Product Overview

The PREDICTECH TM301-A02-B00-C01-D00-E00-F00-G00 is a specialized Shaft Vibration Transmitter designed for critical machinery protection applications. This compact device processes the raw signal from an eddy current proximity probe into a usable 4-20 mA current output, enabling easy integration with PLC or DCS systems. The inclusion of the C01 configuration adds a crucial single solid-state relay output, enhancing the unit's capabilities by providing immediate local alerts or control actions. The TM301 serves as a cost-effective, standalone monitoring solution for vital rotating machinery, offering a powerful yet economical approach to machinery protection and predictive maintenance.

Technical Data

The TM301-A02-B00-C01 is engineered to meet the high-precision requirements of API 670 shaft vibration measurement. The A02 configuration ensures the device processes radial shaft vibration or displacement accurately, while the C01 code activates the integrated alarm relay. This relay allows for immediate actions, such as triggering a shutdown or activating a warning light when vibration exceeds preset limits. The transmitter’s robust, compact design is optimized for DIN rail mounting inside control cabinets, ensuring reliable performance in demanding industrial environments.

Parameters

Typical Applications

The TM301-A02-B00-C01 transmitter is essential for continuous monitoring and protection of mid-critical rotating machinery, where immediate local alerts are required. It is commonly applied in environments such as utility plants, paper mills, and steel manufacturing. For example, the TM301-C01 is ideal for monitoring the main bearings on large industrial fans, blowers, or centrifugal pumps. The integrated alarm relay can trigger machine shutdowns or activate external warning lights when vibration exceeds predefined thresholds. This dual-protection system, combining both the 4-20 mA output and the relay functionality, ensures comprehensive protection of vital machinery.

Frequently Asked Questions (FAQ)

Q1: What is the main benefit of the C01 configuration versus the C00 version?

A: The C01 configuration includes a single solid-state alarm relay output, which allows for immediate control actions like machine shutdown or external indicator activation. The C00 version only provides the 4-20 mA signal without any relay functionality.

Q2: How is the alarm limit set on the C01 relay?

A: The alarm setpoint is configured via internal dip switches or jumpers within the TM301 housing, allowing precise adjustment of the vibration level that will trigger the relay action.

Q3: Can the 4-20 mA output be scaled for different vibration ranges?

A: Yes, the 4-20 mA output can be scaled to represent a specific vibration range (e.g., 0 to 10 mils peak-to-peak). This scaling ensures the output signal matches the measurement units used by the plant’s PLC/DCS.

Q4: Is a separate power supply required for the proximity probe?

A: No, the TM301 integrates the necessary driver and signal conditioning circuitry for the proximity probe. It provides the required power and linearization directly, simplifying installation and wiring.
