Bently Nevada 86517 Accelerometer Interface Module

Bently Nevada 86517 Accelerometer Interface Module

INTRODUCTION

The 86517 Accelerometer Interface Module is a component in accelerometer- based transducer systems commonly used for vibration monitoring of aeroderivative gas generators and gas turbines. The interface module is designed for use with the Bently Nevada 3300 series 3300/95 Filter Module/Vibration Monitor and can also be used with specially modified 3300 monitors such as the 3300/15 and 3300/25.

Extension Cable

The extension cable connects the accelerometer and the interface module and may consist of a single softline cable or two cables where the cable on the accelerometer side is a hardline, mineral-insulated cable rated for higher temperatures. The extension cables must be constructed with special low noise characteristics and resist high temperatures and corrosive environments. The low noise construction is a conductive treatment on the surface between the center conductors and the dielectric and between the dielectric and the inner shield. This treatment minimizes the charge induced between the surfaces by motion or vibration of the cable. This phenomenon is called triboelectric noise and can be particularly troublesome in charge amplifier systems. The total pole-to-pole capacitance of the accelerometer plus the distributed cable capacitance should not exceed 8300 picofarads. Cable drawings and schematics are in the appendix.

Accelerometer

For aeroderivative gas turbines, the accelerometers are typically provided with the engine either by the manufacturer or the packager and must be qualified by the engine manufacturer. Accelerometers of this type are typically constructed with a piezoelectric crystal isolated from the accelerometer case so that the accelerometer output is differential. Accelerometers used with the 86517 interface module must have a sensitivity of 50 picocoulombes per g or 100 picocoulombes per g, and the necessary connector.

Receiving, Inspecting, and Handling

Carefully remove the interface module, extension cable and accelerometer (if applicable) from their shipping containers and inspect them for shipping damage. If you remove the lid, be careful not to lose the two mounting screws located in the base of the interface module enclosure. If shipping damage is apparent, file a claim with the carrier, and submit a copy to Bently Nevada Corporation. Include part numbers and serial numbers on all correspondence. If no damage is apparent and the equipment is not going to be used immediately, return the equipment to the shipping containers, and reseal until ready for use. Store the equipment in an environment free from potentially damaging conditions such as high temperature, excessive humidity, or a corrosive atmosphere. See Section 6 for environmental specifications.
