Product Overview
When machinery vibration threatens uptime, the Bently Nevada 177230-00-01-05 Seismic Transmitter delivers reliable, continuous monitoring. This rugged sensor converts vibration velocity into a 4-20 mA signal, seamlessly integrating with PLCs, DCS, and SCADA systems. Designed for maintenance engineers, it prioritizes ease of service and long-term accuracy.
Technical Specifications Breakdown
The 177230-00-01-05 offers a measurement range of 0 to 12.7 mm/s (0 to 0.5 in/s) with a frequency response of 10 Hz to 1 kHz (600 to 60 kcps) RMS. Its 4-20 mA current loop output provides a linear representation of peak vibration levels. The transmitter operates on an excitation voltage of 12 to 30 Vdc, current limited to 40 mA, and settles within 15 seconds to within 2% of final value. With a mounted resonant frequency greater than 12 kHz and transverse sensitivity less than 5%, it ensures accurate readings even in challenging conditions.
Industry Applications
This seismic transmitter excels in rotating machinery monitoring—pumps, fans, compressors, and turbines. In a petrochemical plant, for example, continuous vibration tracking helps detect bearing wear or imbalance early, preventing catastrophic failures. The 177230-00-01-05's hermetically sealed sensor and 316L stainless steel case withstand harsh environments, including 100% non-submerged humidity and temperatures from -40°C to +85°C (-40°F to +185°F).
Installation & Setup Guidance
Mount the 177230-00-01-05 using the 1/4-28 UNF hole or M6 x 1 SI / M8 x 1.25 SI threads, applying a torque of 4 to 7 N-m (35.4 to 62.0 in-lbf). The 3-pin MIL-C-5015 connector simplifies wiring: Pin A for 4-20 mA positive loop, Pin B for loop return and dynamic signal common, and Pin C for dynamic acceleration signal. Ensure the power supply is current limited (typical 30-35 mA) to protect the loop.
Maintenance & Reliability
For maintenance engineers, the 177230-00-01-05 minimizes service interruptions. Its ceramic/shear sensing element and hermetic seal resist contamination and moisture. Periodic inspection of the connector and mounting integrity is recommended. With no moving parts and a robust design, this transmitter offers long service life, reducing total cost of ownership.
Compatibility & Integration
The 4-20 mA output integrates directly with most PLC, DCS, and SCADA analog input modules. The 177230-00-01-05 requires no external signal conditioning, simplifying installation. Its electrical isolation exceeds 108 ohms, with an isolation breakdown voltage of 600 Vrms, ensuring reliable operation in electrically noisy environments.
