Bently Nevada 330400-02-05 Velomitor Piezoelectric Velocity Sensor

The Bently Nevada 330400-02-05 provides professional vibration monitoring for rotating industrial machinery. This solid-state piezoelectric velocity sensor offers a wide frequency range, stainless steel durability, and seamless integration with 3500 series racks to prevent costly equipment downtime.

The Bently Nevada 330400-02-05 functions as a high-precision piezoelectric velocity transducer designed to monitor the casing vibration of rotating machinery. This sensor measures absolute vibration velocity directly, providing critical data for the protection of pumps, motors, and fans. Because the unit integrates the necessary electronics within its stainless steel housing, it outputs a standard 4-20 mA or raw signal that interfaces seamlessly with Bently Nevada 3500 monitoring systems.

By utilizing a solid-state design with no moving parts, the 330400-02-05 eliminates the mechanical wear typically associated with moving-coil velocity transducers. This sensor executes accurate measurements across a broad frequency range, ensuring it detects early-stage bearing failures and rotor imbalances effectively. Furthermore, the hermetically sealed construction protects internal components from harsh industrial environments, including exposure to moisture, dust, and corrosive chemicals.

Furthermore, the 330400-02-05 simplifies installation through its standardized mounting threads and flexible connector options. It manages high-temperature operations reliably, allowing for continuous monitoring in demanding applications such as cooling towers or gas turbines. Consequently, this Velomitor sensor delivers superior long-term stability and precise vibration data, which enables maintenance teams to implement proactive condition-based monitoring strategies.
