190501-13-00-CN | Bently Nevada Velomitor CT Velocity Transducer 3.94 mV/mm/s

Introduction to the 190501-13-00-CN Bently Nevada Velomitor CT Velocity Transducer

When machinery vibration threatens uptime, the 190501-13-00-CN Bently Nevada Velomitor CT Velocity Transducer provides reliable measurement. This sensor converts mechanical velocity into an electrical signal for condition monitoring. It is designed for harsh industrial environments and offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% accuracy. The transducer supports a frequency response from 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) at ±3.0 dB. This makes it suitable for rotating machinery such as turbines, compressors, and pumps.

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%.
• Frequency response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB.
• Operating temperature range: -40°C to +85°C (-40°F to +185°F).
• Output bias voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Mounted resonant frequency: 9 kHz minimum (stud mounted, except quick disconnect).
• Maximum cable length: 305 metres (1,000 ft.) with cable part number 02173006.
• Case material: 316L stainless steel for corrosion resistance.
• Weight: less than 297 g (10.5 oz) typical.

A standout specification is the 190501-13-00-CN’s wide operating temperature range of -40°C to +85°C. This ensures stable performance in extreme conditions, from cold storage to hot process areas. The transducer also features a transverse response less than 5% of axial sensitivity, minimizing cross-axis errors.

Applications and Use Cases for the 190501-13-00-CN

The 190501-13-00-CN is ideal for vibration monitoring on critical rotating equipment. For example, it can be installed on steam turbines to detect early bearing wear. Similarly, it works well on centrifugal compressors where high-frequency vibration indicates imbalance. The transducer’s 316L stainless steel case withstands corrosive atmospheres in chemical plants. Moreover, its intrinsic safety approvals (Ex ia IIC T4) allow use in hazardous areas such as oil refineries. This versatility makes it a top choice for reliability engineers.

Installation and Setup Guide

Mount the 190501-13-00-CN on a flat surface with a 33 mm diameter (1.3 in) mounting area. Use the provided quick disconnect stud option for easy installation. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure proper coupling. The transducer can be oriented in any angle. Connect the 2-pin 316L stainless steel MIL-C-5015 connector. Pin A goes positive with respect to Pin B when velocity is from base to top. For hazardous locations, follow installation drawing 167536. Keep cable length within 305 metres (1,000 ft.) to avoid signal degradation.

Maintenance and Reliability

Routine inspection of the 190501-13-00-CN ensures long-term accuracy. Check the mounting surface for corrosion or debris annually. Verify the output bias voltage (10.1 Vdc ± 1.0 Vdc) during calibration cycles. The transducer’s 316L stainless steel case resists environmental damage. Its internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk, it survives severe impacts. For cost-benefit analysis, this reliability reduces unplanned downtime and replacement costs.
