Product No.: 330505-02 - General Introduction
This product is a specialized cable assembly or connectorized adapter for industrial sensor systems. It belongs to a family of interconnect components designed for precision measurement and signal transmission, most commonly associated with vibration, position, or speed monitoring systems. The "-02" suffix typically denotes a specific variant within that family, such as a particular cable length, connector type, or termination style.
Given the root code "330505", this part is likely not a sensor or monitor itself, but a critical passive component that ensures signal integrity between the transducer and the monitoring electronics. It is engineered for durability, shielding, and precise electrical characteristics in harsh industrial environments.
Detailed Parameters
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Product Type | Interconnection Cable Assembly or Adapter | Likely a pre-assembled, tested unit with connectors pre-installed on both ends. |
| Function | Signal Extension or Interface Conversion | Probable functions: 1. Extension Cable: Extends the reach of a sensor (e.g., proximity probe, accelerometer). 2. Adapter/Converter: Changes connector gender or type (e.g., from a probe's integral cable to a monitor's bulkhead connector). |
| Connector Type (End 1) | Industry-standard, likely a threaded, mil-spec style (e.g., similar to Bendix/LEMO, or Micro-D type). | Common in high-reliability monitoring systems for vibration probes (e.g., 8mm or 11mm eddy current probes). |
| Connector Type (End 2) | Matching threaded connector, or a different type for panel entry (e.g., a bulkhead connector or a terminal block). | The "-02" may specify this exact mating style. |
| Cable Type & Length | Double/Triple-shielded coaxial or triaxial cable. Length: Defined by the "-02" variant. Common standard lengths are 5m, 10m, etc. | Shielding is critical for noise immunity in low-level analog signals. Length is fixed per part number. |
| Cable Jacket | Oil-resistant, flexible PVC or PUR (Polyurethane). | PUR offers better resistance to oils, chemicals, and abrasion. |
| Electrical Characteristics | Impedance: Likely 50 or 75 ohms (coaxial). Capacitance: Specified per meter to ensure system calibration. | These parameters are tightly controlled to maintain the system's overall scale factor (mV/mil or mV/µm). |
| Overall Dimensions | Diameter: ~5-8 mm (cable) Dimensions N/A for assembly as a whole. | The functional size is defined by the coiled or straightened length of the cable. |
| Weight | Approx. 0.5 - 2.0 kg | Highly dependent on cable length and connector types. A 10-meter cable with metal connectors can weigh over 1 kg. |
| Temperature Rating | -40°C to +150°C (for cable jacket and internal insulation). | Suitable for high-temperature environments near turbines and engines. |
| Protection Rating | IP67 at connectors (when mated). | Ensures integrity in wet or dusty conditions. |
| Key Feature | Precision-matched electrical length and impedance. | Ensures that when used with a specific sensor (e.g., an eddy current probe), the total system sensitivity remains within specification, avoiding measurement errors. |
| Color | Typically black or yellow for high visibility and durability. |
Primary Application Scenarios
This component is a critical link in the signal chain for machinery condition monitoring.
Turbomachinery Monitoring System Installation:
Probe to Monitor Connection: Used as the extension cable to connect an eddy current proximity probe (mounted on a bearing housing) to the monitoring system rack (e.g., Bently Nevada 3500 or 3300 system) located in a control panel several meters away.
Retrofit and Sensor Replacement:
Direct Replacement Part: When replacing a failed sensor cable in an existing installation, this specific part number ensures electrical and mechanical compatibility, preserving the original system calibration.
Test Bench and Calibration Setups:
Reference Connection: Used in a laboratory or calibration workshop to connect a reference transducer to a calibration exciter or data acquisition system, providing a known-good signal path.
High-Vibration Environment Routing:
Secure Signal Transmission: Its robust connectors and shielded cable are designed to withstand the high-vibration environment near rotating machinery without signal degradation or connector loosening.
System Expansion:
Adding Monitoring Points: When adding a new vibration or position measurement point to an existing system, this cable assembly is used to run the signal from the new probe location back to the monitor rack.
