3500/60 Temperature Monitor
Overview
The bently nevada 3500/60 Temperature Monitor integrates temperature protection into the Bently Nevada 3500 machinery protection rack. By conditioning RTD/TC signals and converting them to engineering units, it drives alarm logic for trips/interlocks and supplies high-quality data to System 1 so you can correlate heat with vibration, process changes, and machine state.
Measurements & Inputs
Sensor types: Common RTD (e.g., Pt100; 2/3/4-wire) and TC (Type K/J/E/T, etc.)
Engineering units: °C/°F with linearization and scaling
Per-channel setup: Range, filtering, and alarm strategy are independently configurable
Protection & Alarming
Programmable Alert/Danger thresholds with delays and latching options
Time-stamped events to the rack—tie to relay logic for shutdowns/interlocks
Designed to complement API-class protection philosophies alongside vibration monitors
Diagnostics & System 1
Publishes temperature trends to System 1 (via rack interface, e.g., 3500/22M TDI)
Correlate temperature with vibration/phase/process for faster root-cause analysis
Supports reports, alarms history, and maintenance planning
Integration & Operation
Hot-swappable monitor; front LEDs indicate OK/fault/alarm
Configured via 3500 Rack Configuration Software; remote work through System 1 per site standard
Works with existing 3500 monitors (40M/42M/44M, etc.) in mixed racks
Compatibility & Ordering Notes
Confirm sensor model, wiring (RTD 3/4-wire preferred), ranges, and ambient conditions
Share rack BOM/slot map and System 1 version to verify compatibility
Provide cable lengths and termination details to avoid measurement drift/noise
Typical Applications
Bearing and housing temperature on turbines, compressors, large motors/generators
Lube-oil and coolant circuits monitoring
Seal and case temperature protection in critical rotating assets

Technical Overview
The Bently Nevada 3500/60 Temperature Monitor is a rack-mounted module within the Bently Nevada (Baker Hughes) 3500 Series Machinery Protection System, providing continuous temperature monitoring for bearing, casing, and process temperature points on critical rotating machinery. Per Baker Hughes’ official datasheet (Doc #141540), each 3500/60 module accepts up to 6 channels of temperature input, supporting a wide range of transducer types: thermocouples (Type E, J, K, and T) and RTDs, including 100Ω 3-/4-wire platinum (both α=0.00385 and α=0.00392 standards), 120Ω 3-/4-wire nickel, and 10Ω 3-/4-wire copper elements, with input impedance of 10 MΩ per lead.
Two module families are available: a non-isolated RTD/TC version supporting mixed input types on the same module, and a TC-isolated version providing 500 Vdc system isolation and 250 Vdc channel-to-channel isolation for applications requiring galvanic separation between measurement points. Rather than dedicated onboard relay contacts, the 3500/60 provides software-configurable Alert and Danger setpoints across 0–100% of full scale, with an accuracy within 0.13% of setpoint and independently adjustable time delays (Alert: 1–60 seconds in 1-second steps; Danger: 1–60 seconds in 0.5-second steps). A key distinction from its sister module, the 3500/61, is that the /60 has no per-channel 4–20 mA recorder output — the /61 adds this feature while remaining otherwise functionally identical.
The module communicates with the rest of the 3500 rack over the system backplane and is configured using Bently Nevada’s 3500 Rack Configuration Software. It supports Triple Modular Redundant (TMR) operation, in which three adjacent monitors vote two-out-of-three on a measurement, for safety-instrumented and high-integrity shutdown applications. Power consumption is 7 watts nominal. Operating temperature range is −30°C to +65°C (0°C to +65°C when internal-barrier I/O modules are fitted), with storage from −40°C to +85°C. The module measures 241.3 × 24.4 × 241.8 mm and weighs approximately 0.91 kg.
Compliance and Certifications
The 3500/60 is designed to SIL 2 functional safety requirements and complies with EN 61000-6-2/-4 for EMC immunity and emissions, EN 61010-1 for electrical safety, and RoHS Directive 2011/65/EU. It is designed with IEC 62443 cybersecurity principles in mind and carries hazardous-area approvals for Class I, Division 2, Groups A-D and Class I, Zone 2 (ATEX/IECEx Ex nA/ec nC ic IIC T4 Gc ratings, some configurations pending approval per the manufacturer’s documentation). The module also meets DNV GL and ABS marine classification society rules, and is FCC Part 15 compliant.
Applications
The 3500/60 is deployed within Bently Nevada 3500 racks to continuously monitor bearing, casing, and process temperatures on turbines, compressors, and pumps in oil and gas, petrochemical, and power generation facilities, feeding both operator displays and automated protective shutdown logic as part of a complete machinery protection system.
