BENTLY 1701/10 Vibration Monitoring Module
1. Product Description
The BENTLY 1701/10 is a cost-effective, entry-level vibration monitoring module designed for BENTLY Nevada’s machinery protection systems. It’s mainly used to collect and process basic vibration data from small to medium-sized rotating equipment (such as small motors, pumps, and light-duty compressors) in industrial settings like workshops, small factories, or auxiliary power facilities.
Working with BENTLY proximity probes, it detects abnormal vibration (e.g., from loose parts or minor bearing wear) to alert users of early equipment issues—helping avoid unexpected breakdowns. It has a simple, compact design that’s easy to install in small control cabinets, and it’s built to handle common industrial conditions (like mild vibration or temperature changes), making it a practical choice for budget-friendly or basic monitoring needs.
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 key vibration point of equipment)
- Input Signal: Accepts signals from BENTLY basic proximity probes (e.g., 3300 series entry models)
- Measurement Range: 0–127 μm peak-to-peak (covers typical vibration levels of small rotating machinery)
- Operating Temperature: 0°C to +55°C (works in standard indoor industrial environments)
- Dimensions: Compact size (approx. 110 mm × 75 mm × 35 mm) for space-saving cabinet mounting
- Protection Features: Basic short-circuit protection for input channels (prevents module damage from wiring mistakes)
- Output: 4–20 mA analog output (sends vibration data to simple controllers or HMIs for easy monitoring)
3. System Introduction
The 1701/10 is a basic component of BENTLY Nevada’s “Machinery Protection and Condition Monitoring System”—a scalable lineup that ranges from entry-level to high-end solutions. This system for basic applications includes the 1701/10 module, basic proximity sensors, a simple controller, and easy-to-use monitoring software.
In the system, the 1701/10 acts as a “basic data collector”: it takes raw vibration signals from sensors, converts them into usable data, and sends it to the controller. If vibration levels go above preset limits, the controller triggers simple alarms (like indicator lights or buzzers) to notify maintenance staff. This system is ideal for small-scale operations where complex monitoring isn’t needed, helping keep equipment running smoothly at a low cost.
