The Bently Nevada 330750-40 vibration sensor system is a high-performance vibration monitoring device specifically designed for high-temperature environments. The following is a detailed introduction to this system:
I. Core Parameters
Model: 330750-40
Brand: Bently Nevada (a brand under Baker Hughes)
Sensor Type: Piezoelectric speed sensor, using piezoelectric ceramic shear mode elements, without moving parts, with high long-term stability.
Inducer Head Temperature Resistance: Capable of withstanding a maximum surface temperature of +400°C (+752°F), breaking through the temperature limitations of traditional sensors due to the shared housing of electronic and sensing components (traditional models have a maximum of only +121°C +250°F).
Electronic Component Operating Temperature Range: -55°C to +121°C (-67°F to +250°F), suitable for extreme environments.
Impact Resistance: Peak impact resistance reaches 24,535 m/s² (2500g), suitable for high-vibration and high-impact scenarios.
Shell Material: 300 series stainless steel, with strong corrosion resistance.
Sealing: The shell and connectors (2-pin Mil-C-5015 type) are all airtight sealed. The relative humidity in non-immersion conditions can reach 100%.
Cable Length and Weight: Multiple length versions are provided, such as the 4-meter version with a typical weight of approximately 794 grams (1.75 pounds), and the other lengths (2 meters, 6 meters, 8 meters) have weights increasing successively.
Technical Features
High Temperature Adaptability: Through the design of separating the sensing head from the signal processing circuit and using a sturdy cable connection, the sensing head can be directly installed on high-temperature surfaces (such as turbines, boilers, high-temperature pipelines, etc.), while the electronic components are kept away from the heat source to ensure signal stability.
Precise Measurement: Based on the piezoelectric effect, mechanical vibrations are directly converted into electrical signals without the need for moving parts, resulting in high measurement accuracy and fast response speed.
Strong Anti-interference Capability: Compliant with multiple international safety standards such as CSA, ATEX, and IECEx, suitable for hazardous areas (such as Class I, Zone 2; Class I, Div 2, Groups A, B, C, D). The European ATEX certification includes II 1 G Ex ia IIC T4 (temperature group T4, applicable environmental temperature -40°C to +100°C) and II 3 G Ex nA IIC T4 (same temperature range).
Industrial Compatibility: Supports PLC programming, provides memory, I/O, and communication functions, and can be seamlessly integrated into existing industrial control systems.
