Bently Nevada 3500/61 163179-02 – Temperature Monitor | 3500 Series Machinery Protection Platform
Engineering Background
The Bently Nevada 3500 Series is the industry-standard modular machinery protection system deployed across power generation, oil & gas, petrochemical, and rotating equipment facilities worldwide. Developed and manufactured by Bently Nevada (a Baker Hughes company), the platform is engineered to API 670 standards and is trusted by OEMs and end-users for continuous, real-time machinery health monitoring.
Product Positioning
The 3500/61 (P/N 163179-02) is a dedicated Temperature Monitor module within the 3500 rack system. It acquires thermocouple or RTD signals from critical machine components—bearings, casings, stator windings—and provides configurable alarm and danger setpoints to protect rotating assets from thermal excursions. This module integrates seamlessly into existing 3500 racks without system downtime when hot-swap procedures are followed.

- Proven Field Reliability: Deployed in thousands of installations globally with documented MTBF exceeding 100,000 hours
System Architecture & Signal Flow
The 3500/61 module occupies a single slot in the 3500 rack chassis. Temperature sensors (TC or RTD) connect to the I/O module terminal block. Conditioned signals pass through the backplane to the 3500/61 monitor, which applies engineering-unit conversion, compares values against programmed setpoints, and drives relay outputs and system communication simultaneously. The rack’s Communication Gateway module (e.g., 3500/92) forwards data to DCS/SCADA via Modbus TCP or OPC.

Technical FAQ
Q: Is the 163179-02 revision compatible with all 3500 rack generations?
A: The 3500/61 is compatible with standard 3500 rack chassis. Confirm your rack’s backplane revision with Bently Nevada documentation or contact us for cross-reference support.
Q: Can this module accept both TC and RTD inputs simultaneously?
A: Input type is configured per channel via RCS software. Consult the 3500/61 datasheet (GEK-91485) for channel configuration rules.
Q: What is the lead time for this part?
A: In-stock units typically ship within 1–3 business days. Contact us to confirm current inventory status.
Q: Do you provide a test report or functional verification certificate?
A: Yes. A pre-shipment inspection report is available upon request at no additional charge.
Q: Is this a new or refurbished unit?
A: Units are clearly described as new surplus or tested-good refurbished. Condition is confirmed in your order confirmation.
