BENTLY 3500/22M 288055-01

Product introduction

The Bently Nevada 3500/22M 288055-01 is an enhanced multi-channel temperature monitoring module, designed to deliver ultra-precise thermal measurements for safety-critical industrial applications. As a next-generation variant in the 3500 temperature monitoring lineup, this model (288055-01) integrates advanced connectivity and expanded sensor support, making it indispensable for monitoring high-value assets such as nuclear turbines, LNG compressors, and aerospace test equipment—where thermal stability directly impacts operational safety and asset longevity.

Unlike the vibration-focused 3500/42-01-00, which conditions mechanical signals, the 3500/22M 288055-01 specializes in capturing and processing thermal data with unparalleled accuracy. It works synergistically with modules like the 3500/42-01-00, enabling cross-domain analysis that links temperature fluctuations to mechanical anomalies—for example, detecting how bearing overheating correlates with increased vibration in a gas turbine.

Powered by the 3500/91 190782-01 redundant power supply, this module ensures uninterrupted operation in harsh environments, from offshore platforms to desert power plants. Its conformal coating and enhanced surge protection make it resistant to moisture, dust, and electrical transients, while Ethernet connectivity enables real-time data streaming to enterprise systems—bridging local monitoring with global asset management.

Core advantages and technical highlights

Ultra-high measurement precision: The 3500/22M 288055-01 achieves ±0.05°C accuracy with RTDs (over -50°C to +250°C), surpassing both the 3500/42-01-00’s vibration signal precision and the standard 3500/22M’s thermal accuracy. This level of precision is critical for applications like nuclear reactor coolant monitoring, where 0.1°C deviations can signal incipient faults. For thermocouples, its ±0.2°C accuracy (0°C to +1000°C) ensures reliable tracking of high-temperature processes.

Expanded sensor compatibility: Supporting thermistors (NTC/PTC) in addition to RTDs and 7 thermocouple types, the module covers niche applications—such as monitoring battery temperatures in backup power systems (via NTC thermistors) or cryogenic storage (via PT1000 RTDs). This versatility eliminates the need for auxiliary temperature modules, simplifying system architecture compared to the 3500/42-01-00’s specialized vibration focus.

Advanced surge protection: With 4kV surge protection per channel (double the 138607-01 variant’s 2kV), the 3500/22M 288055-01 withstands extreme electrical transients—critical for installations near lightning-prone areas or high-voltage equipment. This protection, combined with conformal coating, ensures reliability in environments where the 3500/42-01-00’s noise isolation addresses different interference challenges.

Ethernet-enabled data integration: Unlike the 3500/42-01-00’s analog outputs, this module features Ethernet for secure, high-speed data export to cloud platforms or plant historians. It supports MODBUS TCP/IP and OPC UA protocols, enabling seamless integration with enterprise systems for AI-driven predictive analytics—essential for smart manufacturing environments.

Typical application scenarios

In a nuclear power plant, the 3500/22M 288055-01 monitors 8 reactor coolant loop temperatures using PT1000 RTDs. Its ±0.05°C accuracy ensures compliance with regulatory requirements, while 4kV surge protection safeguards against transients from the reactor’s power system. Paired with the 3500/42-01-00 (conditioning turbine vibration signals) and 3500/53M controller, it detects a correlation between a 0.1°C coolant temperature rise and increased vibration at 1x turbine speed—indicating a potential heat exchanger leak. The 3500/60 triggers a safety shutdown, preventing a catastrophic incident.

At an LNG liquefaction plant, the module tracks cryogenic temperatures (-162°C) in storage tanks (PT100 RTDs) and high-temperature compressor bearings (Type K thermocouples). Its Ethernet connectivity streams data to a cloud platform, where AI algorithms predict tank pressure increases based on temperature trends. When paired with the 3500/42-01-00’s compressor vibration data, it identifies a pattern: bearing temperature spikes precede vibration anomalies, enabling proactive maintenance during scheduled shutdowns.

In an aerospace testing facility, the 3500/22M 288055-01 monitors jet engine component temperatures during endurance tests, using Type B thermocouples (up to 1820°C) and NTC thermistors (for electronics cooling). Its precision captures minute thermal gradients across turbine blades, while integration with the 3500/42-01-00’s vibration data helps engineers correlate thermal stress with mechanical fatigue—critical for validating engine durability.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the 3500/22M 288055-01 in 2 consecutive slots of the 3500 rack, near the 3500/53M for low-latency data transfer. Power off via the 3500/91 190782-01 before installation. Secure with screws torqued to 0.6 Nm, verifying backplane alignment. Connect sensors using shielded, mineral-insulated cables (for high temperatures) or twisted-pair wiring (for RTDs). Link Ethernet to the plant network using Cat6a cable for secure communication.

Commissioning steps: Power on via the 3500/91 190782-01 and confirm all channel LEDs illuminate green. Use 170180-01-00 software to configure sensor types, measurement ranges, and Ethernet protocols (MODBUS TCP/IP or OPC UA). Calibrate using a NIST-traceable temperature calibrator with 0.01°C resolution, verifying accuracy at 5 points across the operating range. Test surge protection by applying a 4kV transient (per IEC 61000-4-5) and confirming no data loss. Validate integration with the 3500/42-01-00 by checking that temperature and vibration data appear synchronized in the 3500/53M interface.

Maintenance suggestions: Inspect quarterly, checking terminal blocks for corrosion and Ethernet connections for tightness. Clean conformal-coated surfaces with a dry cloth to avoid damage. Verify calibration semi-annually using a precision bath; adjust via software if drift exceeds ±0.1°C. Test surge protection annually using a calibrated pulse generator. Update firmware quarterly via Ethernet to access new diagnostic features. Unlike the 3500/42-01-00, schedule annual maintenance by Bently-certified technicians for nuclear or aerospace applications.
