Bently Nevada 190501-12-00-CN Velomitor CT Velocity Transducer

Description

Monitoring machinery vibration in harsh industrial environments requires highly stable, specialized sensors. The 190501-12-00-CN is a heavy-duty velocity transducer engineered specifically for low-speed machinery monitoring, such as cooling tower fans and slow-speed pumps. This solid-state design measures absolute vibration velocity, providing critical mechanical health data to assist maintenance teams in detecting unbalance, misalignment, or structural looseness before failures occur.

The transducer integrates onboard electronics to convert the sensor's internal piezo-element charge into a low-impedance voltage signal. Protected by a rugged, hermetically sealed 316L stainless steel housing and featuring a top-exit MIL-C-5015 2-pin connector, the device maintains sealing integrity in wet, corrosive, or dusty environments. This specific configuration includes the -CN option for localized regional compliance and a plate stud mounting adapter.

Features

• Low-frequency velocity measurement optimized for cooling towers and low-speed machinery.
• Rugged, hermetically sealed 316L stainless steel housing for long-term corrosion resistance.
• Top-connection design utilizing a standard 2-pin MIL-C-5015 interface.
• Solid-state electronics for stable vibration signal transmission with minimal signal drift.
• Plate Stud mounting hardware (3/8-in 24 to M8x1) included for versatile mechanical coupling.

Applications

• Cooling tower fans and drive shafts
• Low-speed industrial pumps and agitators
• Air-cooled condensers (ACC)
• General balance-of-plant machinery monitoring

Installation Guidelines

• Ensure the machinery mounting surface is smooth, clean, and flat to a minimum of 33 mm diameter to guarantee proper mechanical frequency transmission.
• Apply the specified mounting torque of 4.5 N-m (+/- 0.6 N-m) using a calibrated torque wrench. Over-tightening may damage the internal sensing element, while under-tightening can lead to signal attenuation.
• Ensure the supplied Plate Stud (3/8-in 24 to M8x1) is fully engaged and aligned straight.
• Route the connection cable with appropriate strain relief loop to avoid putting mechanical tension on the 2-pin MIL-C-5015 top connector.

Compliance and Certifications

• China localized agency approvals (specified by the -CN suffix).
