Performance and Reliability
The 190501-08-00-00 delivers consistent performance with a broadband resolution of 0.229 mm/s (0.009 in/s) pk. Its base strain sensitivity is 0.43 mm/s/μstrain (0.017 in/s/μstrain), ensuring minimal interference from mechanical strain. Internal electronics are isolated from the case, reducing ground loop issues. With a maximum cable length of 305 meters (1,000 ft.) using part number 02173006, this transducer offers flexible installation options without signal degradation.
Industry Applications
In rotating equipment such as turbines, compressors, and pumps, the Bently Nevada 190501-08-00-00 provides critical vibration data. Its wide frequency response and high shock tolerance make it suitable for:
-
Predictive maintenance programs: Continuous monitoring helps detect early bearing wear and imbalance, reducing unplanned downtime.
-
Performance validation: Accurate velocity readings support machinery health assessments and commissioning tests.
-
Harsh environment installations: With 100% condensing humidity tolerance and 316L stainless steel construction, it withstands corrosive and wet conditions.
Installation and Setup
Mount the 190501-08-00-00 using the provided plate stud (3/8-in 24 to 1/2-in 20) with a 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, weatherproof connection. For optimal signal integrity, route the cable away from high-voltage lines and maintain the specified maximum cable length.
Maintenance and Longevity
Regularly inspect the transducer for physical damage and verify the mounting torque remains within specification. The sealed 316L stainless steel case protects internal components from moisture and contaminants, but periodic visual checks are recommended. With a storage temperature range of -40°C to +100°C, the unit remains stable during downtime.
Selection Guide
When integrating the Bently Nevada 190501-08-00-00 into your monitoring system, confirm your system's input impedance and power supply match the transducer's output bias voltage. For hazardous area applications, optional agency approvals (Ex ia IIC T4) are available for models with approval options 01 through 04.
