Description

The 330500-04-00 is a high-precision Velomitor Piezo-velocity sensor configured with a 1/4-20 UNC mounting thread adapter (Option 04) and no agency approval (Option 00). This sensor is engineered to measure absolute bearing housing, casing, and structural vibration, providing reliable monitoring data for rotating machinery. As a specialized piezoelectric accelerometer with integrated solid-state electronics, the unit contains no moving parts, preventing mechanical degradation and ensuring a long service life in diverse industrial environments. The 330500 series is suitable for vertical, horizontal, or angled mounting orientations. For optimal signal integrity, it is recommended to install the sensor directly on the machine casing or bearing housing; improper installation can potentially dampen the frequency response or introduce false signals. This configuration, featuring the 1/4-20 UNC adapter, is typically used in applications where specific fastener compatibility is required for secure mechanical attachment.

Features

  • Option 04: Includes 1/4-20 UNC mounting thread adapter for specific installation requirements.
  • Option 00: Standard configuration without hazardous area agency approvals.
  • Solid-state design with no moving parts, eliminating mechanical wear and degradation.
  • 316L stainless steel, hermetically sealed case for durability in industrial settings.
  • Broad frequency response range of 4.5 Hz to 5 kHz (±3.0 dB).
  • Case-isolated grounding to prevent ground loop interference.
  • Standard 2-pin MIL-C-5015 hermetically sealed connector.

Applications

The Velomitor Piezo-velocity sensor is used extensively in heavy industry for casing vibration monitoring, including:
  • Power generation equipment monitoring
  • Oil and gas turbomachinery protection
  • Petrochemical and industrial pump monitoring
  • Rotating machinery balance and alignment verification
