BENTLY 1701/15

Product introduction

The BENTLY NEVADA 1701/15 is a rugged vibration transmitter designed for continuous monitoring of rotating machinery in industrial environments. As part of BENTLY NEVADA’s extensive portfolio of machinery protection solutions, this device converts mechanical vibration into a standardized 4-20 mA signal, making it compatible with most industrial control systems, DCS, and PLCs.

In industrial settings, early detection of abnormal vibration in equipment such as pumps, motors, and fans is crucial to prevent unplanned downtime. The 1701/15 serves as a frontline monitoring tool, capturing vibration data in the 10 to 1000 Hz range and converting it into a proportional 4-20 mA output. This allows operators to easily integrate vibration monitoring into existing control networks, enabling real-time assessment of machinery health. Unlike complex proximity systems, the 1701/15 offers a cost-effective, standalone solution for general vibration monitoring, complementing more advanced systems like those using the 79492-01 extension cable and 330180-91-05 proximitor in critical applications.

Core advantages and technical highlights

Industrial-grade durability: The 1701/15 features a 316L stainless steel housing with an IP67 protection rating, making it resistant to water, dust, and corrosive substances. This ensures reliable operation in harsh environments such as chemical plants, offshore platforms, and steel mills, where exposure to moisture and contaminants is common.

Simplified integration: With a 4-20 mA output signal, the 1701/15 seamlessly connects to standard industrial control systems without the need for specialized interfaces. This simplifies installation in existing setups, allowing for quick integration into monitoring networks alongside other sensors and transmitters.

Broad application range: Covering a vibration range of 0 to 50 mm/s and a frequency response of 10 to 1000 Hz, the 1701/15 is suitable for monitoring various rotating equipment, from small motors to large industrial fans. Its accuracy of ±2% ensures that even subtle vibration changes are detected, providing early warnings of potential issues.

Typical application scenarios

In manufacturing facilities, the BENTLY NEVADA 1701/15 is widely used to monitor electric motors driving conveyor systems. Motors are critical to production lines, and excessive vibration can indicate bearing wear or misalignment. The transmitter continuously sends 4-20 mA signals to the plant’s SCADA system, where operators can track vibration levels. When vibration exceeds predefined thresholds, alerts are triggered, allowing maintenance teams to address issues before motor failure causes unplanned downtime.

In water and wastewater treatment plants, the 1701/15 is installed on centrifugal pumps. These pumps operate in wet, corrosive environments, and vibration monitoring is essential to prevent leaks and equipment damage. The transmitter’s IP67 rating and stainless steel housing withstand these conditions, providing accurate vibration data that helps optimize pump performance and extend service life. By integrating with the plant’s control system, it enables predictive maintenance, reducing repair costs and improving operational efficiency.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the BENTLY NEVADA 1701/15, ensure the mounting surface is clean, flat, and free from paint or debris. Use a torque wrench to secure the transmitter to the M10 x 1.5 threaded stud, applying 20 Nm of torque to ensure a stable connection. Verify that the power supply is within the 18-30 V DC range and that the signal cable (22 AWG shielded twisted-pair) is properly routed away from high-voltage lines to avoid interference. Power off the system during wiring to prevent damage to the transmitter or connected equipment.

Maintenance suggestions: Inspect the 1701/15 quarterly for signs of physical damage, corrosion, or loose connections. Clean the housing with a soft cloth and mild detergent to remove dirt and contaminants. Calibrate the transmitter annually using a vibration calibrator to ensure accuracy—follow the manufacturer’s guidelines for calibration procedures. If the output signal is unstable or inaccurate, check the power supply voltage and cable connections first. Replace the transmitter if internal components fail, using only genuine BENTLY NEVADA parts to maintain performance and certification compliance.
