177230-02-02-05 | Bently Nevada Seismic Transmitter 0-50.8 mm/s

Why Accurate Vibration Monitoring Matters

When rotating machinery operates outside safe vibration limits, the consequences can be costly. Unplanned downtime, equipment damage, and safety risks are just a few of the challenges. The 177230-02-02-05 from Bently Nevada provides a reliable solution. It converts vibration into a standard 4-20 mA signal, enabling continuous monitoring with your existing PLC, DCS, or SCADA system.

Key Features of the 177230-02-02-05

• Measurement range: 0 to 50.8 mm/s (0 to 2.0 in/s) peak, covering typical industrial vibration levels.
• Frequency response: 3 Hz to 1 kHz (180 to 60 kcpm) ±10%, capturing relevant machine dynamics.
• Output: 4-20 mA current loop, proportional to peak vibration, simplifying integration.
• Excitation voltage: 12 to 30 Vdc, current limited to 40 mA, compatible with most systems.
• Multiple approvals: CSA/NRTL/C, ATEX/IECEx, ensuring suitability for hazardous areas.
• Rugged construction: 316L stainless steel case and connector, rated for 100% non-submerged humidity.
• Compact size: 25.4 mm diameter, 66.0 mm height, and 0.131 kg weight, easy to mount.

Reliability and Long-Term Value

Investing in the 177230-02-02-05 reduces maintenance costs and extends equipment life. Its hermetically sealed sensor and ceramic/shear sensing element provide stable performance. With a settling time of less than 15 seconds and a mounted resonant frequency above 12 kHz, it responds quickly and accurately. This reliability translates into fewer false alarms and better decision-making.

Installation and Setup

Mounting is straightforward with a 1/4-28 UNF hole or M6/M8 threads. Apply a mounting torque of 4 to 7 N-m (35.4 to 62.0 in-lbf) to ensure proper coupling. The 3-pin MIL-C-5015 connector simplifies wiring: Pin A for 4-20 mA positive loop, Pin B for loop return, and Pin C for dynamic acceleration signal. Always follow the manufacturer's manual for safe installation.

Applications Across Industries

This transmitter is ideal for fans, pumps, motors, and other rotating equipment in industries such as oil and gas, power generation, and manufacturing. Its ATEX/IECEx approvals allow use in explosive atmospheres, while the 100% humidity rating suits washdown environments. Whether monitoring a critical compressor or a ventilation fan, the 177230-02-02-05 delivers dependable data.

Maintenance and Troubleshooting

Regular inspection per the manufacturer's manual ensures long-term accuracy. Check the mounting integrity and connector condition periodically. If readings drift, verify the excitation voltage and loop wiring. The transverse sensitivity is less than 5%, minimizing cross-axis errors. For persistent issues, consult the official Bently Nevada documentation or contact Petro Auto Tech.

Compatibility and Integration

The 4-20 mA output is universally accepted by PLCs, DCS, and SCADA systems. It operates with internal power supplies that are current limited between 30 mA and 35 mA, making it easy to retrofit into existing loops. No special software is required—just configure your input channel for 4-20 mA and scale accordingly.
