Bently Nevada 173186-01 Temperature Monitor | 3500 Series Machinery Protection System
Engineering Background
The Bently Nevada 3500 Series is the industry benchmark for continuous machinery protection in rotating equipment applications. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the 3500 platform provides real-time monitoring of critical machine parameters to prevent catastrophic failure and unplanned downtime.
Product Positioning
The Bently Nevada 173186-01 is a dedicated Temperature Monitor module within the 3500 rack-based system. It is engineered to accept thermocouple and RTD inputs, process temperature signals with high accuracy, and trigger protective relay outputs when user-defined alarm thresholds are exceeded. This module is the preferred choice for procurement engineers specifying temperature protection on turbines, compressors, pumps, and generators where API 670 compliance is required.

- Multi-Input Flexibility: Accepts both thermocouple and RTD sensor types within a single module, reducing spare-parts inventory complexity
- Rack-Integrated Architecture: Seamless integration with existing 3500 racks — no additional wiring infrastructure required
- Configurable Alarm Logic: Independent Alert and Danger setpoints per channel with latching/non-latching relay options
- High Channel Density: Maximizes rack slot utilization in space-constrained control rooms and skid-mounted panels
- Proven Field Reliability: Bently Nevada 3500 modules are deployed in tens of thousands of installations globally with documented MTBF exceeding 100,000 hours
System Architecture & Signal Flow
The 173186-01 installs into any available slot of a Bently Nevada 3500 rack alongside the System Monitor (3500/20) and I/O modules. Signal flow is as follows:
- Sensor Input: Thermocouple or RTD wired to the I/O module terminal block
- Signal Conditioning: Cold-junction compensation (thermocouple) or 4-wire resistance measurement (RTD) performed on-module
- Alarm Processing: Configurable Alert / Danger thresholds evaluated in real time; relay outputs activated on threshold breach
- Data Output: Processed temperature values transmitted over 3500 rack backplane to System Monitor for display, logging, and DCS/SCADA integration via Modbus or OPC
- Rack Communication: Full integration with Bently Nevada System 1 software for trend analysis, event logging, and predictive maintenance workflows

Technical FAQ
Q: Is the 173186-01 compatible with all 3500 rack configurations?
A: Yes. The module is designed for the standard 3500 rack backplane and is compatible with all 3500 Series rack sizes (4-slot, 7-slot, 14-slot).
Q: Can this module replace a 3500/60 in an existing installation?
A: The 173186-01 is the I/O module component of the 3500/60 Temperature Monitor. Confirm your existing rack configuration and firmware version before substitution. Contact our technical team for a compatibility assessment.
Q: What sensor types are supported?
A: The module supports J, K, T, E, R, S, and B type thermocouples, as well as Pt100 and Pt1000 RTDs in 2-wire, 3-wire, and 4-wire configurations.
Q: Is System 1 software required for operation?
A: No. The module operates standalone within the 3500 rack for protection functions. System 1 software is optional and used for advanced trending, diagnostics, and predictive maintenance.
Q: What is the lead time for in-stock units?
A: In-stock units typically ship within 1–3 business days. Contact us to confirm current availability.
