The transducer is housed in a 316L stainless steel case. It weighs less than 297 g (10.5 oz.). The mounting surface is 33 mm diameter (1.3 in). The height is 82 mm (3.2 in). The connector is a 2-pin 316L stainless steel MIL-C-5015, top-mounted. Mounting torque is 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).

Applications and Use Cases

This velocity transducer suits machinery protection systems. It monitors vibration on pumps, fans, compressors, and turbines. The wide frequency response captures both low-speed and high-speed machine dynamics. The transducer's internal electronics are isolated from the case, reducing ground loop issues. For engineers seeking reliable vibration data, the 190501-08-00-00 delivers consistent performance.

Installation and Setup

Proper mounting is essential for accurate measurements. The mounting hardware option is a plate stud 3/8-in 24 to 1/2-in 20. The transducer can be mounted in any orientation. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m. Ensure the mounting surface is clean and flat. The MIL-C-5015 connection interface provides a secure electrical connection. Maximum cable length is 305 metres (1,000 ft.) with the specified cable part number.

Maintenance and Reliability

The 190501-08-00-00 is designed for long service life. Its 316L stainless steel construction resists corrosion. The transducer has no moving parts, reducing wear. Periodic inspection of the mounting and cable integrity is recommended. Verify the output bias voltage periodically. This helps ensure the transducer remains within specification. The unit operates over a wide temperature range, making it suitable for harsh environments.

Compatibility and Integration

The transducer's output is a standard velocity signal. It can interface with Bently Nevada monitoring systems. The MIL-C-5015 connector is a common industrial standard. The internal electronics are isolated from the case, which simplifies grounding. This design minimizes interference in industrial settings.

Troubleshooting and Common Issues

If the output signal is missing or erratic, check the cable connection first. Ensure the mounting torque is correct. Verify that the transducer is not subjected to excessive shock beyond its 5000 g limit. If the signal is noisy, check for magnetic field interference. The transducer's susceptibility is <0.0068 mm/s/gauss at 50 gauss. For persistent issues, consult the Bently Nevada manual or contact Petro Auto Tech.
