Description

The 330500-01-01 is a Velomitor Piezo-velocity Sensor designed for measuring absolute casing or structural vibration on rotating machinery. This specific configuration features a 1/2-20 UNF mounting thread (Option 01) and CSA/US/C agency approvals (Option 01). Built as a specialized piezoelectric accelerometer with integrated electronics, the 330500 provides a reliable, solid-state solution for machinery protection. Unlike traditional velocity transducers with moving parts that degrade over time, the 330500 sensor is entirely solid-state. It features a robust 316L stainless steel, hermetically sealed housing, allowing for vertical, horizontal, or any other orientation without affecting performance. The unit is used to monitor machine malfunctions such as unbalance and misalignment by detecting changes in casing vibration, making it an essential component in critical machinery monitoring chains.

Features

1/2-20 UNF mounting thread (Option 01) for standard stud installation
CSA/US/C agency approval (Option 01) for hazardous area compliance
Solid-state design with no moving parts to ensure longevity and minimize mechanical wear
316L stainless steel, hermetically sealed housing for durability in harsh industrial environments
Sensitivity of 100 mV/in/s (3.94 mV/mm/s) for accurate vibration measurement
2-pin Mil-C-5015 connector for reliable signal transmission
Suitable for horizontal, vertical, or angled orientation

Applications

Power generation machinery
Hydroelectric turbines
Petrochemical processing equipment
General rotating machinery protection (fans, pumps, motors)
Bearing housing and structural vibration monitoring

Installation Guidelines

Ensure the sensor is installed on a flat, clean surface on the bearing housing or machine casing for optimal frequency response.
Use the specified 1/2-20 UNF mounting adapter (Option 01) and observe the maximum mounting torque of 32-46 kg cm (24-40 in-lb) to prevent damage.
Avoid over-tightening or using improper adapters, which can lead to false signals or degraded amplitude response.
If integrating the output to measure displacement, be aware that electrical noise can be amplified; maintain proper cabling and shielding practices.

What does the 01-01 suffix mean for the 330500 Velomitor?

The 01-01 suffix denotes the specific configuration: 01 for the 1/2-20 UNF mounting thread and 01 for CSA/US/C agency approvals.

Can the 330500 sensor be mounted in any orientation?

Yes, because the 330500 incorporates solid-state electronics and has no moving parts, it can be mounted vertically, horizontally, or at any other angle.

Is the 330500 sensor housing isolated from the ground?

Yes, the 330500 features a case-isolated design.

What is the maximum shock survivability of the 330500?

The sensor is rated for a shock survivability of 5,000 g peak maximum.
