BENTLY NEVADA 136719-01 – Temperature Monitor Module for 3500 Series Machinery Protection

• Warranty: 365 days

• Delivery time: 1 week for in?stock; no more than one month at the latest

• Payment: 50% advance payment; full payment prior to delivery

• Express options: FedEx, UPS, DHL

• Multi-sensor support: Accepts common RTD and thermocouple inputs, so you can reuse existing probes on pumps, compressors, and turbines.

• Continuous protection: Real-time monitoring with configurable alarms helps catch bearing heating, seal degradation, or process upsets early.

• 3500 rack integration: Powered by the 3500 backplane and communicates through the 3500/22M TDI—no extra network card on the module.

• Channel-level diagnostics: Sensor OK checking and channel status help distinguish wiring faults from genuine temperature events.

• Flexible configuration: Per?channel input type selection, filtering, and alarm setpoints to match your plant standards.

• Service-friendly I/O: Rear I/O with removable terminals typically reduces downtime during probe replacement.

Typically used on bearing housings, motor windings, lube oil circuits, and seal areas where temperature rise is an early indicator of trouble. In refineries and petrochemical plants it seems to be a favorite for critical pumps and compressors. Power generation users often pair it with vibration monitors to protect steam and gas turbines. I’ve also seen it on paper machine dryer cans and large HVAC chillers where trending helps plan shutdown windows.

• Reliability: Designed for continuous duty in the 3500 platform—stable, predictable behavior under plant conditions.

• Compatibility: Works with standard RTD/TC types and the wider 3500 ecosystem (3500/22M TDI, 3500/33 Relay, 3500/15 Power Supply).

• Cost savings: Reuses existing sensors and wiring in many cases; reduces nuisance trips with proper OK checking and alarm filtering.

• Supportability: Configuration and diagnostics through familiar 3500 toolsets simplify commissioning and audits.

A maintenance lead at a fertilizer plant put it simply: “We added temperature channels on three hot-running pumps. The early warning averted two unplanned outages in the first quarter.”

• Panel & environment: Install in a standard 3500 rack within a clean, ventilated cabinet. Keep ambient within the specified range and allow airflow around the rack.

• Wiring: Use shielded cable for thermocouples; maintain proper polarity. For RTDs, match 2- or 3?wire configuration and keep lead lengths consistent for accuracy.

• Grounding & noise: Single-point ground and correct shield termination reduce drift and spurious alarms.

• Safety: De-energize the rack slot before inserting or removing modules. Verify sensor circuits are de-energized in classified areas.

• Routine care: Periodically verify channel calibration against a known reference, clean terminals, check tightness, and review alarm setpoints during outages.

• Firmware/Config: Keep module configuration backed up; coordinate firmware compatibility with the 3500/22M TDI to avoid mismatches.

• Manufactured to industrial quality standards; CE compliant

• Typically meets RoHS; UL/CSA certifications available on the 3500 platform

• Manufacturer warranty practices apply; our supply warranty is 365 days as stated above

One thing I appreciate is how seamlessly the 136719-01 drops into mixed racks—vibration on one slot, temperature on the next—so you can expand protection without redesigning the cabinet. If you’d like, we can also supply complementary modules such as 3500/22M TDI, 3500/33 Relay, and 3500/15 Power Supply to round out the build.
