BENTLY 1701/15 Vibration Monitoring Module
1. Product Description
The BENTLY 1701/15 is a dedicated vibration monitoring module designed for BENTLY Nevada’s machinery protection systems. Its main role is to collect and process vibration data from rotating equipment (such as turbines, compressors, and motors) in industrial settings—like power plants, oil refineries, and manufacturing facilities.
It works with vibration sensors to detect abnormal shaking or movement of equipment, which helps spot early signs of faults (e.g., bearing wear or imbalance) before they cause serious damage. With a compact design, it’s easy to integrate into existing control cabinets and built to handle tough industrial conditions (like high temperature or vibration), ensuring reliable long-term operation.
2. Technical Specifications
- Power Supply: 24 V DC (18–32 V DC, wide input for industrial stability)
- Monitoring Function: Single-channel vibration measurement (focuses on one vibration point of equipment)
- Input Signal: Accepts signals from BENTLY proximity probes (e.g., 3300 series) for accurate vibration detection
- Measurement Range: 0–254 μm peak-to-peak (covers typical vibration levels of industrial rotating machinery)
- Operating Temperature: 0°C to +60°C (works in standard factory or plant environments)
- Dimensions: Compact size (approx. 120 mm × 80 mm × 40 mm) for space-saving cabinet mounting
- Protection Features: Short-circuit protection for input channels (prevents module damage from wiring errors)
- Output: 4–20 mA analog output (sends vibration data to controllers or HMIs for monitoring)
3. System Introduction
The 1701/15 is a key part of BENTLY Nevada’s “Machinery Protection and Condition Monitoring System”—a lineup used to keep rotating equipment safe and efficient. This system typically includes vibration modules (like the 1701/15), proximity sensors, controllers, and monitoring software.
In the system, the 1701/15 acts as a “data collector”: it takes raw vibration signals from sensors, processes them into usable data, and sends it to the main controller. The controller then analyzes the data—if vibration levels exceed set limits, it triggers alarms or shuts down equipment to prevent breakdowns. This system is widely trusted in industries where unplanned equipment downtime is costly, helping extend machinery life and reduce maintenance costs.
