Vibration TFM677

Description

The TFM677 is a tracking filter module in the Vibro-Meter VM600 series Mechanical Protection System (MPS) produced in Switzerland.

The Vibration TFM677 module works in coordination with other monitoring equipment to track and ensure the status of the operating characteristics of mechanical equipment.

Function

The main functions of the Vibro-Meter TFM677 module include tracking and filtering the input signals, filtering out unwanted signal components caused by electromagnetic interference and radio frequency interference, etc., to ensure the high fidelity and reliability of the monitoring data. All input signals enter the TFM677 through sub-modules such as SIOP270, and then the processed signals will be sent for further analysis and processing.

Technical Characteristics

Diversity and Programmability of Signal Input

It can receive a series of dynamic signal inputs, including acceleration, velocity, displacement (proximity) signals, etc. Moreover, these inputs are fully programmable and can meet the monitoring requirements of different equipment and working conditions.

Multi-parameter Measurement Capability

The on-board multi-channel processing function of the Vibro-Meter TFM668 can measure physical parameters such as relative and absolute vibration, maximum vibration amplitude, eccentricity, thrust position, absolute and differential casing expansion, displacement, and dynamic pressure, which helps to deepen the understanding of the operating state of mechanical equipment.

Compatibility of Speed Input

The speed (tachometer) input can receive signals from different speed sensors, which may be based on proximity probes, magnetic pulse pickups or TTL signals. Moreover, this input supports fractional tachometer ratios, making it applicable to various rotational speed monitoring scenarios.

Digital Processing Functions

The Vibro-Meter TFM677 is equipped with a digital processor, which can perform operations such as digital filtering, integration or differentiation as required, rectification according to root mean square, average value, true peak value or peak-to-peak value, order tracking of amplitude and phase, and sensor-target clearance measurement, etc. Therefore, it can conduct routine analysis and processing on the input signals to extract meaningful information.

Configurable Output

Selection of Configuration Units

The settings of the Vibro-Meter TFM677 can be expressed in metric or imperial units for the convenience of users.

Programmable Alarm Settings

The alarm and danger set points are programmable, and the alarm time delay, hysteresis and latching functions can also be set. In addition, the alarm and danger levels can be adjusted according to the rotational speed or other external information, improving the adaptability and flexibility of the system to various requirements.

Multiple Output Signals

The TFM677 outputs vibration and speed signals as analog output signals at the rear of each rack (the front panel of IOC4T), including voltage (0 to 10V) and current (4 to 20mA) signals, which is very convenient for connection and data transmission with other equipment.
