Turbine Temperature Monitoring Solution — Bently Nevada 3500/60 163179-01 | 3500 Series
In power generation and petrochemical facilities, undetected bearing overtemperature is the leading cause of catastrophic turbine failure. Industry data shows that over 60% of rotating machinery failures are preceded by abnormal temperature excursions lasting less than 90 seconds — a window too narrow for manual inspection. A single unplanned turbine outage costs operators between $500,000 and $2,000,000 USD per day in lost generation capacity, emergency maintenance, and regulatory penalties. Plants running legacy thermocouple readouts without dedicated monitoring modules face MTTR (Mean Time to Repair) figures 3× higher than facilities with integrated condition monitoring.
The Bently Nevada 3500/60 163179-01 Temperature Monitor is purpose-engineered to close this gap. As a native module within the 3500 Series machinery protection rack, it acquires, conditions, and processes thermocouple and RTD signals in real time — triggering alarm and trip outputs within milliseconds of a threshold breach. By integrating directly with the 3500 rack backplane, it eliminates signal conversion latency and provides a single, auditable data path from sensor to DCS/SCADA, enabling engineers to act before damage propagates.
Where This Product Is Used
Power Generation — Steam & Gas Turbines
Monitors bearing metal temperature (BMT) and exhaust gas temperature (EGT) on GE Frame 7/9, Siemens SGT, and Mitsubishi M501 turbines. Typical operating range: −40 °C to +125 °C ambient rack environment; sensor inputs up to 1,372 °C (Type K TC).

Oil & Gas — Compressor Trains
Deployed on centrifugal and reciprocating compressor packages (Dresser-Rand, MAN, Ariel) for interstage cooler outlet temperature and lube oil temperature monitoring. Hazardous area installations use IS barriers per IEC 60079-11; module supports HART-transparent signal paths for remote calibration without process interruption.
Petrochemical — Reactor & Pump Systems
Used in ethylene cracker hot-gas expanders and boiler feed pump trains where process fluid temperatures exceed 300 °C. Integrates with Emerson DeltaV and Honeywell Experion PKS via Modbus RTU or 4–20 mA hardwired outputs. Meets API 670 5th Edition mandatory instrumentation requirements for critical machinery.

Application-Specific FAQ
Q: Can the 3500/60 163179-01 be used for gas turbine exhaust temperature monitoring in a combined-cycle power plant?
A: Yes. The module accepts Type K and Type R thermocouples rated to 1,372 °C and 1,600 °C respectively, covering typical gas turbine EGT ranges of 500–650 °C. It integrates with the 3500 rack to provide alarm and trip outputs to the turbine control system (TCS) within API 670-compliant response times. Ensure the rack RIM is configured for your DCS communication protocol (Modbus RTU or Ethernet).
Q: Is this module suitable for ATEX Zone 1 compressor bearing temperature monitoring on an offshore platform?
A: The 3500/60 163179-01 carries ATEX Zone 2 certification for the module itself. For Zone 1 sensor installations, IS barriers or galvanic isolators (e.g., MTL 787+, P+F KFD2-series) must be installed between the field sensor and the module input terminals. This configuration is standard practice for offshore API 670 installations and does not affect module measurement accuracy.
Q: What is the replacement and cross-reference path if the 163179-01 is discontinued or unavailable?
A: Baker Hughes (Bently Nevada) has introduced the 3500/60 with updated firmware revisions under the same base part number family. Functionally equivalent replacements include the 163179-02 (revised firmware) and the 3500/60M for applications requiring Modbus-native output. Konmask.com maintains stock of multiple revisions; specify your rack firmware version when inquiring to ensure backplane compatibility.
