Industry Applications
The 190501-01-00-00 excels in rotating machinery monitoring across industries. Use it on pumps, motors, fans, compressors, and turbines to track vibration velocity. Its wide frequency response captures both low-speed and high-speed machine dynamics, enabling early detection of imbalance, misalignment, and bearing wear. The rugged 316L stainless steel case withstands harsh process environments, making it suitable for chemical plants, refineries, and power generation facilities.
Installation & Setup
Mount the transducer using the 3/8-in-24 stud provided (Mounting Hardware Option 01). Ensure the mounting surface is clean and flat, and apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The MIL-C-5015 connection interface (Connection Option 00) accepts standard 2-pin connectors. For optimal performance, maintain the maximum cable length of 305 meters (1,000 ft) using the specified cable part number 02173006. Verify polarity: Pin A goes positive with respect to Pin B when velocity is from base to top. The transducer can be mounted in any orientation, simplifying installation in tight spaces.
Maintenance & Reliability
The 190501-01-00-00 requires minimal maintenance due to its solid-state design and 316L stainless steel construction. Periodically inspect the mounting stud for tightness and check the cable for damage, especially in high-vibration areas. The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk and an operating temperature range of -40°C to +85°C, this transducer delivers long-term reliability, reducing total cost of ownership.
Selection Guide
When ordering, verify the exact part number 190501-01-00-00 to ensure you receive the correct configuration: stud mounting, MIL-C-5015 connector, and no agency approvals. If you require intrinsically safe certification, consider the 190501 with Agency Approval Options 01 through 04.
