Quick Detail

Description

The 330500-01-00 Velomitor Piezo-Velocity Sensor is a state-of-the-art, industrial-grade vibration monitoring transducer engineered for unparalleled reliability in measuring casing vibration on critical rotating machinery. This premier Velomitor Piezo-velocity Sensor leverages advanced piezoelectric technology to deliver a direct and precise measurement of vibration velocity, providing a superior alternative to traditional moving-coil sensors. A key differentiator of the 330500-01-00 model is its robust construction featuring a 1/4-28 UNF-2B tapped hole for secure mounting and a generous 5.0 meters (16.4 feet) total cable length terminated with a top-mount 2-pin MIL-C-5015 connector, ensuring easy integration into existing monitoring systems.

The core competitive advantage of this velocity sensor lies in its solid-state design, which completely eliminates internal moving parts. This fundamental architecture eradicates mechanical wear, susceptibility to sticking, and performance degradation in high-vibration environments, guaranteeing an extended service life and reduced maintenance costs. Within its compact, stainless steel case, the 330500-01-00 integrates sophisticated signal conditioning electronics. This internal circuitry performs the critical integration of the piezoelectric element's acceleration signal into a stable velocity output directly at the source. The result is a robust, low-impedance voltage output standardized at 3.94 mV/mm/s (100 mV/in/s), which is highly resistant to electromagnetic interference (EMI) and signal loss over long cable runs, even in electrically noisy industrial settings.

Applications

This sensor is ideally deployed for continuous online monitoring of casing vibration on a wide array of rotating machinery such as pumps, fans, blowers, and motors. Its standardized 100 mV/in/s output provides a clear velocity signal that is directly correlated to overall machine health, enabling the effective detection of common faults like imbalance, misalignment, and bearing issues, which facilitates predictive maintenance and helps prevent catastrophic failures.

With its CSA/NRTL/C approval for Class I, Div 2 hazardous areas and a rugged stainless steel construction, the sensor is perfectly suited for installation in demanding environments like refineries, chemical plants, and offshore platforms. The combination of a 5.0-meter cable, a top-mount MIL-C-5015 connector, and a 1/4-28 UNF mounting thread allows for flexible and robust installation directly on bearing housings, even in remote or hard-to-access locations within these facilities.

The sensor's internal integration electronics provide a strong, low-impedance output (less than 2300 Ω), making it exceptionally reliable for applications requiring long cable runs from the machine to the control room. This design ensures signal integrity is maintained over distance without degradation, which is critical for centralized monitoring systems in large plants where accurate vibration data is essential for protecting balance-of-plant assets and ensuring operational safety.

Specifications

Competitive Advantage

1.Solid-State, Zero-Maintenance Design

Unlike conventional moving-coil velocity sensors, the 330500-01-00 contains no internal moving parts such as coils or springs. This pure piezoelectric, solid-state construction eliminates mechanical wear, prevents coil "rub" or sticking, and ensures consistent performance and a dramatically longer service life, especially in environments with high-frequency or high-amplitude vibration that would rapidly degrade electro-mechanical sensors.

2.Integrated Electronics for Superior Signal Fidelity

The sensor features built-in microelectronics that convert the raw piezoelectric acceleration signal into a velocity signal directly within the hermetically sealed case. This integration at the source results in a low-impedance voltage output, which is inherently robust against electromagnetic interference (EMI) and signal loss caused by cable capacitance. This guarantees the accuracy of its 3.94 mV/mm/s sensitivity over its full 5.0-meter cable and in electrically noisy industrial environments.

3.Ruggedized Construction with Hazardous Area Certification

Engineered with a 365L stainless steel case, a military-spec (MIL-C-5015) connector, and an extended operating temperature range (-45°C to +122°C), the sensor is built for physical durability in harsh conditions. Furthermore, its CSA/NRTL/C certification for Class I, Div 2, Groups A-D allows for immediate deployment in a wide range of hazardous locations, reducing installation complexity and providing a certified, off-the-shelf solution for global safety compliance.
