Bently Nevada 190501-13-99-00 Velomitor CT Replacement

Product Overview

Bently Nevada 190501-13-99-00 Velomitor CT Replacement: Seamless Upgrade for Legacy Vibration Monitoring Systems

The Bently Nevada 190501-13-99-00 is a Velomitor CT Series piezo-velocity transducer designed for continuous vibration monitoring of rotating machinery in oil & gas, power generation, petrochemical, and heavy industrial environments. Supplied with a 13-metre integral cable, this unit delivers a broadband velocity output (mV/mm/s) that interfaces directly with Bently Nevada 3500 Series rack-based monitoring systems — including the 3500/42M Proximitor/Seismic Monitor module — without requiring signal conditioning adapters or firmware changes.

For plants running legacy Bently Nevada 3300 Series or early-generation 3500 Series racks, the 190501-13-99-00 is the authorised drop-in replacement for discontinued Velomitor models such as the 330500 and 330525 velocity transducers. The mechanical footprint, M8 mounting thread, and connector pinout are preserved, meaning field technicians can complete a like-for-like swap during a planned outage window without re-routing conduit or modifying the junction box wiring.

Seamless Upgrade Solutions

A successful migration from a legacy vibration monitoring architecture to a current-generation Bently Nevada platform typically involves more than a single transducer swap. When upgrading from a 3300 Series rack to a 3500 Series rack, engineers commonly replace the 3500/20 Rack Interface Module (RIM) and the 3500/15 Power Supply in the same outage window to eliminate single points of failure. If the plant is also modernising its communication backbone, the 3500/92 Communication Gateway Module enables Modbus TCP or OPC-UA connectivity to a DCS or SCADA layer without replacing the entire rack.

For machinery trains that include both radial and axial measurement points, the 190501-13-99-00 velocity transducer is frequently installed alongside Bently Nevada 330180 or 330130 proximity probes and driver assemblies to provide a complete vibration signature — covering both seismic velocity and shaft displacement — on a single 3500/42M monitor card. This dual-measurement approach is standard practice for API 670-compliant installations on steam turbines, compressors, and large pumps.

Where the existing field wiring uses older 3300/20 barrier terminal blocks, these can typically be reused with the 190501-13-99-00 without re-termination, provided the cable screen is correctly bonded at the rack end. If the plant is simultaneously upgrading its I/O infrastructure, Bently Nevada 3500/40M Proximitor Monitor modules and 3500/50 Tachometer modules are compatible rack neighbours and can be installed in the same 19-inch chassis without additional power derating.

For sites migrating from a standalone vibration analyser to a fully integrated condition monitoring platform, the System 1 software suite (formerly Bently Nevada System 1 Evolution) communicates natively with the 3500 rack via the 3500/92 gateway, enabling trend logging, alarm management, and predictive maintenance analytics without additional signal converters or protocol bridges.

Retrofit Guidance FAQ

Q: Can I reuse the existing field cable when replacing a 330500 with the 190501-13-99-00?
A: The 190501-13-99-00 ships with a 13 m integral cable. If your existing conduit run is shorter, the surplus cable can be coiled inside the junction box. The connector pinout is identical to the 330500, so no re-termination at the monitor rack is required.

Q: Will the 3500/42M module require reconfiguration after the swap?
A: No. Because the output sensitivity (100 mV/in/s) and supply voltage range are identical, the existing channel configuration in the Rack Configuration Software (RCS) remains valid. A channel bypass and restore during installation is sufficient; no full recalibration is needed.

Q: Is the 190501-13-99-00 compatible with 3300 Series monitors?
A: Yes. The analogue output is fully compatible with 3300/16 and 3300/20 velocity monitor cards. Verify the OK relay threshold settings in the monitor after installation.

Q: What is the physical installation clearance requirement?
A: The Velomitor CT body diameter is 22 mm with a 35 mm hex flat. Standard M8 mounting boss clearance of 50 mm axial depth is sufficient. No additional bracket or adapter is required for direct replacement of 330500/330525 units.

Q: How do I verify correct operation after installation?
A: With the machine at rest, confirm the bias voltage at the monitor input is within the OK window (typically −2 VDC to −18 VDC depending on cable length). During run-up, verify the velocity reading is within expected baseline values for the machine train. Use the 3500 Rack Configuration Software to confirm no latched alerts are present.
