Description

330750-60-05: High Temperature Velomitor (HTV) system, configured with a 6.0 m integral hardline cable (Option 60) and CSA, ATEX, and IECEx hazardous area approvals (Option 05). This transducer system is engineered for industrial environments where machinery surface temperatures reach up to 400 degC (752 degF). The 330750 system features an integrated design that separates the sensing element from the signal conditioning electronics. The sensing head and hardline cable are constructed to withstand extreme heat, while the electronics are housed remotely in a cooler location, protected from temperatures exceeding 121 degC (250 degF). This configuration eliminates intermediate connectors near the sensor, which are common failure points in high-temperature applications. It delivers reliable vibration performance comparable to standard Velomitor sensors, essential for monitoring shaft and casing vibration in steam turbines and other high-temperature rotating equipment.

Features

  • Option 60: 6 meters of integral hardline cable for flexible positioning of signal conditioning electronics
  • Option 05: Multiple hazardous area certifications including CSA, ATEX, and IECEx
  • Designed for high-temperature machinery environments up to 400 degC (752 degF)
  • Integrated hardline cable eliminates connectors in the high-heat zone
  • Hermetically sealed sensing head for 100% humidity environments
  • Remote signal conditioning electronics withstand ambient temperatures up to 121 degC (250 degF)

Applications

  • High-temperature casing vibration monitoring
  • Steam turbine monitoring
  • Gas turbine auxiliary equipment
  • Rotating machinery in hazardous, high-temperature areas

Installation Guidelines

Install the sensing head directly on the machine casing or bearing housing using the integrated hardline cable. Ensure the signal conditioning electronics housing is mounted in a protected enclosure in an area with ambient temperatures not exceeding 121 degC. Route cabling through conduit to protect against environmental damage. For installations in hazardous areas, strictly adhere to the control drawings and entity parameters provided in the documentation. Use recommended double-shielded cable for the connection between the electronics housing and the monitoring system to minimize electromagnetic interference.

What is the maximum operating temperature for the 330750-60-05 sensor head?
The sensor head and integral hardline cable are designed to operate in environments up to 400 degC (752 degF).

Why does this system separate the electronics from the sensor?
Separating the sensing element from the signal conditioning electronics allows the sensor to survive in extreme heat (up to 400 degC) while the electronics are housed in a cooler, protected location (up to 121 degC).

Does the 330750-60-05 include hazardous area approvals?
Yes, the 05 approval option indicates that this unit meets CSA, ATEX, and IECEx hazardous area requirements.

What does the 60 suffix represent in the orderable part number?
The 60 segment specifies a 6.0 meter cable length for the integral hardline cable.
