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

Product Introduction

When machinery vibration threatens operational uptime, the Bently Nevada 190501-07-00-01 Velomitor CT Velocity Transducer delivers reliable monitoring. This velocity transducer is designed for industrial environments where precise vibration measurement is critical. Manufactured in the U.S.A., it features a 316L stainless steel case and a MIL-C-5015 connection interface. The mounting hardware option includes a plate stud 3/8-in 24 to 3/8-in 24, ensuring secure installation. With agency approval option 01, it meets CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1) standards for hazardous locations.

Technical Specifications

The 190501-07-00-01 offers an electrical sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, providing accurate velocity readings. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, and extends to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) within ±3.0 dB. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, with dynamic output impedance under 400 Ω typical. The transducer can handle cable lengths up to 305 metres (1,000 ft.) using part number 02173006 without signal degradation. It operates in temperatures from -40°C to +85°C (-40°F to +185°F) and stores from -40°C to +100°C (-40°F to +212°F). The unit weighs less than 297 g (10.5 oz.) and has a height of 82 mm (3.2 in).

Industry Applications

This velocity transducer excels in rotating machinery monitoring, such as turbines, compressors, and pumps. In oil and gas facilities, the 190501-07-00-01 provides critical vibration data to prevent unplanned downtime. Its intrinsic safety certifications (Ex ia IIC T4, AEx ia IIC T4) make it suitable for hazardous environments like chemical plants. The transducer's transverse response is less than 5% of axial sensitivity, ensuring accurate readings even in complex vibration fields.

Installation & Setup Guidance

Mount the 190501-07-00-01 in any orientation, as it supports any angle. Use a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) for secure attachment. The mounting surface requires a diameter of 33 mm (1.3 in). Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. Ensure the cable length does not exceed 305 metres to maintain signal integrity. For hazardous area installations, follow drawing 167536.

Maintenance & Reliability

Regular inspection of the transducer and its cable is recommended to ensure consistent performance. The 316L stainless steel case provides corrosion resistance in harsh environments. The unit can withstand shock limits up to 5000 g pk maximum and operates in 100% condensing humidity (non-submerged). Its magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz, reducing interference in electrically noisy settings.

Selection Guide & Purchasing Advice

Before purchasing the 190501-07-00-01, verify your system's compatibility with the MIL-C-5015 connection interface. Confirm that the mounting hardware option (plate stud 3/8-in 24 to 3/8-in 24) fits your installation. For complete technical specifications, contact BluePLC Industrial.
