Key Features and Technical Specifications

The 190501-00-00-04 offers a range of specifications that make it a versatile choice. Here are the core parameters:

• Product Type: Velomitor CT Velocity Transducer
• 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; 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB
• Dynamic Output Impedance: <400 Ω typical
• 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)
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Case Material: 316L stainless steel
• Weight: <297 g (10.5 oz.), typical

One distinctive feature is the broadband base strain sensitivity of 0.43 mm/s/μstrain (0.017 in/s/μstrain). This means the transducer minimizes false readings from mechanical strain, ensuring accurate vibration data. As a result, you can rely on the 190501-00-00-04 for precise diagnostics.

Real-World Applications

The 190501-00-00-04 is suitable for monitoring pumps, motors, fans, and other rotating machinery. For example, in a petrochemical plant, this transducer can detect early bearing wear, allowing you to plan maintenance without interrupting production. Similarly, in power generation, it helps monitor turbine vibration, contributing to operational safety.

Because the transducer is intrinsically safe (Ex ia IIC T4), it is approved for hazardous areas, including Class I, Division 1 and Zone 0/1. This makes it a dependable choice for oil and gas, chemical, and other explosive environments.

Installation and Mounting

Proper installation is essential for accurate readings. The 190501-00-00-04 features a 2-pin 316L stainless steel MIL-C-5015 connection interface. The mounting surface is 33 mm in diameter, and the height is 82 mm. Use the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to secure the transducer.

Additionally, the transducer can be mounted in any orientation, offering flexibility in tight spaces. The internal electronics are isolated from the case, reducing ground loop issues. Always follow the manufacturer's installation drawing (167536) for hazardous area installations.

Maintenance and Reliability

Routine inspection ensures long-term performance. Check the cable and connector for damage, and verify that the mounting remains tight. The 190501-00-00-04 is built with 316L stainless steel, offering excellent corrosion resistance. Its shock limit is 5000 g pk, and it can operate in 100% condensing humidity (non-submerged).

With proper care, this transducer provides reliable service for years. Its robust design minimizes the need for frequent replacements, contributing to lower total cost of ownership.

Compatibility and Integration

The 190501-00-00-04 is designed to work with Bently Nevada monitoring systems. It supports cable lengths up to 305 metres (1,000 ft.) with part number 02173006, without signal degradation. This flexibility allows you to place the transducer far from the monitoring equipment.

For new installations or retrofits, the transducer's standard MIL-C-5015 connector simplifies wiring. Always verify compatibility with your existing system before ordering.
