• Mounting Surface: 33 mm diameter (1.3 in diameter).
• Height: 82 mm (3.2 in).
• Case Material: 316L stainless steel.
• Connector: 2-pin 316L stainless steel MIL-C5015, top.
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).
• Polarity: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer.
• Mounting Angle: Any orientation.

The 316L stainless steel case resists corrosion. The MIL-C-5015 connector provides a secure, reliable electrical connection. Moreover, the any-orientation mounting simplifies installation in tight spaces.

Applications and Use Cases

The 190501-01-00-00 is ideal for vibration monitoring on rotating machinery. Typical applications include pumps, motors, fans, and compressors. Its frequency response covers a wide range of operating speeds. Therefore, it works well on both low-speed and high-speed equipment. The transducer's robust design also suits harsh industrial environments. In addition, the long cable length capability allows flexible placement of monitoring electronics.

Installation and Setup

Proper installation ensures accurate measurements. The 190501-01-00-00 mounts via a 3/8-in 24 stud. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m. This ensures a secure and stable mount. Connect the MIL-C-5015 connector to the mating cable. Follow the polarity marking: Pin A positive with respect to Pin B. The transducer can be mounted in any orientation. Consequently, it adapts to various machine geometries.

Maintenance and Reliability

Routine maintenance is minimal. The sealed stainless steel construction protects internal components. Periodically inspect the mounting stud and connector for tightness. Also, check the cable for damage. The transducer's low base strain sensitivity reduces errors from mounting stress. Therefore, it delivers consistent performance over time. This reliability minimizes downtime and maintenance costs.

Comparison with Similar Products

Compared to other velocity transducers, the 190501-01-00-00 offers distinct advantages. Its sensitivity of 3.94 mV/mm/s is standard for industrial applications. The frequency response of 3.0 Hz to 900 Hz covers most machinery vibration frequencies. Additionally, the 316L stainless steel case exceeds many competitors' aluminum housings. The MIL-C-5015 connector is a rugged, proven interface. These features make it a preferred choice for critical machinery protection.
