2、 Core technical parameters
Measurement principle: Non contact measurement using eddy current is adopted, and the distance change between the detection probe and the metal target surface is converted into electrical signals to achieve monitoring of parameters such as vibration and position
Compatible system: It needs to be paired with 3300 NSv extension cable and 3300 XL NSv preamplifier to form a sensor system, jointly completing signal acquisition and conversion
Measurement range: The linear measurement range is 1.5mm (60mil), suitable for small target monitoring, such as radial vibration of shafts with a diameter less than 51mm and axial position measurement of planes with an area less than 15mm
Sensitivity: The system sensitivity is 7.87V/mm (200mV/mil), and the measurement accuracy can reach ± 6.5% in environments ranging from 0 ℃ to 45 ℃.
Frequency response: 0.5Hz to 100kHz, capable of accurately capturing vibration signals of different frequencies.
Temperature characteristics: Operating temperature range -35 ℃ to+85 ℃, storage temperature -51 ℃ to+100 ℃, able to adapt to temperature fluctuations in harsh industrial environments.
Cable parameters: The typical value of standard cable capacitance is 69.9pF/m, the impedance of the shielding layer is 0.066 Ω/m, the signal transmission loss is low, and the anti-interference ability is strong.
3、 Physical and installation parameters
Probe material: The probe housing is made of 304 stainless steel, which is wear-resistant and corrosion-resistant; The probe tip is made of polyphenylene sulfide (PPS), which has excellent insulation and high temperature resistance
Installation method: Using 1/4-28 UNF thread installation, it can be directly fixed to the mechanical preset installation hole without the need for additional fixing structures; Supports panel installation or DIN rail installation (requires matching preamplifier installation components).
Weight: Approximately 14-150g (depending on installation accessories), lightweight and has little impact on the load of the installation structure.
4、 Environmental and compliance parameters
Humidity adaptation: In the protected state of the connector, it can adapt to a 100% condensing environment (non immersed) and a relative humidity of 5% -95% (non condensing)
Anti interference: It has good radio frequency interference (RFI)/electromagnetic interference (EMI) immunity and can meet CE certification requirements without special installation, avoiding high-frequency signal interference and measurement accuracy.
Compliance standards: Complies with CE, UL standards, and API 670 specifications for rotating machinery monitoring systems, with the country of origin being the United States
