Product Overview
The Bently Nevada 177230-00-01-05 is a rugged seismic transmitter engineered for continuous vibration monitoring in demanding industrial environments. This Industrial Automation Module delivers a 4-20 mA current loop output proportional to peak vibration levels, making it an essential component for predictive maintenance programs.
With a compact 25.4 mm diameter and 66.0 mm height, the 177230-00-01-05 fits easily into tight machinery spaces. Its 316L stainless steel case and connector ensure corrosion resistance in harsh conditions, while the hermetically sealed sensor protects internal components from moisture and contaminants.
Key Technical Specifications
The 177230-00-01-05 provides reliable, accurate vibration data with these core specifications:
-
Measurement Range: 0–12.7 mm/s (0–0.5 in/s) RMS
-
Frequency Response: 10 Hz to 1 kHz (600 to 60 kcps) RMS
-
Output Signal: 4–20 mA current loop (Pin A to Pin B)
-
Excitation Voltage: 12 to 30 Vdc (current limited to 40 mA)
-
Operating Temperature: -40°C to +85°C (-40°F to +185°F)
-
Case Material: 316L stainless steel
-
Mounting Threads: ¼-28 UNF, M6 x 1 SI, M8 x 1.25 SI
-
Approvals: CSA/NRTL/C, ATEX/IECEx
The transmitter's settling time is less than 15 seconds within 2% of final value, ensuring rapid response to changing vibration conditions. Its mounted resonant frequency exceeds 12 kHz, minimizing interference from structural resonances.
Performance and Reliability
This Bently Nevada 177230-00-01-05 seismic transmitter uses a ceramic shear sensing element, providing stable and repeatable measurements. Transverse sensitivity is less than 5% of the main axis sensitivity, ensuring accurate readings even in multi-directional vibration environments.
Electrical isolation is greater than 10^8 ohms, with an isolation breakdown voltage of 600 Vrms at less than 1 mA leakage current. This robust isolation protects downstream PLC, DCS, and SCADA systems from electrical noise and transients.
Industry Applications
The 177230-00-01-05 is ideal for vibration monitoring on rotating equipment such as pumps, fans, compressors, and motors. Its 4-20 mA output interfaces directly with most industrial control systems, enabling real-time condition monitoring and alarm annunciation.
In petrochemical plants, the ATEX/IECEx approvals allow installation in hazardous areas. The transmitter's 100% non-submerged relative humidity rating makes it suitable for wash-down environments common in food and beverage processing.
Installation and Setup
Mount the 177230-00-01-05 using the ¼-28 UNF mounting hole or optional M6/M8 threads. Apply a mounting torque of 4 to 7 N-m (35.4 to 62.0 in-lbf) to ensure a secure, reliable connection.
Wire the 3-pin MIL-C-5015 connector as follows: Pin A connects to the 4-20 mA positive loop, Pin B to the loop return (common for dynamic signal), and Pin C provides an unbuffered dynamic acceleration signal referenced to Pin B. Ensure the power supply is current-limited to 30–35 mA as typical for PLC/DCS internal supplies.
Maintenance and Longevity
The hermetically sealed design of the 177230-00-01-05 requires minimal maintenance. Regularly inspect the connector for moisture ingress and verify the mounting torque periodically, especially in high-vibration applications.
With its 316L stainless steel construction and robust electrical specifications, this transmitter offers long-term reliability, reducing downtime and maintenance costs.
Selection Guide
When selecting the 177230-00-01-05, verify your system's excitation voltage (12-30 Vdc) and current limit (40 mA max) to ensure compatibility. Confirm the required frequency response and measurement range for your application.
