Bently Nevada 190501-10-00-02 Velomitor CT Velocity Transducer Overview

Product Introduction

When a critical rotating machine in a refinery begins exhibiting subtle vibration changes, the Bently Nevada 190501-10-00-02 Velomitor CT Velocity Transducer provides the precise, reliable measurement needed to diagnose and prevent failure. This velocity transducer is designed for continuous monitoring in harsh industrial environments, offering high sensitivity and robust construction.

Technical Specifications Breakdown

The 190501-10-00-02 delivers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity measurements for early fault detection. Its frequency response covers 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB, making it suitable for a wide variety of machinery speeds. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B, and the dynamic output impedance is less than 400 Ω typical. With a mounted resonant frequency of 9 kHz minimum (stud mounted, except quick disconnect), the transducer avoids resonance interference in most applications. The unit weighs 0.297 kg and is constructed with a 316L stainless steel case for corrosion resistance.

Industry Applications

This velocity transducer excels in applications such as monitoring centrifugal pumps, compressors, fans, and turbines in oil and gas, petrochemical, and power generation facilities. Its intrinsic safety certifications—Ex ia IIC T4 and AEx ia IIC T4—allow installation in hazardous areas classified as Class I, Division 1, Groups A, B, C, D, as well as Class II and Class III environments. The 190501-10-00-02 also carries ATEX/IECEx/CSA (Class I, Zone 0/1) approvals, ensuring compliance with global safety standards. By providing early warning of bearing wear or imbalance, this transducer helps reduce unplanned downtime and maintenance costs.

Installation & Setup Guidance

Mount the transducer using the included plate stud M6x1 to M6x1 with 3/8-24 adapter. The mounting torque should be 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be installed at any orientation, and the mounting surface requires a 33 mm diameter (1.3 in diameter). The 2-pin 316L stainless steel MIL-C-5015 top connector provides a secure, reliable connection. When wiring, note that Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. For optimal signal integrity, use cable part number 02173006 up to 305 metres (1,000 ft.) without signal degradation.

Maintenance & Reliability

The 190501-10-00-02 is built for long-term reliability in demanding conditions. Its internal electronics are isolated from the case, reducing ground loop issues. The transducer withstands a shock limit of 5000 g pk maximum and operates in 100% condensing humidity (non-submerged). Magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz. Regular inspection of the cable and connector for damage, and verification of output bias voltage, will ensure continued accurate performance. The operating temperature range is -40°C to +85°C (-40°F to +185°F), with storage from -40°C to +100°C (-40°F to +212°F).

Selection Guide & Purchasing Advice

When selecting the 190501-10-00-02, verify that the agency approval option (02) matches your area classification requirements—CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1). Confirm the mounting hardware option (plate stud M6x1 to M6x1 with 3/8-24 adapter) and connection option (MIL-C-5015) suit your installation.
