• Magnetic Field Susceptibility: <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60 Hz.

The mechanical construction is equally robust. The case is made of 316L stainless steel, providing excellent corrosion resistance. The connector is a 2-pin 316L stainless steel MIL-C-5015 type, located on top. The mounting surface has a 33 mm diameter, and the height is 82 mm. The transducer weighs less than 297 g (10.5 oz), making it lightweight yet durable. The mounting torque is specified at 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf).

Applications and Use Cases

The 190501-04-00-CN is ideal for monitoring rotating machinery such as pumps, motors, fans, and compressors. Its frequency response covers a broad range, making it suitable for both low-speed and high-speed equipment. For example, in a paper mill, you can mount the transducer on a dryer roll to detect bearing wear early. Similarly, in a power plant, it can monitor turbine vibrations to prevent unplanned outages. The transducer's rugged design ensures reliable operation in these demanding settings.

Installation and Mounting

Proper installation is critical for accurate measurements. The 190501-04-00-CN comes with a stud M6x1 mounting hardware option, including a 3/8-in 24 adapter. This allows flexible mounting on various machine surfaces. The connection interface is MIL-C-5015, ensuring a secure and standardized electrical connection. When mounting, apply the specified torque of 4.5 N-m ± 0.6 N-m to ensure a solid mechanical bond. The transducer can be oriented in any direction, simplifying installation in tight spaces. Always follow the manufacturer's guidelines for surface preparation and mounting to achieve optimal performance.

Maintenance and Reliability

To maintain long-term reliability, periodic inspection is recommended. Check the mounting integrity and cable condition regularly. The 316L stainless steel case resists corrosion, but environmental factors like chemical exposure can still affect performance. Therefore, verify the transducer's operation periodically by comparing its output with a known reference. If any anomaly is detected, consult the manufacturer's manual or contact Petro Auto Tech for guidance. Regular maintenance ensures the 190501-04-00-CN continues to provide accurate data, minimizing downtime and extending service life.
