190501-07-00-01 | Bently Nevada Velomitor CT Velocity Transducer

190501-07-00-01 Velomitor CT Velocity Transducer Overview

When machinery vibration threatens uptime, the 190501-07-00-01 from Bently Nevada provides precise, continuous velocity measurement. This Velomitor CT transducer is engineered for industrial rotating equipment, offering a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%. Its rugged 316L stainless steel case and MIL-C-5015 connection interface make it suitable for harsh environments. As a maintenance engineer, you need reliable data to plan repairs—this transducer delivers exactly that.

Key Features and Technical Specifications

The 190501-07-00-01 is built to perform under demanding conditions. Below are the critical specifications you can rely on:

• 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.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.
• Broadband Noise: 0.229 mm/s (0.009 in/s) pk.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain).
• Operating Temperature: -40°C to +85°C (-40°F to +185°F).
• Shock Limit: 5000 g pk, maximum.
• Humidity Limit: 100% condensing, non-submerged.
• Magnetic Field Susceptibility: <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60 Hz.
• Weight: 0.297 kg (10.5 oz), typical.

These specs ensure accurate vibration measurement even in challenging industrial settings. The transducer's internal electronics are isolated from the case, reducing ground loop issues.

Applications and Use Cases

The 190501-07-00-01 is ideal for monitoring pumps, motors, fans, and other rotating machinery. Its wide frequency response captures both low-speed and high-speed vibrations, making it versatile across different equipment types. For example, in a paper mill, you can mount it on a dryer roll bearing housing to detect imbalance or misalignment early. Similarly, in a petrochemical plant, it helps monitor compressor health, preventing unplanned shutdowns. Because it operates from -40°C to +85°C, it suits outdoor installations in extreme climates.

Installation and Setup

Proper mounting is crucial for accurate readings. The 190501-07-00-01 comes with a plate stud mounting option (3/8-in 24 to 3/8-in 24). 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 in any orientation, giving you flexibility in tight spaces. Use the specified cable (part number 02173006) up to 305 meters (1,000 ft) without signal degradation. Always follow the manufacturer's installation drawing (167536) for hazardous area setups.

Maintenance and Reliability

Regular inspection of the transducer and its mounting is essential for long-term reliability. Check the mounting stud for tightness periodically, as vibration can loosen it over time. Verify the cable connections are secure and free from damage. The 316L stainless steel case resists corrosion, but a visual check helps catch issues early. By monitoring the output bias voltage (10.1 Vdc ± 1.0 Vdc), you can quickly detect if the internal electronics are functioning correctly. This proactive approach minimizes downtime and extends equipment life.

Compatibility and Integration

The 190501-07-00-01 integrates seamlessly with Bently Nevada monitoring systems. Its MIL-C-5015 connection interface ensures a standardized hookup. The transducer's low output impedance (<400 Ω) allows it to drive long cables without signal loss. It is compatible with most vibration monitoring racks and data acquisition systems that accept velocity transducer inputs. For hazardous area installations, the unit carries agency approvals including CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1).
