330101-00-20-20-02-RU Bently Nevada Sensor Probe

Bently Nevada's 330101-00-20-20-02-RU is a 3300 XL series eddy current proximity probe. The following is an explanation of the model, technical characteristics, application scenarios and special markings:

Model Meaning Analysis

330101: Fixed prefix, representing the 3300 XL series 8mm eddy current probe body.

Position A "00": The unthreaded length is 0.0 inches (the probe housing has no additional threaded section, which is a standard design).

Position B "20": The total length of the probe housing is 2.0 inches (about 50.8mm).

Position C "20": The total length of the probe (including cable) is 2.0 meters (6.56 feet).

Position D "02": The connector type is a micro coaxial ClickLoc connector, with standard cable configuration.

E position "RU": special suffix identification (non-traditional digital coding), usually related to Russian market certification or customized configuration (such as compliance with Russian explosion-proof standards, climate adaptability certification, etc.).

Product technical features

1. Core measurement performance

Based on the eddy current effect, non-contact measurement of metal surface displacement, linear measurement range 0-2mm, output voltage -20V to -4V DC (typical value), linearity error ≤1%, suitable for high-precision vibration and shaft displacement monitoring.

Strong temperature stability, the probe body operating temperature range is -30℃~+177℃, the cable temperature resistance is -55℃~+125℃, suitable for harsh industrial environments.

2. Structure and material

Probe housing: AISI 304 stainless steel, protection level IP65, corrosion-resistant and wear-resistant; the tip is polyphenylene sulfide (PPS), with good insulation and high temperature resistance.

Cable characteristics: total length 2.0 meters, outer layer is wear-resistant PVC or Teflon material, internal coaxial shielding design, anti-electromagnetic interference, low signal transmission attenuation rate (capacitance per meter ≤50pF, resistance ≤0.1Ω).

Connector: Micro ClickLoc connector, easy to plug and unplug, anti-vibration loosening, connected to impedance matching preamplifier (such as 330180 series).

3. The special meaning of the "RU" suffix

It may involve Russian national standard certification (such as GOST certification), or cable materials optimized for Russian climate zones (such as severe cold environments) (enhanced low temperature resistance and flexibility).

It may also be related to explosion-proof certification (such as compliance with Russian explosion-proof standard RTN 0322-2013), suitable for hazardous areas such as oil and gas, chemical industry, etc.

Application scenarios

Industrial rotating machinery monitoring: Applicable to shaft system status monitoring of equipment such as steam turbines, compressors, fans, pumps, etc. Specific parameters include:

Radial vibration (amplitude, frequency analysis);

Axial displacement (shaft movement control);

Rotor eccentricity, key phase (speed synchronization).

Special environment adaptation:

Industrial projects in Russia and CIS countries (because the "RU" logo may be associated with local certification);

Scenarios that require low temperature resistance (such as below - 40℃) or compliance with local electromagnetic compatibility standards.
