Description

The 190501-09-99-05 Velomitor CT Velocity Transducer is a specialized piezoelectric velocity sensor engineered for low-frequency casing vibration measurements. This configuration features a 3/8-in 24 to 1/4-in NPT plate stud (Option 09) and is supplied with an integrated 32-foot cable (Option 99). This transducer is specifically optimized for air-cooled heat exchangers and cooling tower fan assemblies that typically operate at or above 90 rpm (100 to 300 rpm typical). Designed as a low-frequency variant of the standard Velomitor Piezo-velocity sensor, this unit provides accurate vibration amplitude data for machine protection applications where monitoring at lower frequency ranges is critical. The sensor measures rotor vibration transmitted to the machine casing and is compatible with standard Bently Nevada monitoring systems. Proper installation on the bearing housing or machine casing is required to maintain measurement integrity and frequency response.

Installation Guidelines

Install the transducer directly on the machine casing or bearing housing; improper mounting can lead to signal degradation or false readings.
Ensure the mounting surface is clean and prepared for the 3/8-in 24 thread or adapter interface.
Use the supplied 32-foot integrated cable for signal transmission; ensure cable routing avoids high-EMI zones where possible.
Maintain the 4.5 N-m mounting torque to ensure stable frequency response and transducer performance.
Refer to the Velomitor CT Piezo-Velocity Transducer User Guide (document 125389) for complete wiring and configuration details.
