The Vibro-Meter TQ412 111-412-000-012 serves as a high-performance non-contact displacement transducer. This sensor specifically supports the VM600 series for machinery protection and condition monitoring. Its reverse-mount design facilitates installation through machine housings or brackets.
This transducer utilizes the eddy current principle to track metallic target movements. It measures shaft vibration, axial position, and relative expansion in rotating machinery. The system adheres to API 670 standards to ensure industrial reliability.
Key Functional Features
- Precision measurement range of 2 mm to 4 mm for gap monitoring.
- Reverse-mount configuration allows external adjustment and easy maintenance access.
- Torlon-tipped probe construction protects the internal coil from harsh environments.
- Full temperature compensation ensures signal stability between -40°C and +180°C.
- High-frequency response from DC up to 20 kHz captures rapid transients.
- Seamless integration with IQS900 signal conditioners for SIL 2 applications.
