Bently Nevada 330101-00-20-05-02-05 Proximity Probes

Bently Nevada's 330101-00-20-05-02-05 is a 3300 XL series 8mm eddy current proximity probe. The following is a detailed description of the model analysis, technical characteristics, application scenarios, etc.:

Product technical features

1. Measurement principle and performance

Based on the eddy current effect, the non-contact measurement probe and the metal measured surface gap converts the displacement signal into a voltage signal (typical linear range: 0-2mm, output voltage -20V to -4V DC), which is suitable for high-precision vibration and displacement monitoring.

Linearity error ≤1%, temperature drift ≤0.05%/℃, ensuring measurement stability under complex working conditions.

2. Physical and environmental characteristics

Probe material: The tip is polyphenylene sulfide (PPS), high temperature resistant (long-term working temperature -30℃~+177℃), corrosion resistant; the shell is AISI 304 stainless steel, protection level IP65, can resist oil, water vapor and mechanical shock.

Cable characteristics: total length 0.5 meters, outer layer is wear-resistant PVC or Teflon material, internal coaxial shielding structure, strong anti-electromagnetic interference ability, low signal transmission attenuation.

3. Installation and compatibility

The shell length is 2.0 inches, suitable for scenes with compact installation space (such as bearing seats, near shaft systems), and needs to be used with 3300 series preamplifiers (such as 330180-90-00) to form a complete monitoring link of "probe-extension cable-preamplifier".

Application scenarios

Industrial rotating machinery monitoring: commonly used in steam turbines, compressors, fans, pumps and other equipment in the fields of petroleum refining, power generation, metallurgical rolling mills, aerospace, etc., monitoring the following parameters:

Shaft vibration (radial vibration amplitude, frequency);

Axial displacement (shaft system movement);

Eccentricity (rotor eccentricity);

Key phase (speed synchronization signal).

Adaptation for special scenarios: Since the E position "05" may involve special certification, the probe can be used in situations that require explosion-proof (such as ATEX, IECEx) or high-temperature environments (the specific certification type must be confirmed in conjunction with the manufacturer's documentation).
