Core technical features
1. High-frequency precision sensing
CE134 444-134-000-145 adopting ceramic compression sensing core to achieve 5Hz~10kHz ultra-wide frequency response (-3dB@5Hz, ±5% accuracy covering 10-5000Hz)
2. Extreme environment endurance
The sensor head withstands -55~350℃ extreme temperature (A zone), and CE134 444-134-000-145 supports -40~125℃ continuous operation (C zone)
INCONEL® alloy sensor head + 316 stainless steel armored hose, 2000g mechanical shock certification, 100% moisture-proof and salt spray corrosion-proof
3. Intelligent signal transmission
2-wire current modulation output (15-28V DC power supply), **＞100m long-distance lossless transmission**
CE134 444-134-000-145 built-in temperature zoning isolation technology to avoid the risk of electronic component failure in high temperature areas
Revolutionary structural design
1. Trinity sealed fortress
The sensor head, armored hose (135g/m line weight), and electronic module are laser sealed and welded to form an absolutely sealed body, completely blocking lubricating oil, high-pressure steam, coolant and chemical pollutants, and the protection performance exceeds the IP68 standard.
2. Connector-free architecture
The external connector design in the high-temperature zone is cancelled, and the signal is directly connected to the electronic module (temperature zone C) through the overall shielded cable, eliminating the signal attenuation problem caused by interface aging in a 350°C environment.
Core application scenarios
◼ Gas turbine blade flutter monitoring (＞5kHz high-frequency acquisition)
◼ Centrifugal compressor bearing failure warning
◼ Offshore platform turbine generator health diagnosis
