Abstract: [Object] To provide a method of manufacturing a low heat-resistant sensor that has high chemical resistance, excellent drip-proof properties, and excellent dust-proof properties.

Abstract: A low heat-resistant sensor that has high chemical resistance, excellent drip-proof properties, and excellent dust-proof properties is provided. The low heat-resistant sensor includes a sensor body that includes a sensor unit that is disposed in a housing and a cable that is electrically connected to the sensor unit of the sensor body. The housing of the sensor body is composed of fluorine resin, the cable is covered by a tube composed of fluorine resin, a portion at which the housing and the tube are connected to each other is thermally bonded, and the housing and the tube are integrally formed.

Abstract: A vibration analysis system includes: a signal input portion that receives an input of a vibration signal detected by a sensor; an intensity calculation portion that calculates a plurality of signal intensities corresponding to a plurality of frequency bands by analyzing the vibration signal; a first distance calculation portion that calculates a first Mahalanobis distance of a first signal space configured of the plurality of signal intensities with respect to a first unit space; a gravity center calculation portion that calculates two-dimensional gravity center data indicating gravity center positions of the plurality of signal intensities; a second distance calculation portion that calculates a second Mahalanobis distance of a second signal space configured of the gravity center data with respect to a second unit space; and an abnormality prediction portion that predicts an abnormality generation period of the object based on the first Mahalanobis distance and the second Mahalanobis distance.
