Description

The 330500-07-04 is a Velomitor Piezo-velocity Sensor designed for measuring absolute casing, bearing housing, or structural vibration. This configuration features a 3/8-16 UNC mounting thread adapter (Option 07) and does not include specific agency approval certifications (Option 00, base configuration for non-hazardous locations). As a specialized piezoelectric accelerometer, the 330500 integrates solid-state electronics, eliminating moving parts and ensuring resistance to mechanical wear and degradation. It supports flexible installation, allowing for vertical, horizontal, or angled mounting orientations on machine housings.

The sensor provides a continuous, reliable output by measuring velocity, making it effective for identifying common machine malfunctions such as unbalance and misalignment. It is compatible with a wide range of Bently Nevada monitoring systems. Proper installation on the bearing housing or casing is required to maintain the specified frequency and amplitude response; for integration into monitoring chains, this sensor requires compatible interconnection cables.

Features

Option 07 mounting: Includes 3/8-16 UNC mounting thread adapter.
Solid-state design: No moving parts, eliminating mechanical degradation.
Output: 3.94 mV/mm/s (100 mV/in/s) nominal sensitivity.
Housing: 316L stainless steel, hermetically sealed construction.
Mounting: Compatible with vertical, horizontal, and angular orientations.
Connector: Standard 2-pin MIL-C-5015 hermetically sealed stainless steel shell.

Applications

Bearing housing vibration monitoring
Casing vibration measurements
Structural vibration analysis
Rotating machinery protection (unbalance and misalignment detection)
Power generation, petrochemical, and industrial rotating equipment

Installation Guidelines

Ensure the sensor is mounted directly on the bearing housing or machine casing for optimal vibration transmission.
Use the specified mounting torque of 32-46 kg cm (24-40 in-lb) to ensure accurate frequency response.
The sensor case is isolated; ensure proper shield grounding at the monitor end per installation documentation.
Avoid using the 330500 for displacement measurements if electrical noise is a concern, as integration can amplify interference.

FAQ

What does the 07 option code indicate for the 330500 sensor?

The 07 option code specifies that the sensor is supplied with a 3/8-16 UNC mounting thread adapter.

Can the 330500-07-04 be mounted in any orientation?

Yes, the Velomitor sensor utilizes solid-state piezoelectric technology and can be mounted vertically, horizontally, or at any angle.

What is the standard sensitivity of this Velomitor sensor?

The 330500 provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) +/- 5%.

Is this sensor suitable for displacement measurements?

While it measures vibration, it is designed for velocity. Integrating the output for displacement can amplify electrical noise and degrade performance, so it is generally not recommended.
