Bently Nevada transducer systems are all manufactured to meet published performance specifications. They have a specified linear range, average scale factor (ASF) and incremental scale factor (ISF). Transducer systems have maximum deviation from straight line (DSL) and ISF tolerances, both at ambient temperatures and for extended temperatures. The 3300 XL Precision Micrometer can help verify whether the transducer system is working properly and within published specifications. A precision micrometer checks the transducer system. A probe mounting adapter holds the probe while a high precision 4140 target button is moved toward or away from the probe tip in specific increments. This target button simulates the position of the shaft. The output from the Proximitor® Sensor is recorded using a voltmeter. You can then verify the operating condition of the transducer system by comparing a newly generated probe curve using the 3300 XL Precision Micrometer with published specifications for that transducer system. You can also check and verify the proper operation of shaft position monitors using this micrometer. 3300 XL Shaft Micrometer The 3300 XL Shaft Micrometer is primarily used to check the output signal of a Proximitor Sensor when viewing the rotor shaft or a reciprocating compressor piston rod. A strap attaches to a mounting base, is wrapped around the target, and is tightened to hold the mounting base firmly in position. A spindle micrometer verifies the Proximitor Sensor output signal. A probe mounting adapter holds the probe in the mounting base, and the micrometer moves the probe toward and away from the target in calibrated increments. The output from the Proximitor Sensor is recorded using a voltmeter. When using the 3300 XL Shaft Micrometer to generate an output curve for programming a Rod Drop Monitor on a reciprocating compressor, use the buffered output signal on the front of the rod drop monitor rather than the output signal on the Proximitor Sensor. This is because the Rod Drop Monitor is programmed by the user based on the signal at the monitor. This signal will vary from the output signal on the Proximitor Sensor if you are using intrinsic safety barriers. The 3300 XL Shaft Micrometer also comes with a target holding base and a calibrated 4140 target button to verify that your Proximitor Transducer System is working properly.
