The Axial Sensor Unit ASSY 3003 is an OEM replacement axial magnetic‑float sensor assembly designed for use with Shimadzu TMP molecular pumps. It is an authentic repair component intended to restore accurate axial position sensing and reliable operation in compatible TMP units.
Key identification:
- Product name: Axial Sensor Unit, ASSY 3003
- Function: Axial magnetic/float position sensing for rotor assembly
- Intended use: Original parts repair for TMP series molecular pumps
Compatibility:
- Primary fit: TMP‑2003 and TMP‑3603 series
- Catalog references also show use in TMP‑3003 through TMP‑3603 repair kits; confirm the exact model and serial before ordering
Features and benefits:
- OEM quality — manufactured to match Shimadzu factory tolerances for fit and function
- Axial sensing optimized for stable rotor levitation detection and monitoring
- Compact assembly simplifies replacement and reduces downtime compared with in‑field repairs
- Supports reliable pump control and safety interlocks that depend on accurate axial position feedback
Typical applications:
- Service and overhaul of TMP‑2003 / TMP‑3003 / TMP‑3603 family molecular pumps
- Preventive maintenance spare to keep critical vacuum systems online
- Repair shops and service centers stocking authentic replacement parts
Installation notes (general guidance):
- Power down the pump and isolate it from the vacuum and power systems before beginning.
- Refer to the pump service manual for rotor handling and clean‑room procedures.
- Remove the old axial sensor assembly following the manufacturer steps; carefully align the ASSY 3003 during installation.
- Verify sensor alignment and clearances; perform the pump’s recommended calibration and functional checks after reassembly.
Precautions:
- Only trained personnel should perform installation and calibration.
- Avoid magnetic contamination and mechanical shock to the sensor element.
- Always verify model and serial compatibility to ensure correct fit.
