Bently Nevada 172109-01 Product Details
(High-performance vibration/temperature combination monitoring sensor for precise condition monitoring of rotating machinery)
I.Product Overview
Model:172109-01
Brand:Bently Nevada(a subsidiary of Baker Hughes,a leader in industrial condition monitoring)
Type:Vibration and temperature combination sensor(integrates accelerometer and temperature sensor,enabling dual-parameter monitoring with a single probe)
Core Positioning:
Designed for simultaneous monitoring of vibration(acceleration/velocity/displacement)and temperature for rotating machinery such as turbines,generators,compressors,fans,and pumps.
Suitable for industrial environments subject to high temperatures,high vibration,and strong electromagnetic interference(such as those in the power,oil and gas,chemical,and metallurgical industries).
Compatible with the Bently Nevada 3300/3500/4000 series monitoring systems and System 1 software,supporting predictive maintenance and fault diagnosis.II.System Composition and Core Components
The 172109-01 is typically an integrated sensor,integrating the following functional modules(specific configuration is subject to ordering):
1.Vibration Monitoring Module(Accelerometer)
Model Example:3300 XL 8mm or 3300 XL 13mm Accelerometer(selectable range).
Function:
Measures vibration acceleration(peak,RMS)of the rotor or bearing housing and converts it into velocity or displacement signals.
Supports spectrum analysis to detect typical mechanical issues such as imbalance,misalignment,and bearing failures.
Key Features:
Wide Frequency Response:0.5Hz to 10kHz(acceleration),covering low-frequency vibrations(such as imbalance)to high-frequency vibrations(such as bearing failures).
High Sensitivity:100mV/g(typical),resolution<0.001g.
Shock Resistance:Withstands 500g peak shock,suitable for harsh operating conditions.High-Temperature Resistance:The standard model supports temperatures from-40°C to+120°C,while the high-temperature model(HT)extends to-40°C to+175°C.
2.Temperature Monitoring Module(PT100/PT1000 RTD)
Function:
Real-time monitoring of bearing,gearbox,or motor winding temperatures to prevent equipment damage caused by overheating.
Supports temperature threshold alarms and integrated analysis with vibration data(for example,a sudden increase in vibration accompanied by a temperature rise may indicate a friction fault).
Key Features:
High Accuracy:±0.1°C(0°C to 100°C),±0.3°C(-50°C to 200°C).
Fast Response:Time constant<3 seconds(in air),reflecting temperature changes in real time.
Corrosion Resistance:The probe housing is made of 316L stainless steel,suitable for chemically corrosive environments.
3.Integrated Probe Design
Structure:
The vibration sensor and temperature sensor are integrated into a single probe,reducing installation space and wiring complexity.The probe head is made of titanium alloy or Inconel 600 alloy(high-temperature and corrosion-resistant).
