1. Product Description
The BENTLY 990-10-XX-02-00 serves as a critical interface between vibration sensors and control systems, converting raw mechanical vibrations into standardized electrical signals for real-time monitoring. Key features include:
- 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.
The 990-10-XX-02-00 is ideal for OEMs and end-users seeking a simplified vibration monitoring solution without the complexity of high-end systems.

4. Application Areas and Case Study
Application Areas:
- Manufacturing: Monitoring conveyor motors, mixers, and packaging machinery.
- Energy: Tracking vibrations in auxiliary pumps and fans in power plants.
- Water/Wastewater: Ensuring reliability of blowers and pumps in treatment facilities.
Case Study:
A chemical plant in Germany deployed the 990-10-XX-02-00 with MOD:163930-01 to monitor vibrations in six process pumps. The module’s 4–20 mA outputs integrated with the plant’s PLC, enabling early detection of a failing bearing in a critical pump. By replacing the bearing during a scheduled maintenance window, the plant avoided a potential 12-hour production halt, saving over €45,000 in lost output and repair costs.
5. Competitive Comparison
Compared to similar compact vibration transmitters, the 990-10-XX-02-00 offers:
- Dual Sensor Compatibility: Supports both velocity and acceleration measurements without additional signal conditioners.
- Superior Temperature Range: Operates 15°C colder and 10°C hotter than most budget alternatives.
- Integrated Alarm Functionality: Built-in non-OK/signal defeat circuit prevents false alarms due to sensor faults.

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).
