Product introduction

The Bently Nevada 3500/22-01-01-00 is an entry-level multi-channel temperature monitoring module, designed to deliver reliable temperature measurements for cost-sensitive industrial applications. As a streamlined alternative to the advanced 3500/22M, it focuses on essential temperature monitoring functions, making it ideal for non-critical machinery such as auxiliary pumps, fans, and small motors where high-precision measurements are not required.

This module complements basic vibration monitoring modules like the 3500/44-01-00, providing thermal data to controllers such as the 3500/53 133388-01. While it lacks the 3500/22M’s broad sensor compatibility and laboratory-grade accuracy, it offers a cost-effective solution for applications where tracking general temperature trends—rather than detecting subtle thermal anomalies—is sufficient.

Powered by stable supplies like the 3500/91 190782-01, the 3500/22-01-01-00 operates reliably in harsh industrial environments, from factory floors to outdoor equipment enclosures. Its compact design (occupying 1 rack slot) and simplified feature set make it easy to integrate into existing 3500 series systems, providing basic temperature protection without overcomplicating the monitoring setup.

Core advantages and technical highlights

Cost-effective temperature monitoring: The 3500/22-01-01-00 balances functionality and affordability, making it suitable for applications where high precision is unnecessary. With 4 channels supporting common sensor types (PT100 RTDs, Type K/J thermocouples), it covers most basic temperature monitoring needs—such as tracking motor bearing temperatures or process fluid temperatures—at a lower cost than the 3500/22M.

Compact design: Occupying just 1 rack slot (half the space of the 3500/22M), the module is ideal for space-constrained installations. This allows it to be paired with other 1-slot modules like the 3500/53 133388-01 controller, maximizing the number of monitoring points in small racks.

Simplified integration: Designed for easy setup, the 3500/22-01-01-00 works seamlessly with entry-level controllers like the 3500/53 133388-01, enabling basic temperature-vibration alarm logic. For example, it can trigger a warning via the 3500/60 when a motor’s bearing temperature exceeds 80°C and vibration from the 3500/44-01-00 exceeds 10 mm/s—providing essential protection without complex configuration.

Rugged reliability: Built to the same environmental standards as the 3500/22M (-40°C to +70°C operating range), the module maintains performance in extreme conditions. Its terminal blocks are protected against dust and moisture, ensuring reliable operation in dirty or humid environments like wastewater treatment plants or food processing facilities.

Comparison with 3500/22M

Typical application scenarios

In a municipal wastewater treatment plant, the 3500/22-01-01-00 monitors 4 submersible pump bearings using PT100 RTDs. Paired with the 3500/44-01-00 (vibration) and 3500/53 133388-01 (controller), it triggers a 3500/60 relay to shut down a pump if bearing temperature exceeds 85°C and vibration exceeds 12 mm/s—preventing motor burnout. Its compact size allows it to fit in a small rack alongside other modules, optimizing space in the plant’s control room.

At a food processing facility, the module tracks temperatures of 2 conveyor motor bearings (Type K thermocouples) and 2 process ovens (4-20 mA transmitters). The 3500/53 133388-01 uses its data to sound an alarm via the 3500/60 if oven temperature drops below 180°C (ensuring food safety) or motor temperature exceeds 90°C (preventing equipment failure). Its rugged design resists the washdown environment, while its simplicity reduces training needs for maintenance staff.

In a small manufacturing plant, the 3500/22-01-01-00 monitors a cooling tower fan’s motor and gearbox (PT100 RTDs). When paired with the 3500/44-01-00, it identifies a pattern: gearbox temperature rises 10°C above ambient and vibration increases at 1x rotational frequency—indicating lubrication loss. The 3500/53 133388-01 triggers a maintenance alert, allowing repairs during a scheduled shutdown to avoid unplanned downtime.

Installation, commissioning and maintenance instructions

Installation preparation: Mount the 3500/22-01-01-00 in a single slot of the 3500 rack, near the 3500/53 133388-01 controller for efficient data transfer. Power off the system via the 3500/91 190782-01 before installation. Secure with screws torqued to 0.6 Nm, verifying backplane alignment. Connect sensors to terminal blocks: RTDs use 2-wire or 3-wire connections (3-wire recommended for better accuracy), while thermocouples use matched extension wires to minimize errors.

Commissioning steps: Power on via the 3500/91 190782-01 and confirm all channel LEDs illuminate. Use 170180-01-00 software to configure each channel: set sensor type (e.g., “Type K thermocouple”), measurement range, and alarm thresholds (e.g., “Warning at 75°C, Danger at 90°C”). Calibrate using a portable temperature calibrator, verifying accuracy at key points (e.g., 0°C, 100°C). Test communication with the 3500/53 133388-01 by confirming temperature data appears in the controller’s interface.

Maintenance suggestions: Inspect quarterly, checking terminal block connections for tightness and corrosion—clean with a soft cloth and isopropyl alcohol if needed. Verify calibration annually using a NIST-traceable calibrator, adjusting via software if drift exceeds ±1.0°C. For thermocouple channels, inspect connections for oxidation semi-annually, as corroded joints introduce measurement errors. Update firmware annually to maintain compatibility with the 3500/53 133388-01 and 3500/44-01-00. Unlike the 3500/22M, no specialized tools are required for maintenance, simplifying upkeep.
