Bently Nevada 190501-13-00-CN - Velomitor Transducer

Bently Nevada Velomitor CT 190501-13-00-CN

Product Introduction

The Bently Nevada 190501-13-00-CN simplifies vibration monitoring with its quick disconnect stud. This Velomitor CT transducer measures absolute casing vibration on rotating machinery. You can install or remove it rapidly without special tools. Its 316L stainless steel construction handles harsh industrial environments from -40°C to +85°C.

Technical Specifications

Electrical Parameters

This sensor provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%. Frequency response spans 3.0 Hz to 900 Hz within ±1.0 dB. Alternatively, use 1.5 Hz to 1.0 kHz at ±3.0 dB for wider bandwidth. Amplitude linearity reaches ±2% up to 63.5 mm/s peak. Output bias voltage measures 10.1 Vdc ± 1.0 Vdc on Pin A referenced to Pin B.

Additionally, broadband noise sits at 0.229 mm/s peak. Base strain sensitivity is 0.43 mm/s/μstrain. Internal electronics isolate completely from the case. You can extend cable up to 305 meters (part number 02173006) with zero signal degradation.

Environmental Limits

Operating temperature ranges from -40°C to +85°C. Storage temperature extends from -40°C to +100°C. Maximum shock limit reaches 5000 g peak. Humidity tolerance includes 100% condensing conditions (non-submerged). Magnetic field susceptibility stays below 0.0068 mm/s/gauss at 50 gauss, 50-60 Hz.

Mechanical Data

The Bently Nevada 190501-13-00-CN weighs only 297 g. Case material is 316L stainless steel. Connector type is a 2-pin top-entry MIL-C-5015 made of 316L stainless steel. Mounting surface needs 33 mm diameter minimum. Height measures 82 mm. Apply 4.5 N-m ± 0.6 N-m mounting torque (40 in-lbf ± 5 in-lbf).

Furthermore, polarity is clearly defined. Pin A goes positive relative to Pin B when velocity directs from base to top. Any mounting angle works perfectly. The key feature is the quick disconnect stud for mounting hardware option 13.

Quick Disconnect Advantage

The mounting hardware option 13 sets this model apart. Instead of a fixed stud, you get a quick disconnect mechanism. This design allows rapid sensor replacement during machine operation. Downtime reduces significantly because you do not need to access the mounting base.

Specifically, the quick disconnect stud works with standard Bently Nevada mounting pads. You can pre-wire the connector assembly separately. Then simply snap the sensor into place. Removal takes seconds when calibration or replacement becomes necessary.

Performance Characteristics

Mounted resonant frequency is 9 kHz minimum with stud mounting. Note that quick disconnect versions may have slightly different resonant behavior. Transverse response stays below 5% of axial sensitivity. Temperature sensitivity varies from -8% to +5% typical across the operating range.

Dynamic output impedance sits under 400 Ω typically. The broadband threshold performs at 0.229 mm/s peak. Base strain sensitivity reaches 0.43 mm/s/μstrain. These specifications make the Bently Nevada 190501-13-00-CN suitable for pumps, fans, compressors, and turbines.

Installation Guidelines

First, install the quick disconnect mounting base on your machine. Surface must be clean and at least 33 mm diameter. Torque the base to 4.5 N-m ± 0.6 N-m. Next, connect your cable to the MIL-C-5015 connector on the sensor.

Then, align the Bently Nevada 190501-13-00-CN with the base. Push firmly until you hear a click. Pull gently to verify secure engagement. For removal, simply pull the release collar while lifting the sensor. No grounding is required because electronics isolate from the case.

Frequently Asked Questions (FAQ)

1. What does the -CN suffix mean on Bently Nevada 190501-13-00-CN?
The -CN indicates country-specific approval options. These vary by destination region. Contact your local Bently Nevada representative for exact certification details.

2. Can I use the quick disconnect in hazardous areas?
Yes, but check your specific approval code. The base approval options 01-04 cover hazardous locations. The quick disconnect mechanism itself does not affect safety ratings.

3. Is the quick disconnect as reliable as a stud mount?
Yes, for most industrial applications. However, extreme vibration environments may still benefit from permanent stud mounting. The quick disconnect is rated for standard rotating machinery.

4. How do I clean the Bently Nevada 190501-13-00-CN?
Use a soft, dry cloth only. Do not submerge the connector. Avoid high-pressure water jets. Keep the quick disconnect mechanism free from debris.

5. What is the shipping lead time?
In-stock items ship within 2 business days via Fedex, UPS, or DHL. Delivery typically takes 3 to 7 business days depending on your location.
