177230-01-02-05 | Bently Nevada Seismic Transmitter 25.4 mm/s

Introduction to the Bently Nevada 177230-01-02-05

When machine vibration threatens uptime, the 177230-01-02-05 from Bently Nevada provides a reliable measurement solution. This seismic transmitter converts vibration velocity into a standard 4-20 mA current loop signal, enabling seamless integration with PLCs, DCS, and SCADA systems. With its rugged 316L stainless steel construction, it is built for harsh industrial environments.

Key Features & Technical Specifications

The 177230-01-02-05 is engineered for accuracy and durability. Its key specifications include:

• Measurement Range: 0 – 25.4 mm/s (0 – 1.0 in/s) peak
• Frequency Response: 3 Hz to 1 kHz (±10%)
• Output Signal: 4-20 mA current loop (proportional to peak vibration)
• Excitation Voltage: 12 to 30 Vdc (current limited to 40 mA)
• Settling Time: Less than 15 seconds within 2% of final value
• Mounted Resonant Frequency: Greater than 12 kHz
• Transverse Sensitivity: Less than 5% of sensitivity
• Operating Temperature: -40°C to +85°C
• Enclosure: 316L stainless steel, hermetically sealed

These specs translate into reliable performance that reduces unplanned downtime—a direct cost saving for any facility.

Cost-Effective Vibration Monitoring

Investing in the 177230-01-02-05 offers long-term value. By providing continuous, accurate vibration data, it helps detect bearing wear, imbalance, or misalignment early. Early detection means you can schedule maintenance during planned outages instead of reacting to catastrophic failures. This proactive approach lowers repair costs and extends machinery life.

Applications & Use Cases

This seismic transmitter is ideal for rotating equipment such as pumps, fans, compressors, and motors. It is particularly suited for remote monitoring where a 4-20 mA signal can be transmitted over long distances without signal degradation. In petrochemical plants, power generation facilities, and water treatment plants, the 177230-01-02-05 helps maintain operational efficiency.

Installation & Setup

Mounting the 177230-01-02-05 is straightforward. It features a 1/4-28 UNF mounting hole and optional M6 or M8 threads. Recommended mounting torque is 4 to 7 N-m (35.4 to 62.0 in-lbf). The 3-pin MIL-C-5015 connector simplifies wiring: Pin A is the 4-20 mA positive loop, Pin B is the loop return, and Pin C provides a dynamic acceleration signal. Ensure the excitation voltage is within 12-30 Vdc and the loop current is limited to 40 mA.

Maintenance & Reliability

With a hermetically sealed sensor and 316L stainless steel case, the 177230-01-02-05 withstands harsh conditions, including 100% relative humidity (non-submerged). It is designed for minimal maintenance—just periodic verification of output signal and physical inspection. This reliability reduces maintenance labor and replacement costs over the product's life.

Compatibility & Integration

The 4-20 mA output makes the 177230-01-02-05 compatible with virtually any PLC, DCS, or SCADA system that accepts analog inputs. It is designed for systems with internal power supplies typically current-limited to 30-35 mA. This universal compatibility simplifies integration into existing control architectures.
