Bently Nevada 190501-11-00-00 Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-11-00-00 Velomitor CT Velocity Transducer delivers precise velocity measurements to protect your assets. This rugged sensor, manufactured in the U.S.A., is part of the trusted Bently Nevada family, engineered for continuous monitoring in demanding industrial environments. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it provides reliable data for predictive maintenance and machine protection.

Technical Specifications Breakdown

The 190501-11-00-00 offers a frequency response of 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. This range covers common vibration frequencies in rotating machinery. Its 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. The transducer withstands operating temperatures from -40°C to +85°C (-40°F to +185°F) and storage temperatures from -40°C to +100°C (-40°F to +212°F). It handles shock up to 5000 g pk maximum and operates in 100% condensing humidity (non-submerged). The case is made of 316L stainless steel, and the connector is a 2-pin 316L stainless steel MIL-C-5015, top-mounted. Weight is less than 297 g (10.5 oz) typical, with a height of 82 mm (3.2 in) and a mounting surface diameter of 33 mm (1.3 in). Mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf).

Industry Applications

This velocity transducer excels in monitoring critical rotating equipment such as turbines, compressors, pumps, and fans. In a petrochemical plant, for example, the 190501-11-00-00 can be mounted on a centrifugal compressor to detect early signs of imbalance or bearing wear. Its frequency response down to 3.0 Hz makes it suitable for low-speed machinery, while the 316L stainless steel case resists corrosion in harsh environments. Compared to typical piezoelectric accelerometers, this Velomitor CT provides a direct velocity output, simplifying integration with Bently Nevada monitoring systems.

Installation & Setup Guidance

Mount the transducer using the provided plate stud (3/8-in 24 to 1/4-in 28) with a torque of 4.5 N-m ± 0.6 N-m. The transducer can be mounted at any angle. Ensure the mounting surface is clean and flat (33 mm diameter minimum). Connect via the MIL-C-5015 interface; cable length can extend up to 305 metres (1,000 ft) using part number 02173006 without signal degradation. Polarity is critical: Pin A goes positive with respect to Pin B when velocity is from base to top. Grounding is internal, with electronics isolated from the case.

Maintenance & Reliability

With no moving parts and a hermetically sealed 316L stainless steel case, the 190501-11-00-00 requires minimal maintenance. Periodic inspection of the cable and connector for damage is recommended. The transducer's temperature sensitivity is -8% to +5% typical over the operating range, ensuring stable performance. Its transverse response is less than 5% of axial sensitivity, and amplitude linearity is ±2% to 63.5 mm/s pk (2.5 in/s pk). These characteristics contribute to long service life and reduced total cost of ownership.

Selection Guide & Purchasing Advice

Before ordering, verify that the mounting hardware option (1 1 Plate Stud 3/8-in 24 to 1/4-in 28) and connection option (MIL-C-5015) match your installation requirements. The agency approval option for this unit is 00 (no approvals). For applications requiring intrinsic safety, consider models with approval options 01 through 04.
