سنسور سرعت پیزو ولومیتور بنتلی نوادا 330500-05-01

Description

330500-05-01: Bently Nevada Velomitor piezo-velocity sensor configured with Option 05 mounting thread adaptor (unavailable for standard 330500, directing NPT installations to model 330525) and Option 01 CSA/US/C hazardous area certification.

This specific configuration incorporates a hermetically-sealed 316L stainless steel case housing embedded solid-state electronics, making it immune to mechanical wear and degradation. Unlike moving-parts velocity transducers, this piezo-velocity sensor can be mounted at any orientation angle. The sensor provides an output sensitivity of 3.94 mV/mm/s (100 mV/in/s) to measure absolute structural, casing, or bearing housing vibration in demanding industrial machinery environments.

Features

• Option 05 mounting thread option indicating specialized configuration or standard adapter substitution.
• Option 01 CSA/US/C hazardous area approval package for Class I, Division 1 (Groups A, B, C, D) locations.
• Solid-state piezoelectric design with no moving parts to prevent mechanical wear and degradation.
• 3.94 mV/mm/s (100 mV/in/s) output sensitivity with plus or minus 5% accuracy.
• Broad frequency response from 4.5 Hz to 5 kHz (plus or minus 3.0 dB) or 6.0 Hz to 2.5 kHz (plus or minus 0.9 dB).
• Case-isolated electrical grounding to prevent noise interference.
• Hermetically-sealed 316L stainless steel case with a 2-pin Mil-C-5015 receptacle connector.
• Operating temperature range of -55 degC to 121 degC.

Applications

• Shaft casing, structural, or bearing housing vibration monitoring.
• Rotating machinery protection (unbalance, misalignment, rotor faults).
• Power generation, oil and gas, petrochemical, and other heavy-industry environments.

Connections and Interfaces

Installation Guidelines

• Mount the sensor on a flat, clean surface of the bearing housing or machine casing to maintain optimal amplitude and frequency response.
• Apply mounting torque within the specified range of 32 to 46 kg-cm (24 to 40 in-lb) maximum. Do not exceed these limits.
• Ensure proper electrical shielding. The sensor case is electrically isolated, requiring proper termination of the cable shield to prevent noise.
• Avoid integrating the sensor output to measure displacement unless electrical noise from interference is actively mitigated.
• Use only compatible twisted, shielded 2-conductor cable assemblies (such as Bently Nevada part number 02173006) for connections.

Compliance and Certifications

• CSA/NRTL/C: Class I, Div 1 Groups A, B, C, D; Class II, Groups E, F, G; Class III (Ex ia IIC T3, AEx ia IIC T3, Temp Code T3 @ -55 degC to 121 degC).
• EMC Directive: 2014/30/EU.
• RoHS Directive: 2011/65/EU.
• FCC: Part 15 Compliant.
• Maritime: ABS Marine Vessels, Offshore Units and Structures, Mobile Offshore Units.
