Key Features
The 200350-01-00-00 offers several advantages for vibration monitoring applications.
Wide Frequency Range:
The sensor measures from 30 to 600,000 cpm (0.5 to 10,000 Hz). Consequently, it captures both low and high frequency vibrations effectively.
High Sensitivity:
With 100 mV/g ±20% output, it detects small vibration changes. Therefore, it suits predictive maintenance programs.
IP68 Environmental Rating:
The welded hermetic sealing provides IP68 protection. As a result, the sensor operates reliably in wet and condensing environments.
Shear Sensing Geometry:
The ceramic shear element offers excellent temperature stability. Moreover, it reduces base strain sensitivity for more accurate measurements.
High Shock Survivability:
The sensor withstands 5,000 g peak shock. Hence, it survives harsh machine start-up and fault conditions without damage.
Electrical Isolation:
Case isolation exceeds 10⁸ ohms. Therefore, ground loops are prevented in monitoring systems.
Stainless Steel Mounting Stud:
The -01 option includes a 1/4-28 to M6 x 1.00 stainless steel stud. Thus, it adapts to both imperial and metric mounting holes.
Typical Applications
The 200350-01-00-00 suits various vibration monitoring applications.
Case-mounted vibration monitoring on pumps and fans.
Bearing housing measurement on compressors.
Machine condition monitoring in industrial plants.
Predictive maintenance programs.
Vibration data collection for spectrum analysis.
Installation Guidelines
Install the 200350-01-00-00 using the included 1/4-28 to M6 x 1.00 stainless steel mounting stud. First, clean the mounting surface thoroughly. Then, screw the stud into the machine's threaded hole. For metric holes, use the M6 side. For imperial holes, use the 1/4-28 side.
After the stud is secured, mount the sensor onto the stud. Apply mounting torque between 2 and 5 ft-lb (2.7 to 6.8 N-m). Do not overtighten. Connect the 2-pin Mil-C-5015 connector to a compatible constant current power supply. Supply 18-28 VDC at 2-20 mA. The output bias voltage will settle within 8-12 VDC after approximately 2 seconds.
