core advantages
1. Reliable operation in extreme environments
180°C continuous operation + 220°C short-term survival, suitable for gas turbine exhaust section, hydraulic system high temperature area.
IP68 protection + FEP sheath (optional) resists oil, chemical corrosion and high-pressure flushing.
2. Micron-level accuracy guarantee
Temperature compensation algorithm eliminates -30°C~150°C drift (error <5%) to ensure long-term stability.
20 kHz wide frequency response captures high-frequency vibration events (such as early harmonics of bearing failure).
3. Safety and diagnostic integration
When paired with diagnostic IQS900, TQ912 111-912-000-011-A1-B1-E1000-F0-G0-H10 exceeds the limit (<-20.5mA or >-15.5mA) to indicate chain fault (sensor/cable/conditioner) in real time.
SIL 2 "design level" certification, directly used in functional safety systems (such as overspeed protection ODS).
4. Modular and fast upgrade
Fully interchangeable components can directly replace traditional TQ4xx systems (such as IQS900 replacing IQS45x).
TQ912 111-912-000-011-A1-B1-E1000-F0-G0-H10 supports on-site chain length fine-tuning (±0.1m electrical compensation) to optimize system response.
Typical application scenarios
Energy and power: Steam turbine shaft vibration monitoring, gas generator axial displacement protection
Oil and gas chemical industry: Centrifugal compressor bearing vibration analysis, pump seal clearance control
