Abstract
A reconfigurable pressure transducer assembly having an input tube filter assembly is provided. The resonant frequency and dampening characteristics associate with the pressure transducer assembly may be configured by the input tube filter assembly. The input tube filter assembly includes one or more inserts disposed in an input tube channel, the one or more inserts including one or more bores of selectable dimensions and extending therethrough from a first end to a second end. The one or more inserts define an effective input tube bore, and the input tube filter assembly is tunable by selection of the selectable dimensions of the one or more inserts.
Claims20
A tunable pressure transducer, comprising:
- a housing that includes:
- an input tube channel;
- and
- a cavity channel in communication with the input tube channel;
- an input tube filter assembly disposed in the input tube channel and in communication with the cavity, the input tube filter assembly comprising:
- one or more inserts disposed in the input tube channel, the one or more inserts comprising one or more bores of selectable dimensions and extending therethrough from a first end to a second end, wherein the one or more inserts define an effective input tube bore, and wherein the input tube filter assembly is tunable by selection of the selectable dimensions of the one or more inserts.
A kit, comprising:
- an insert holder defining a holder cavity having an inner diameter and a length;
- one or more grouped sets of one or more inserts configured for selection and insertion into the holder cavity, each insert comprising:
- an outer diameter corresponding to the inner diameter of the holder cavity and
- one or more bores of selectable dimensions, the one or more bores extending therethrough from a first end to a second end of each of the one or more inserts;
- the one or more grouped sets of the one or more inserts are further characterized by a number count and a corresponding effective length equal to the sum of the lengths of the one or more inserts such that the effective length corresponds to the insert holder cavity length;
- wherein the one or more grouped sets of the one or more inserts are configured to define an effective input tube bore of a tunable pressure transducer assembly, wherein the effective input tube bore is tunable by selection and insertion of the one or more grouped sets of one or more inserts into the insert holder.
A method, comprising:
- providing a housing having an input tube channel in communication with a cavity channel;
- selecting one or more inserts, each of the one or more inserts comprising one or more bores of selectable dimensions and extending therethrough from a first end to a second end;
- inserting the one or more selected inserts into the input tube channel to form an input tube bore;
- providing a header;
- mounting a sensing element to a header;
- and
- securing the header to a portion of the housing to define a cavity in communication with the cavity channel, the sensing element, and the input tube bore.
