Bently Nevada Velomitor CT 190501-00-00-00

Bently Nevada Velomitor CT 190501-00-00-00

Product Introduction

The Bently Nevada 190501-00-00-00 offers essential casing vibration measurement. This Velomitor CT transducer comes without a mounting stud for maximum flexibility. You can purchase your preferred mounting hardware separately. Its 316L stainless steel body withstands temperatures from -40°C to +85°C. Many facilities choose this base model for non-hazardous general-purpose monitoring.

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. For broader coverage, use 1.5 Hz to 1.0 kHz at ±3.0 dB. 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 no signal loss.

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 190501-00-00-00 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 difference is mounting hardware option 00: no stud included.

Performance Characteristics

Mounted resonant frequency is 9 kHz minimum with proper stud mounting. 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 190501-00-00-00 suitable for pumps, fans, compressors, and general machinery monitoring. Remember that final performance depends on correct stud installation.

Installation Guidelines

First, obtain a compatible mounting stud for your application. Clean the mounting surface thoroughly. Minimum diameter required is 33 mm. Next, install the stud into your machine surface. Torque it to 4.5 N-m ± 0.6 N-m.

Then, connect Pin A to your positive signal input. Pin B serves as the reference. Screw the Bently Nevada 190501-00-00-00 onto the installed stud. Apply the same torque value. Grounding is unnecessary because electronics isolate from the case. Always verify output bias voltage before final commissioning.

Frequently Asked Questions (FAQ)

1. Why would I choose the Bently Nevada 190501-00-00-00 over other options?
This base model costs less when you already have compatible mounting hardware. It also gives you freedom to select third-party studs or custom adapters.

2. What studs work with this transducer?
Any stud with 3/8-in 24 UNF or M8x1 thread works. Bently Nevada offers options 11, 12, and 13. Ensure the stud length does not bottom out inside the sensor.

3. Does no stud affect the performance?
Performance remains identical once you install a proper stud. The transducer itself has the same internal design. Only the included accessories differ.

4. Can I use the Bently Nevada 190501-00-00-00 in hazardous areas?
No, because approval option 00 means no certifications. For hazardous locations, select options 01 through 04 with appropriate safety approvals.

5. What is the typical shipping 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.
