Analysis of Parameters and Functional Effects of Bentley 330851-03-000-010-10-00-00-05

1、 Model code analysis

The model coding of Bentley sensors usually follows the logic of "series type size characteristics interface options". Taking 330851-03-000-010-10-00-00-05 as an example:

330851: Basic model, indicating belonging to the 3300 series eddy current displacement sensor, used for non-contact measurement of relative displacement of metal objects.

03: It may represent the type or installation method of the probe (such as standard probe, high-temperature resistant probe, etc.), which needs to be confirmed in conjunction with the specific product manual.

000: Usually represents the measurement range (such as 0-2mm or 0-5mm), but the unit needs to be confirmed with reference to the document.

010: May involve output sensitivity (such as 10mV/μ m) or frequency response range (such as 0-10kHz).

10: Possible cable length (e.g. 10 meters) or electrical interface type (e.g. M12 connector).

00: It is usually a spare field used to distinguish between different versions or special configurations.

05: May indicate probe diameter (e.g. 5mm) or protection level (e.g. IP65).

Note: Due to Bentley's incomplete disclosure of coding rules, some parameters need to be confirmed through product manuals or technical support.

2、 Core parameters (based on speculation of similar products)

parameter categoryTypical value (speculative)explanation

measurement range0-2mm or 0-5mmSuitable for scenarios such as axial displacement and differential expansion, the specific scope needs to be confirmed.

Output sensitivity8mV/μm 或 10 mV/μmLinear output, easy to be compatible with monitoring systems (such as 3500/20 modules).

frequency response0-10kHzCapable of capturing high-speed vibration signals, suitable for rotating machinery such as steam turbines and compressors.

Probe diameter5mm or 8mmSmall diameter probes are suitable for installation in narrow spaces, while large diameter probes improve signal-to-noise ratio.

cable length5m or 10mExtension cables (such as 330130 series) can extend the transmission distance and need to be matched with a preamplifier.

environmental adaptability-40 ℃~+120 ℃ (high temperature resistant models can reach+200 ℃)Suitable for harsh environments such as chemical and electrical engineering, some models have explosion-proof certification.

3、 Functional function

Non contact displacement measurement

By detecting the gap changes between the metal target surface and the probe end through eddy current effect, real-time monitoring of parameters such as axial displacement, radial vibration, and expansion difference can be achieved.

Typical applications: Monitoring of clearance between turbine rotor and stator, and detection of axial thrust bearing wear in compressors.

Key mechanical protection

In conjunction with the 3500/20 displacement monitoring module, set alarm thresholds (such as 50 μ m alarm and 75 μ m shutdown) to prevent friction between the rotor and stator.

Support overspeed protection (via 3500/32 speed module) and start stop process analysis.

Vibration analysis and fault diagnosis

Provide high-precision displacement signals, combined with the 3500/42 vibration monitoring module, to analyze vibration amplitude, phase, and spectrum, diagnose faults such as imbalance, misalignment, and looseness.

Keyphasor measurement (via 3500/15 module) provides a phase reference for vibration analysis to determine the fault location.

Compatibility and Scalability

Support 3300 series preamplifiers (such as 330180-50-00) and extension cables to form a complete signal conditioning link.

It can be integrated into the 3500 framework system and work together with relay modules (3500/25), communication gateways (3500/50), etc. to achieve automation control and remote diagnosis.
