatures from -35°C to +85°C and withstands high humidity (up to 100% condensation), making it suitable for extreme industrial environments 20.
• MOD:163930-01 Compatibility: Includes a 5-meter or 7-meter system length option for extended sensor cabling, ensuring flexibility in installation.

6. Selection Recommendations

• Equipment Type: Choose the 990-10-XX-02-00 for single-point monitoring of low to medium-speed machinery (up to 8,000 RPM). For multi-point or high-speed applications, consider dual-channel models like the 990-16-XX-02-00.
• Environmental Needs: Prioritize this model for installations with moderate vibration (≤5g) and high humidity, as its rugged design balances durability and cost.
• System Integration: Ensure your PLC/DCS accepts 4–20 mA inputs; use a protocol converter if digital communication (e.g., Modbus) is required.
• Budget Constraints: Ideal for projects requiring basic vibration monitoring without advanced analytics.

7. Precautions

• Installation:
  • Mount the module at least 10 cm away from power cables to minimize EMI; use shielded cables for sensor connections.
  • Calibrate sensors using a certified vibration shaker to establish accurate baselines.
• Configuration:
  • Set alarm thresholds according to ISO 1940 (bearing vibration standards) or equipment manufacturer guidelines.
  • Test the 4–20 mA output during commissioning to verify signal integrity.
• Maintenance:
  • Inspect LED indicators monthly; clean dust from ventilation slots in high-dust environments.
  • Replace the module every 10 years or after sustained exposure to extreme temperatures.
• Safety:
  • De-energize the system before servicing to prevent electrical shocks.
  • In hazardous environments, use explosion-proof enclosures compliant with local standards (e.g., ATEX Zone 2).
