190501-09-00-CN | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the 190501-09-00-CN

When unplanned downtime strikes, the 190501-09-00-CN from Bently Nevada provides the critical vibration data you need to act fast. This Velomitor CT Velocity Transducer is engineered for continuous monitoring of rotating equipment, helping you avoid costly failures and extend machinery life.

With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, the 190501-09-00-CN delivers accurate velocity measurements across a broad frequency range. Its robust design and country-specific approval option (CN) make it a reliable choice for industrial applications worldwide.

Key Features and Technical Specifications

The 190501-09-00-CN stands out with its exceptional performance and durability. Here are the core specs you can rely on:

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%
• Frequency Response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB; 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk, maximum
• Case Material: 316L stainless steel
• Mounting Hardware: Plate Stud 3/8-in 24 to 1/4-in NPT
• Connection: MIL-C-5015 connection interface
• Weight: 0.297 kg (10.5 oz) typical

One distinctive spec is the mounted resonant frequency of 9 kHz minimum (stud mounted). This ensures stable readings even in high-frequency environments, reducing false alarms and maintenance costs.

Cost-Benefit and ROI Analysis

Investing in the 190501-09-00-CN delivers long-term value. Its high accuracy minimizes false trips, which can cost thousands in lost production. The rugged 316L stainless steel case withstands harsh conditions, reducing replacement frequency. Furthermore, the transducer's internal electronics are isolated from the case, preventing ground loops that can corrupt signals and lead to costly misdiagnoses.

By catching vibration issues early, this transducer helps you perform maintenance only when needed, optimizing your maintenance budget and extending equipment life.

Applications and Use Cases

The 190501-09-00-CN is ideal for monitoring pumps, motors, fans, and other rotating machinery in industries such as oil and gas, power generation, and manufacturing. Its wide frequency response covers both low-speed and high-speed equipment, making it versatile for various applications.

For example, in a petrochemical plant, this transducer can detect bearing wear in a critical pump, allowing you to schedule repair during planned downtime instead of facing an emergency shutdown. This proactive approach saves both repair costs and lost production revenue.

Installation and Setup

Proper installation is key to accurate readings. The 190501-09-00-CN mounts via a 3/8-in 24 to 1/4-in NPT plate stud. Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) to ensure a secure fit. The transducer can be mounted at any angle, providing flexibility in tight spaces.

Connect using the MIL-C-5015 interface. Note the polarity: Pin A goes positive with respect to Pin B when velocity is from base to top. This ensures correct signal interpretation.

Maintenance and Reliability

Routine inspection of the transducer and its mounting is recommended to maintain reliability. Check for any signs of physical damage or loose mounting, which can affect readings. The 316L stainless steel case resists corrosion, but periodic cleaning with a soft cloth is advisable.

Given its robust design, the 190501-09-00-CN offers a long service life, reducing total cost of ownership. Its high shock limit (5000 g) and 100% condensing humidity tolerance make it suitable for demanding environments.

Compatibility and Integration

The 190501-09-00-CN is compatible with Bently Nevada monitoring systems that accept velocity transducer inputs. It can be integrated into existing vibration monitoring networks, providing seamless data for your condition monitoring software.
