Bently Nevada 177230-02-01-CN Seismic Transmitter

Description

Engineered for continuous machinery vibration monitoring, the Bently Nevada 177230-02-01-CN is a high-performance seismic transmitter designed to measure casing vibration in industrial rotating equipment. This loop-powered, common-axis velocity transmitter provides a standard 4-to-20 mA output proportional to the overall vibration velocity. This output allows direct integration with Programmable Logic Controllers (PLCs), Distributed Control Systems (DCSs), and other process monitoring systems without requiring specialized monitoring monitors.

The unit features a robust 316L stainless steel casing and utilizes a 3-pin MIL-C-5015 connector, ensuring reliable performance in harsh, demanding industrial environments. The 177230-02-01-CN is factory-configured with specific scaling, frequency, and local approval designations to ensure compatibility with regional safety and technical requirements.

Features

• Direct Interface: Provides a 4-to-20 mA velocity output for straightforward integration with control systems (PLC/DCS).
• Rugged Design: Constructed with a 316L stainless steel housing for superior corrosion resistance and durability in harsh plant environments.
• Hermetic Seal: Employs a 3-pin MIL-C-5015 top connector, preventing moisture and dust ingress.
• Optimized Performance: Factory-configured frequency and range options provide accurate seismic casing measurements.

Applications

This seismic transmitter is suitable for a wide variety of industrial rotating machinery, including:

• Industrial fans and blowers
• Centrifugal and reciprocating pumps
• Air and process compressors
• Small-to-medium steam and gas turbines
• Electric motors and gearboxes

Installation Guidelines

• Mounting: Ensure the mounting surface is flat, clean, and free of paint to guarantee accurate transmission of high-frequency vibration signals. Torque the sensor to the manufacturer-specified values using a proper mounting stud.
• Cable Routing: Route the interface cable through protective conduit where mechanical damage or extreme fluid exposure is likely. Avoid routing adjacent to high-voltage power cables to prevent electromagnetic interference.
• Grounding: Ensure the transmitter casing is properly grounded to the machine frame. The cable shield should be grounded at the control system receiver side only to prevent ground loops.
