The TSW 101 M1 is a single-channel vibration transmitter that forms a complete monitoring unit comprising the TSW 101 M1 main module, a WW007 eddy-current probe, and a 10-meter cable.

Designed specifically for measuring the relative shaft vibration of rotating machinery, this product utilizes eddy-current technology to perform non-contact relative vibration (Sppm) measurements on rotating shafts, serving as a critical component in equipment condition monitoring and protection systems.

It is widely used in industries such as power generation, petrochemicals, and metallurgy, and is suitable for the vibration monitoring and protection of turbines, generators, compressors, pumps, and various types of industrial rotating machinery.

1. Status Check: Periodically observe the green "Ready" LED indicator on the device to ensure it remains steadily lit, confirming normal operation.
2. Connection Check: Periodically inspect all cable connectors and terminals to ensure they are secure and free from signs of looseness or corrosion.
3. Cleaning: Keep the device housing clean and prevent the accumulation of dust and oil, especially in humid environments.
4. Environmental Check: Ensure the operating temperature and humidity remain within the specified ranges (-25 to +85 °C).
5. Probe Check: Periodically inspect the surface of the eddy current sensor probe to ensure it is clean and free of metal debris or other deposits.

The TSW 101 M1 is widely used for shaft monitoring in large centrifugal compressor or steam turbine units. It is installed near the bearing housing, with its connected eddy-current sensor probe positioned to face the surface of the rotating shaft.

The transmitter converts the shaft vibration amplitude into a 4-20 mA signal in real time, transmitting it to a central control room (DCS/PLC) or a dedicated machinery protection system.

When vibration levels exceed preset alarm or trip thresholds, the system immediately issues an alarm or initiates a shutdown, effectively preventing major equipment failures caused by issues such as rotor imbalance, misalignment, or bearing wear.

The sensor's sensitivity can be readjusted using the "S" potentiometer on the device to ensure measurement accuracy.

Yes. The 4mA zero point can be fine-tuned using the "Z" potentiometer on the device, with a compensation range of approximately ±0.15mA.

This indicates a device fault. Possible causes include: 1. The distance between the target and the probe exceeds the static measurement range; 2. There is an open circuit or short circuit in the eddy current sensor or its connecting cable.

Standard industrial warranty: 12 months; with proper installation and no overloading, the product has a service life of 5-10 years.
