Technical Specifications

This sensor is a “dual-output” device, capturing mechanical vibration and thermal data through a single mounting point.

Integration: Triconex and Trendmaster Pro

In a high-availability environment (like a refinery or power plant), the Triconex system handles the Safety (Shutdown) logic, while the Trendmaster Pro (using the 1600071-001) handles the Condition Monitoring (Predictive Maintenance).

1. The Distributed Bus Architecture

The 1600071-001 sensors do not wire back to the Triconex main chassis. Instead, they connect to a TIM (Transducer Interface Module). Multiple TIMs are daisy-chained together on a single digital bus, which eventually feeds data into a Triconex Communications Module (TCM) or a dedicated gateway for display on the DCS/HMI.

2. Why Use This Sensor with Triconex?

• Asset Protection: While the Triconex 3008 or 3009 processors focus on “Is the machine safe to run?”, the 1600071-001 answers “How long until this bearing fails?”
• Cost Efficiency: By using the Trendmaster “bus” approach, you can monitor hundreds of auxiliary motors and pumps surrounding the Triconex-protected main turbine without running miles of individual shielded cables.

Engineering Insights: Best Practices

1. Mounting and Frequency Response

To capture the high-frequency vibration (up to 10 kHz) necessary to detect early-stage bearing flaking:

• Requirement: The sensor must be stud-mounted. Avoid using magnetic bases for permanent installations, as they act as a “low-pass filter” and will cut off the high-frequency data the 1600071-001 is designed to provide.
• Tip: Use a torque wrench to tighten the sensor to 3.4 to 4.5 N·m (30–40 in-lb). Over-tightening can damage the internal piezo-element.

2. Environmental Sealing

The M12 connector is the most vulnerable point.

• Best Practice: Even though the sensor is stainless steel, use a boot or weather-shield over the M12 connector if the sensor is located outdoors or near wash-down areas. Moisture ingress into the connector pins is the #1 cause of “Sensor Fault” errors in Trendmaster systems.

3. Data Interpretation (Vibration vs. Temperature)

When analyzing data from the 1600071-001:

• Vibration usually increases weeks before a failure.
• Temperature usually increases hours before a failure.If both variables show a sharp upward trend, a catastrophic failure is imminent, and the Triconex system should be prepared for a manual or automated shutdown sequence.

FAQ

Q: Is the 1600071-001 Intrinsicly Safe (IS)?

A: Yes, when used with the appropriate Bently Nevada/Triconex barriers or TIMs, it is rated for hazardous areas (Class I, Div 1/Zone 0).

Q: Can I replace just the cable if it’s damaged?

A: Yes. Since the sensor uses a standard M12 4-pin connector, the cable is a separate assembly. Ensure the replacement cable is high-temp rated if it is running along a motor casing.

Q: How often does the sensor “report” to the Triconex system?

A: In a Trendmaster Pro system, sensors are polled sequentially. Depending on how many sensors are on the bus, the update time might range from every 30 seconds to several minutes. This is why it is for trending, not instantaneous tripping.
