Bently Nevada 190501-12-00-01 Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-12-00-01 Velomitor CT Velocity Transducer provides accurate, reliable measurement. This piezoelectric velocity sensor converts mechanical motion into an electrical signal proportional to velocity, enabling early detection of bearing wear, imbalance, and misalignment in rotating equipment. Designed for harsh industrial environments, it delivers consistent performance across a wide temperature range and meets stringent global safety standards.

Technical Specifications Breakdown

The 190501-12-00-01 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise vibration measurement. Its frequency response covers 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, extending to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) within ±3.0 dB, suitable for most industrial machinery. The output bias voltage is 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B), and the dynamic output impedance is less than 400 Ω typical. Amplitude linearity is ±2% to 63.5 mm/s pk (2.5 in/s pk), ensuring accurate readings up to high vibration levels. The mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect).

Industry Applications

This transducer excels in monitoring critical rotating assets such as pumps, compressors, turbines, and fans in oil and gas, power generation, and chemical processing plants. Its intrinsic safety certifications (ATEX/IECEx/CSA Class I, Zone 0/1) allow installation in explosive atmospheres, making it ideal for upstream and downstream hydrocarbon facilities. Compared to similar velocity transducers, the 190501-12-00-01 offers a higher sensitivity and broader frequency response, enabling earlier fault detection and reduced false alarms.

Installation & Setup Guidance

Mount the transducer using the provided plate stud 3/8-in 24 to M8x1 hardware with a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The 2-pin 316L stainless steel MIL-C-5015 top connector ensures a secure, corrosion-resistant connection. The transducer can be oriented at any angle, and polarity is defined as Pin A going positive with respect to Pin B when velocity is from base to top. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 without signal degradation.

Maintenance & Reliability

With a 316L stainless steel case and internal electronics isolated from the case, the 190501-12-00-01 withstands corrosive environments and high humidity (100% condensing, non-submerged). The shock limit is 5000 g pk maximum, ensuring survival during severe events. Routine inspection should focus on cable integrity and connector cleanliness. The transducer operates from -40°C to +85°C and stores from -40°C to +100°C, providing long-term reliability in extreme conditions.

Buying Guide & Selection Advice

When selecting the Bently Nevada 190501-12-00-01, verify that the agency approval option (01) matches your area classification (CSA/NRTL/C Class I, Division 1; ATEX/IECEx/CSA Class I, Zone 0/1). Confirm the mounting hardware option (12 = plate stud 3/8-in 24 to M8x1) suits your installation.
