330500-04-04 Velomitor Piezo-velocity Sensor is a specialized piezoelectric accelerometer designed for measuring absolute casing, bearing housing, and structural vibration. This configuration features a 1/4-20 UNC mounting thread adapter (Option 04) and is rated for multiple hazardous area approvals (Option 04: CSA, ATEX), allowing for versatile installation in demanding industrial environments.
The 330500 incorporates solid-state piezoelectric technology with embedded integrated electronics. With no moving parts, the sensor is resistant to mechanical wear and can be mounted in any orientation—vertical, horizontal, or angled. It is a critical component for machinery protection systems where continuous transmission of casing vibration is required to monitor for malfunctions such as unbalance or misalignment.

Ensure the sensor is installed directly on the bearing housing or machine casing. Improper installation, such as loose mounting or poor surface contact, may decrease amplitude and frequency response or generate false signals. Use the provided 1/4-20 UNC mounting adapter and adhere to the specified mounting torque of 32-46 kg cm. Always consult the 330500 user manual for hazardous area installation instructions corresponding to the selected approval rating.
