Description
The Bently Nevada 330500-03-04 Velomitor® Piezo-Velocity Sensor is a high-performance vibration monitoring device developed for industrial machinery condition monitoring and protection applications. The sensor employs advanced piezoelectric technology combined with integrated electronics to directly generate a velocity output signal proportional to machine vibration levels. This approach eliminates the mechanical limitations associated with traditional moving-coil velocity sensors while providing stable measurement performance over extended operating periods.
The sensor is designed to monitor absolute vibration on bearing housings, machine casings, and structural components. Its wide frequency response enables effective detection of imbalance, misalignment, looseness, bearing defects, and other mechanical conditions that affect rotating equipment performance. The solid-state sensing element delivers high reliability and resistance to mechanical wear, making it suitable for continuous online monitoring systems.

Features:
- Piezoelectric velocity sensing technology
- Direct velocity output
- Wide frequency response range
- Solid-state design with no moving parts
- Hermetically sealed housing
- Suitable for harsh industrial environments
Unlike traditional moving-coil velocity sensors, the Velomitor® incorporates a solid-state piezoelectric design that eliminates mechanical wear components, providing excellent long-term reliability and wide frequency response. The sensor is commonly installed on motors, pumps, fans, compressors, gearboxes, turbines, and auxiliary rotating equipment in industrial facilities.
The 330500-03-04 Bently Nevada Velomitor Piezo-velocity Sensor may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Thread Locking: Apply one drop of Loctite 242 (or equivalent medium-strength threadlocker) to both ends of the adapter stud.
Acoustic Coupling: Smear a thin layer of ultrasonic couplant or light machine oil onto the flat pad to eliminate tiny air gaps.
Initial Fitting: Hand-tighten the 1/4-28 UNF stud into the base of the Velomitor sensor body.
Final Torque: Use a calibrated torque wrench to securely bolt the sensor housing onto the machine casing to exactly 2.7 to 4.5 N⋅m (24 to 40 in⋅lbf).

FAQs
-
What is the maximum cable length I can use?
+You can run cable up to a maximum length of 305 meters (1,000 feet) without significant signal degradation. -
What are the thread sizes (the -03-04 designation)?
+The -03 portion indicates standard mounting hardware, while the -04 specifies the exact thread adaptor (1/4-28 UNF). Alternate versions (like the -02-04) may use an M8 × 1 thread. -
What is the maximum torque allowed during installation?
+The sensor should be fastened to a flat surface with a tightening torque between 32 to 46 kg-cm (24 to 40 in-lb). -
What are the official operational temperature boundaries?
+The sensor is rated to survive and operate in extreme temperatures ranging from -55°C to +121°C (-67°F to +250°F)
