Abstract
A sensor, and a sensor object combination, makes possible the collection of vibratory data from an object while reducing extraneous data and making easier the obtainment of the data. The sensor comprises an elastomeric housing which includes a concave cup portion, and pick-up devices for collecting vibration signals. The concave cup portion comprises a suction cup which makes possible vacuum attachment of the pickup device to the object being tested. The data signal may be amplified, analyzed, and ultimately the data may be analyzed by a computer.
Claims13
A sensor for measuring vibrations in an object comprising
- (a) a pickup means for collecting vibration data of an object by contact with said object and converting said data to an electrical signal, and
- (b) an elastomeric material in the form of a housing wherein at least a portion of said housing forms at least one suction cup and provides means for vacuum attachment to the object being measured and wherein said housing has a hub portion for holding a pickup portion of the sensor, said hub having smaller dimensions than said pickup portion for holding said pickup means with a vacuum tight seal.
An object/sensor combination which includes a sensor for measuring vibrations in an object comprising
- a) a pickup means for collecting vibration data of an object by contact with said object and converting said data to an electrical signal
- b) an elastomeric material attached to said pickup means which holds said pickup means and provides means for vacuum attachment to the object being measured
- and a high transmitting media covering the pickup portion of the sensor and providing indirect contact between the pickup means and the object and a vacuum enhancing material covering said high transmitting media to increase the vacuum seal between the elastomer housing of the sensor and the object.
