Environmental Durability and Mechanical Design

The 190501-09-00-CN is built to withstand harsh industrial environments. Its environmental limits include:

• Operating Temperature: -40°C to +85°C (-40°F to +185°F).
• Storage Temperature: -40°C to +100°C (-40°F to +212°F).
• Shock Limit: 5000 g pk, maximum.
• Humidity Limit: 100% condensing, non-submerged.
• Magnetic Field Susceptibility: <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60Hz.

Mechanically, the transducer features a 316L stainless steel case and connector, ensuring corrosion resistance. The mounting surface is 33 mm diameter (1.3 in), and the height is 82 mm (3.2 in). The mounting hardware option is a plate stud 3/8-in 24 to 1/4-in NPT, and the connection option is a MIL-C-5015 interface. The mounting torque is 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The polarity is defined as Pin A going positive with respect to Pin B when velocity is from base to top. The transducer can be mounted in any orientation.

Applications and Use Cases

The 190501-09-00-CN is ideal for monitoring vibration on rotating equipment such as pumps, motors, fans, and compressors. Its wide frequency response and high shock limit make it suitable for both normal and demanding applications. By providing accurate velocity data, it enables predictive maintenance strategies that prevent catastrophic failures.

Furthermore, the transducer's internal electronics are isolated from the case, reducing the risk of ground loops. This feature enhances signal integrity, which is critical for reliable condition monitoring. The maximum cable length of 305 meters allows flexible installation in large facilities.

Installation and Setup

Proper installation is essential for optimal performance. The 190501-09-00-CN should be mounted securely using the specified plate stud. Ensure the mounting surface is clean and flat to achieve the recommended torque of 4.5 N-m ± 0.6 N-m. The transducer can be oriented in any direction, simplifying installation in tight spaces.

When connecting the MIL-C-5015 interface, verify that Pin A and Pin B are correctly wired to match the polarity requirements. Use the recommended cable (part number 02173006) to maintain signal quality over long distances.

Maintenance and Reliability

The 190501-09-00-CN is designed for long-term reliability with minimal maintenance. Its 316L stainless steel construction resists corrosion, and the sealed design protects internal components from moisture and contaminants. Regular inspection of the mounting and cable connections is recommended to ensure consistent performance.

Given its robust design, the transducer can operate in temperatures from -40°C to +85°C, making it suitable for extreme environments. The shock limit of 5000 g ensures it can withstand occasional impacts without damage.

Compatibility and Integration

The 190501-09-00-CN is compatible with Bently Nevada monitoring systems that accept velocity transducer inputs. Its standard sensitivity and output bias voltage allow straightforward integration into existing monitoring architectures. The MIL-C-5015 connector ensures a secure and reliable electrical connection.
