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

What Is the Bently Nevada 190501-00-00-00?

When critical machinery begins to vibrate unexpectedly, do you have the right sensor to detect early signs of failure? The Bently Nevada 190501-00-00-00 Velomitor CT Velocity Transducer provides accurate velocity measurements for rotating equipment. Manufactured by Bently Nevada in the U.S.A., this transducer is designed for industrial environments where reliability is non-negotiable. Its compact design and robust 316L stainless steel case make it suitable for harsh conditions.

Technical Specifications

The 190501-00-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise velocity readings. Its frequency response covers 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB. 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. This transducer operates over a wide temperature range from -40°C to +85°C (-40°F to +185°F) and can be stored from -40°C to +100°C (-40°F to +212°F). It withstands shock up to 5000 g pk and operates in 100% condensing humidity (non-submerged). The unit weighs less than 297 g (10.5 oz.) and has a mounting surface diameter of 33 mm (1.3 in) and height of 82 mm (3.2 in). The case material is 316L stainless steel, and the connector is a 2-pin 316L stainless steel MIL-C-5015 top-mounted type. Mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. The transducer can be mounted in any orientation.

Industry Applications

This velocity transducer is ideal for monitoring vibrations in pumps, fans, compressors, and turbines. In a typical petrochemical plant, the 190501-00-00-00 helps detect imbalance or misalignment early, reducing unplanned downtime. Its wide frequency response and high sensitivity make it suitable for both low-speed and high-speed rotating machinery. The robust stainless steel construction ensures long service life even in corrosive environments.

Installation & Setup Guidance

Mount the transducer on a clean, flat surface using the specified mounting torque of 4.5 N-m ± 0.6 N-m. The unit can be installed in any orientation, but ensure the mounting surface is free of debris. Use the MIL-C-5015 connection interface for reliable signal transmission. For optimal performance, keep cable length within 305 metres (1,000 ft.) using part number 02173006 cable to avoid signal degradation. Grounding is internal, with electronics isolated from the case.

Maintenance & Reliability

Regularly inspect the transducer and cable for physical damage. The 316L stainless steel case resists corrosion, but check the connector for moisture ingress. The transducer operates reliably in condensing humidity and high magnetic fields (magnetic field susceptibility less than 0.0068 mm/s/gauss at 50 gauss, 50-60 Hz). No routine calibration is required, but periodic verification of output bias voltage ensures consistent performance.

Selection Guide & Purchasing Advice

Before ordering, confirm that the 190501-00-00-00 matches your application requirements. This model comes with no mounting stud and no agency approvals (option 00). If you need intrinsic safety certifications (Ex ia IIC T4 or AEx ia IIC T4), consider ordering agency approval options 01 through 04.
