Key Features

The 200350-01-00-01 offers several advantages for vibration monitoring.

High Sensitivity:
Provides 100 mV/g ±20% output. Therefore, it detects both low and high amplitude vibrations effectively.

Wide Frequency Range:
Measures from 30 to 600,000 cpm (0.5 to 10,000 Hz). Consequently, it captures a broad spectrum of machinery vibrations.

Rugged Stainless Steel Housing:
The housing material is stainless steel with welded hermetic sealing. Thus, it resists corrosion and moisture ingress.

IP68 Enclosure Rating:
Fully protected against dust and continuous immersion. Hence, it suits submersible and wash-down applications.

Hazardous Area Approvals:
CSA, ATEX, and IECEx certified for explosive atmospheres. As a result, global installation is simplified.

Wide Temperature Range:
Operates from -54°C to +121°C (-65°F to +250°F). Therefore, it works in extreme climate conditions.

High Shock Survivability:
Withstands 5,000 g peak shock without damage. Consequently, it survives harsh machine start-up and trip events.

Low Transverse Sensitivity:
≤7% sensitivity to cross-axis vibrations. Hence, measurements accurately reflect the intended axis.

Excellent Amplitude Linearity:
±1% linearity ensures accurate readings across the measurement range. Thus, reliable protection decisions are supported.

Typical Applications

The 200350-01-00-01 suits various vibration monitoring applications.

• Gearbox vibration monitoring on compressors.

• Pump bearing vibration measurement.

• Fan and blower imbalance detection.

• Turbomachinery casing vibration.

• Offshore platform equipment monitoring.

Installation Guidelines

Install the 200350-01-00-01 directly on the machine surface. First, prepare a clean, flat mounting surface. Then, apply the ¼-28 to M6 x 1.00 stainless steel mounting stud. Tighten to 2 to 5 ft-lb (2.7 to 6.8 N-m) maximum torque.

Next, connect the 2-pin Mil-C-5015 connector to the top of the sensor. Apply constant current excitation of 2 to 20 mA at 18 to 28 VDC. The output bias voltage will settle within 2.0 seconds.

For hazardous area installations, follow CSA, ATEX, or IECEx wiring practices. The sensor is IP68 rated, so it can be installed in wet or condensing environments. However, do not fully submerge the connector long-term without proper sealing.
