Bently Nevada 190501-12-99-00 Velomitor CT Velocity Transducer Overview

Product Introduction

The industrial landscape has evolved significantly, with predictive maintenance becoming a cornerstone of operational efficiency. The Bently Nevada 190501-12-99-00 Velomitor CT Velocity Transducer represents a key component in this shift, offering precise vibration measurement for rotating machinery. Manufactured in the U.S.A., this transducer is part of the trusted Bently Nevada series, known for reliability in harsh environments.

Technical Specifications Breakdown

The 190501-12-99-00 delivers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity readings. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, and extends from 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) within ±3.0 dB, covering a wide range of machine speeds. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced between Pin A and Pin B, while the dynamic output impedance remains below 400 Ω typical. These parameters make it suitable for continuous monitoring in demanding applications.

Industry Applications

In the oil and gas sector, the 190501-12-99-00 monitors critical pumps and compressors, detecting early signs of imbalance or misalignment. For power generation, it tracks turbine vibrations, helping to prevent unplanned outages. The transducer's robust design, with a case material of 316L stainless steel and an operating temperature range of -40°C to +85°C, ensures reliable performance in extreme conditions.

Installation & Setup Guidance

Mounting the transducer requires a plate stud of 3/8-in 24 to M8x1, as specified by the mounting hardware option. The included 32-foot cable simplifies connection to monitoring systems. Ensure the mounting surface is clean and flat, and apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be oriented at any angle, offering flexibility in placement. Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top.

Maintenance & Reliability

Regular inspection of the cable and connector is recommended, especially in high-vibration environments. The 316L stainless steel construction resists corrosion, extending service life. With a shock limit of 5000 g pk maximum and a humidity limit of 100% condensing (non-submerged), this transducer is built for durability. Periodic verification of sensitivity and frequency response ensures continued accuracy.

Selection Guide & Purchasing Advice

When selecting the 190501-12-99-00, verify compatibility with your monitoring system, particularly the cable length—up to 305 metres (1,000 ft.) of cable (part number 02173006) is supported without signal degradation. For applications requiring agency approvals, consider options 01 through 04, which offer intrinsic safety certifications.
