PROVIBTECH TM521-A02-B00-C02-D00-E01-G00-10-M1 Electrical Eddy Current Shaft Displacement Monitoring Module

I. Product Positioning
Single-channel shaft vibration transducer protection monitoring instrument (electro-vortex shaft displacement monitoring module)
Designed specifically for radial vibration / shaft displacement monitoring of rotating units such as steam turbines, fans, compressors, pumps, etc.; used in conjunction with the Plaris TM0180 series electro-vortex probes + preamplifier to collect shaft clearance displacement signals, convert them into standard analog quantities + relay alarm and interlock outputs. Widely used in power plants, petrochemical DCS/TSI systems.

TM201 Series Main Body: Single-channel Axial Displacement Vibration Monitor Table
Grade Code Details of meaning
A Grade (Measurement Range) A00 Standard range: 0 – 200 μm (peak-to-peak pp)
Suitable for conventional steam turbines and fan shaft vibration monitoring (default main range)
B Grade (Power Supply) B00 DC power supply: DC 24V (±10%) Industrial control cabinet standard power supply
C Grade (Alarm Contact) C00 Internal epoxy resin sealed relay (dual channel: warning ALERT + danger DANGER two sets of passive contacts, configurable for interlock shutdown); C01 = No alarm relay
D Grade (Analog Transmitter Output) D00 Standard industrial output: 4 – 20mA DC (corresponding to 0 – full range displacement, connected to DCS for collection); D01 = 1 – 5V voltage output
E Grade (Buffer Signal Output) E00 Brings BNC buffer for raw signal output
Can be externally connected to oscilloscopes and acquisition instruments for waveform fault analysis; E01 = Cancel buffer output
G Grade (Installation Method) G00 Standard 35mm DIN rail snap-in installation (common in control cabinets); G01 = Bottom plate screw fixed installation
✅ Summary of complete configuration of the entire machine:
0 – 200 μm shaft displacement range, 24VDC power supply, dual-channel alarm relay, 4 – 20mA transducer, BNC buffer signal, DIN rail installation (factory standard model)
