Embodiment Construction

[0022] The following description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different figures identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the invention is defined by the appended claims. For the sake of brevity, the following embodiments are discussed with respect to the terminology and structure of a machine having an axis of rotation. However, the embodiments to be discussed subsequently are not limited to these systems, but are applicable to other systems requiring proximity sensors.

[0023] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places thr...

Abstract

Method and gap analyzer device configured to determine a gap in a turbo-machine. The gap analyzer device includes a housing configured to receive a rechargeable battery; a voltage multiplier unit configured to increase a voltage of the rechargeable battery to a predetermined value; a voltage stabilization unit configured to stabilize the voltage having the predetermined value; an output port configured to output the voltage having the predetermined value to a probe; an input port configured to receive from the probe a signal indicative of the gap of the turbo-machine; a processor unit configured to determine a voltage associated with the signal; a display configured to display the determined voltage; a common port connected to the voltage stabilization unit, the voltage multiplier unit and the display; and a switch electrically connected between the processor unit and the battery for switching on and off the gap analyzer device.

Description

technical field [0001] Embodiments of the subject matter disclosed herein relate generally to methods and systems, and more specifically, to mechanisms and techniques for measuring gaps. Background technique [0002] A proximity sensor is a device capable of measuring the gap (distance) between the sensor and an object. Proximity sensors can be installed on various turbines in order to determine vibrations in the machine, for example. It is well known that turbomachines such as compressors, expanders, gas turbines, pumps etc. have a shaft which rotates relative to the casing. Due to various factors, the rotation of the shaft is not perfect and torsional vibrations may occur in the shaft. Torsional vibration can damage the shaft or shorten the life of the shaft when not controlled. [0003] Therefore, operators of turbines take care to monitor for possible torsional vibrations in the shaft. One way to monitor these vibrations is to place a proximity sensor close to the sh...
