Description
Product Introduction & Engineering Value
Temperature problems rarely appear without warning. Bearing metal temperatures rise, winding insulation degrades, and lubrication conditions change before a major equipment event occurs. The Bently Nevada 163179-02 provides continuous temperature monitoring to help engineers identify abnormal thermal behavior in critical machinery.
Installed in a 3500 rack, this module accepts RTD and thermocouple signals, processes measured values, and compares them against configurable alarm limits. The additional recorder outputs make it suitable for applications requiring external trending through DCS, PLC, or historian systems.

Field Application & The “Trench” Experience
A power station maintenance team supporting a steam turbine noticed a gradual increase in bearing temperature alarms during startup cycles. The operators initially suspected lubrication issues because the temperature rise appeared only under specific operating conditions.
The instrumentation group reviewed sensor wiring, RTD resistance values, and DCS temperature trends. Field measurements confirmed the sensors were operating correctly, but the existing temperature monitor module was producing inconsistent channel behavior.
The team replaced the aging Bently Nevada 163179-02 3500/61 Temperature Monitor Module, restored the existing configuration, and verified all six temperature channels against field references. The turbine monitoring system returned to stable operation without changes to the existing protection architecture.
Typical application scenarios include:
- Steam turbine bearing temperature monitoring
- Gas turbine casing temperature measurement
- Generator winding thermal protection
- Compressor and pump temperature surveillance systems

Transparency SOP: QA & Testing
Temperature monitoring modules require verification of both signal processing and alarm behavior.
Inspection and test sequence:
1. Identification review
- Confirm Bently Nevada label
- Verify 163179-02 part number
- Check module revision information
- Inspect front panel indicators
2. Electrical testing
- Verify rack power-up response
- Check module diagnostics
- Confirm backplane communication
- Inspect connector condition
3. Temperature signal validation
- Simulate RTD or TC inputs when test equipment is available
- Verify channel measurement response
- Check alarm setpoint operation
- Confirm recorder output behavior
Testing documentation should be maintained with the spare unit for future maintenance reference.
The Veteran’s Tech Trap Guide
⚠️ Do not overlook the I/O module match.
The 163179-02 monitor module works with specific rear I/O configurations. The installed I/O module type must match the replacement setup.
⚠️ A temperature alarm does not always mean a bad monitor.
Check sensor calibration, RTD wiring resistance, thermocouple polarity, and terminal connections before replacing the module.
⚠️ Recorder outputs need correct loop design.
The 3500/61 provides channel recorder outputs. Incorrect wiring to DCS or PLC analog inputs can create misleading readings.
PRO TIP: Before replacement, save the 3500 configuration file and record each channel’s sensor type, alarm limits, and scaling parameters.
Dynamic FAQ
Q1. What is the Bently Nevada 163179-02 used for?
The 163179-02 is a 3500/61 Temperature Monitor Module used for six-channel temperature monitoring in Bently Nevada 3500 machinery protection systems.
Q2. How many temperature channels does the 163179-02 support?
The module supports six independent temperature monitoring channels.
Q3. What sensors can be connected to the 163179-02?
The module accepts RTD and thermocouple temperature inputs depending on the installed I/O configuration.
Q4. What is the difference between 3500/60 and 3500/61?
Both provide six-channel temperature monitoring. The 3500/61 version adds recorder outputs for each channel, allowing external temperature data transmission.
Q5. Can 163179-02 directly replace another 3500 temperature module?
Replacement depends on I/O module type, rack configuration, firmware compatibility, and existing temperature sensor wiring.
Q6. Is Bently Nevada 163179-02 available as new surplus?
Availability depends on inventory. Suppliers may provide new surplus, tested used, or refurbished 3500 Series temperature monitoring modules.
Q7. How should a refurbished 163179-02 be tested?
Recommended testing includes visual inspection, rack power verification, temperature input simulation, alarm testing, communication checks, and recorder output validation where applicable.
Q8. What warranty is normally provided?
Warranty coverage depends on supplier condition classification. New surplus and refurbished Bently Nevada modules generally have different warranty terms that should be confirmed before purchase.
