Product Description

Description

Engineered for continuous vibration monitoring in extreme thermal environments, the Bently Nevada 330750-40-05 functions as a specialized High Temperature Velomitor System (HTVS). This system is designed to measure casing velocity vibration on machinery where operating temperatures exceed the limits of standard velocity transducers. By isolating the high-temperature sensing element from the signal-conditioning electronics via an armored interconnect cable, the system ensures stable and reliable signal processing in harsh machinery conditions.

The 330750-40-05 system contains a high-temperature accelerometer, an interconnecting cable, and a charge amplifier that converts charge to a low-impedance voltage output. This structure allows the system to be deployed effectively on gas turbines, steam turbines, and other high-temperature rotating machinery where casing expansion and thermal stress are prevalent.

Features

  • Separated-component architecture keeps sensitive electronics isolated from high-heat zones.
  • Stainless steel armored cable provides robust physical protection in industrial environments.
  • Provides continuous casing vibration data compatible with Bently Nevada 3500 monitoring systems.
  • Designed for rugged industrial applications requiring stability over broad temperature gradients.

Applications

  • Gas turbine casings and exhaust ducts
  • Steam turbine housings
  • High-temperature piping systems and steam valves
  • Hot gas expanders and industrial exhaust fans

Technical Specifications

Manufacturer Bently Nevada
Part Number 330750-40-05
Product Type High Temperature Velomitor System
Cable Length Option (-40) 4.0 meters (13 feet)
Cable Armor Integral stainless steel armor
Approvals Option (-05) Multiple Approvals (CSA, ATEX, and IECEx)
Maximum Sensor Operating Temperature 400 degC
Charge Amplifier Operating Temperature -40 degC to 121 degC

Installation Guidelines

For optimal performance and structural longevity, adhere to the following installation protocols:

  • Sensor Mounting: Ensure the sensor is securely mounted to a flat, clean surface using the specified mounting stud torque to prevent signal attenuation or false resonance.
  • Cable Routing: Route the armored cable away from high-voltage lines and sharp physical edges. Secure the cable with appropriate clamps to minimize motion-induced noise.
  • Amplifier Placement: Mount the charge amplifier in a lower-temperature environment (not exceeding 121 degC) that is clean, dry, and protected from direct thermal radiation.
  • Grounding: Ensure proper shield grounding to prevent ground loops and electromagnetic interference (EMI) from distorting the velocity signal.

Compliance and Certifications

  • CSA: Hazardous area certified for North American industrial standards.
  • ATEX: Certified for explosive atmospheres within European markets.
  • IECEx: Certified for global hazardous area compatibility.
