The Bently Nevada 24765-02-01 is a DC casing expansion sensor primarily used to monitor the expansion or contraction of large rotating machinery such as steam turbines and gas turbines due to heat. Casing expansion is a key measurement in turbine monitoring instruments (TSI). Casing expansion refers to the thermal expansion of the turbine casing during startup and online operation.
The 24765-02-01 continuously measures the axial thermal expansion or contraction of the machine casing relative to its fixed foundation (ground), used to determine whether the rates of thermal expansion of the casing and rotor are similar. By monitoring this temperature difference, friction between rotating and stationary components can be prevented due to uneven or obstructed expansion. Before starting large rotating machinery, data from the casing expansion sensor can be used to shorten the start-up time of gas turbines using precise expansion feedback, thereby significantly reducing component damage caused by thermal stress. Additionally, the 24765-02-01 sensor provides position information for the sliding feet on the housing. When used in conjunction with a dual-housing expansion sensor configuration and a 3300 or 3500 monitor, it can alert the system if the sliding feet on the housing are obstructed or stuck, thus preventing housing deformation and machine damage.
Working principle of the housing expansion sensor: The housing expansion sensor assembly consists of a linear variable differential transformer (LVDT) housed within a weatherproof protective enclosure. This housing expansion sensor system utilizes the LVDT to measure the thermal expansion of the machine housing. A rod connected to the machine is linked to the LVDT. When the machine housing expands, the rod moves within the LVDT, thereby altering the signal inside. The sensor electronically modulates this signal and outputs it to a display for display and alarm functions. |
