Industry Applications
This transducer excels in monitoring critical rotating equipment such as turbines, compressors, and pumps. In a petrochemical plant, its high sensitivity and wide frequency range detect early bearing wear and imbalance. The 190501-04-00-CN's rugged construction and intrinsic safety ratings make it ideal for hazardous locations, reducing the risk of catastrophic failures.
Installation & Setup Guidance
Mount the transducer using the provided stud M6x1 with 3/8-in 24 adapter. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The sensor can be mounted at any angle. Connect via the 2-pin 316L stainless steel MIL-C-5015 connector. Ensure cable length does not exceed 305 metres (1,000 ft.) of part number 02173006 cable to maintain signal integrity. For hazardous area installations, follow drawing 167536.
Maintenance & Reliability
Periodically inspect the transducer and cable for physical damage. Verify output bias voltage (10.1 Vdc ± 1.0 Vdc) during routine checks. The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk and 100% condensing humidity tolerance, this sensor delivers long-term reliability in tough conditions.
Compatibility & Integration
The 190501-04-00-CN integrates seamlessly with Bently Nevada monitoring systems. Its dynamic output impedance (<400 Ω typical) and broadband noise floor (0.229 mm/s pk) ensure clean signals for data acquisition. The MIL-C-5015 interface simplifies connection to compatible cabling and junction boxes.
