Key Features

The 200150-05-05 delivers 100 mV/g sensitivity for general purpose monitoring. The ±245 m/s² measurement range covers most machinery vibration levels. The frequency response from 10 to 1000 Hz captures common machine faults.

The ceramic shear sensing element provides excellent stability. The shear geometry rejects base strain and thermal transients. As a result, measurement accuracy remains consistent over time.

The 316L stainless steel housing resists corrosion. The hermetic sealing prevents moisture ingress. Consequently, the accelerometer survives harsh industrial environments. The IP equivalent protection allows operation in condensing humidity.

The multiple hazardous area approvals include CSA, ATEX, and IECEx. Therefore, this accelerometer suits installations in explosive atmospheres. The wide temperature range from -40°C to +105°C supports extreme conditions.

The mounting stud option (05) provides a 3/8-24 to 1/4-28 UNF adapter. The 1-3/8 inch hex plate stud simplifies installation. The recommended mounting torque is 2.7 to 6.8 N•m.

Installation Guidelines

Install the 200150-05-05 on a clean, flat mounting surface. Apply a thin layer of coupling grease for better signal transfer. Hand-tighten the accelerometer into the mounting stud. Then torque to 2.7 to 6.8 N•m (2 to 5 ft•lbf).

Use the 3/8-24 female mounting thread for direct attachment. The mounting stud option adapts 3/8-24 to 1/4-28 UNF threads. Ensure the mounting surface is free of paint, rust, and debris.

Connect the accelerometer to a compatible Bently Nevada monitor. Provide excitation voltage between 4.7 and 5.5 Vdc. Verify the output bias voltage is +2.5 ± 0.23 Vdc. Allow up to 300 ms settling time after power-up.

Do not exceed the axial shock limit of 49,050 m/s². Protect the cable from sharp bends and abrasion. Keep the connector clean and dry during installation.
