Bently Nevada 350900HTVAS-A0-B4 Probe Connection Cable – High‑Temperature Lead for Proximity/Vibration Sensing

The Bently Nevada 350900HTVAS-A0-B4 is a high‑temperature probe connection cable designed for robust, low‑noise signal transmission between Bently Nevada proximity or vibration sensors and their associated drivers/monitors. It’s typically used around hot machinery zones where standard cabling struggles, helping preserve signal integrity for reliable condition monitoring. From my experience, it suits retrofit and OEM builds alike when you need stable measurements under heat, oil mist, and vibration.

• High‑temperature construction – Built for elevated ambient conditions; the HT series is typically used up to around 200°C zones depending on routing and proximity to heat sources.

• Low‑noise, shielded signal path – Coaxial architecture helps minimize electromagnetic interference, preserving proximity or vibration signal fidelity back to the monitor.

• Series compatibility – Designed for Bently Nevada probe/sensor systems and monitors (commonly used with 3300/3300 XL/3500 platforms), reducing mismatch risks during upgrades.

• Ruggedized jacket options – The code pattern indicates armor/jacket variants; in many cases this includes chemical‑resistant and abrasion‑resistant outer layers for harsh areas.

• Consistent impedance control – Stable cable characteristics support accurate gap/vibration readings and repeatable calibration results.

• Option‑coded length – The “A0‑B4” suffix denotes ordering options such as length and build; it seems to be a mid‑length variant suited for most pump, fan, and gearbox layouts.

Common in high‑temperature or semi‑enclosed equipment bays where vibration and proximity signals must remain stable: steam/gas turbines (bearing and seal zones), refinery and petrochemical pumps, hot‑end fans/blowers, compressors, gearboxes, and paper/steel mill rotating assets. You might notice this cable specified when the monitor is cabinet‑mounted while the probe sits close to a hot bearing housing or casing.

• Reliability in heat – Reduces drift and intermittent faults that often show up with generic cabling near hot machines.

• Compatibility – Mates with Bently Nevada probe/monitor ecosystems, which typically shortens commissioning time.

• Noise immunity – Shielding and consistent impedance help maintain a clean signal, supporting tighter alarm settings and fewer nuisance trips.

• Lower lifecycle cost – Durable jacket and proper strain relief usually mean fewer unplanned cable swaps.

• Supportability – Clear option coding (like A0‑B4) simplifies re‑ordering and spares standardization across units.

One thing I appreciate is how maintenance teams report fewer “mystery” spikes after replacing mixed third‑party leads with this series. It’s not magic—just better shielding and correct matching to the monitor input.

• Routing – Keep away from high‑energy power cables, VFD outputs, and hot surfaces when possible. Use conduit or metallic glands in hazardous areas per site standards.

• Bend radius – Maintain a generous minimum bend radius (typically ≥10× cable OD) to avoid conductor/jacket damage.

• Grounding & shielding – Terminate shields per Bently Nevada guidelines to prevent ground loops and preserve low‑noise performance.

• Connector handling – Do not over‑tighten; inspect mating connectors for contamination, oil ingress, or bent pins. Replace worn locking hardware.

• Cabinet practices – Provide strain relief at entry points; separate sensor leads from power and network wiring inside panels.

• Routine checks – Visual inspection during outages, continuity check if readings drift, and verify monitor calibration after any cable replacement.

• Firmware & settings – When cables are changed or rerouted, reconfirm proximitor/monitor configuration and any filtering in the 3500/other platform.

• Compliance – Typically produced under ISO 9001 quality systems; RoHS compliant materials in most cases.

• CE/UL – Cables are generally supplied for use within CE/UL‑compliant systems; specific listings depend on final installation.

• Warranty – Standard manufacturer warranty is commonly 1 year against defects when installed per guidelines.

If you’d like, share your required length, connector mating models (probe/driver or monitor part numbers), and ambient temperature range. I can verify the 350900HTVAS-A0-B4 fit or recommend the closest build option so you don’t chase noise or compatibility issues later.
