Bently Nevada 177230-02-01-CN Seismic Transmitter for Industrial Vibration Monitoring

Product Overview

The Bently Nevada 177230-02-01-CN Seismic Transmitter delivers accurate vibration measurement for industrial machinery. This device converts mechanical vibration into a standard 4-20 mA current loop signal, enabling seamless integration with PLC, DCS, and SCADA systems. Designed for harsh environments, it features a hermetically sealed 316L stainless steel housing and operates reliably in 100% non-submerged humidity conditions.

Technical Specifications

The 177230-02-01-CN offers a measurement range of 0 to 50.8 mm/s (0 to 2.0 in/s) with a frequency response of 10 Hz to 1 kHz (600 to 60 kcps) RMS. It provides a 4-20 mA output proportional to peak vibration levels, with full-scale range options including 25.4 mm/s (1.0 in/s) ±10%. The transmitter operates on 12 to 30 Vdc excitation voltage, current limited to 40 mA. Settling time is less than 15 seconds within 2% of final value. Mounted resonant frequency exceeds 12 kHz, and transverse sensitivity is less than 5% of sensitivity. The sensing element type is ceramic/shear.

Industry Applications

This seismic transmitter is ideal for monitoring rotating machinery such as pumps, fans, compressors, and turbines in industries like oil and gas, power generation, and manufacturing. Its robust design and reliable 4-20 mA output make it suitable for continuous vibration monitoring in critical equipment, helping to prevent unplanned downtime and extend asset life.

Installation & Setup Guidance

The 177230-02-01-CN mounts via a 1/4-28 UNF hole in the body, with additional mounting thread options of M6 x 1 SI and M8 x 1.25 SI. Recommended mounting torque is 4 to 7 N-m (35.4 to 62.0 in-lbf). The 3-pin MIL-C-5015 connector provides wiring for the 4-20 mA loop (Pin A positive, Pin B return) and an unbuffered dynamic acceleration signal (Pin C). Ensure proper grounding and follow manufacturer guidelines for optimal performance.

Maintenance & Reliability

The hermetically sealed sensor and 316L stainless steel construction ensure long-term reliability in demanding industrial environments. The transmitter operates from -40°C to +85°C (-40°F to +185°F) and withstands shock survivability up to 9.810 m/s² (1.000 g peak) drop test. Regular inspection of the connector and mounting integrity is recommended to maintain accurate vibration readings.

Selection Guide & Purchasing Advice

When selecting the 177230-02-01-CN, verify compatibility with your system's power supply (12-30 Vdc, current limited to 40 mA) and confirm the required measurement range and frequency response.
