Sensor for acquiring rotating speed, temperature and vibration signals and manufacturing method

Abstract

The invention provides a rotating speed, temperature and vibration signal acquisition sensor and a manufacturing method, and belongs to the technical field of sensors. The sensor comprises a shell; a circuit board which is installed in the shell through a fastener, wherein a Hall element, a thermistor and an acceleration chip are welded to the circuit board, the Hall element corresponds to the speed measuring gear in position, the thermistor corresponds to the bearing in position, and the acceleration chip corresponds to the position of the bearing. According to the invention, the corresponding detection elements for detecting the rotating speed, the temperature and the vibration signal parameters are integrated on the same circuit board, and the circuit board is installed in the shell to form a single sensor, so that the size of the whole sensor is reduced on the basis of meeting the detection of the three parameters, and the miniaturization of the sensor design is realized; therefore, reasonable wiring and installation of the sensor in the bearing box with limited space can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of sensors, and relates to a sensor, in particular to a sensor and a manufacturing method for collecting rotational speed, temperature and vibration signals. Background technique [0002] In the prior art, dynamic real-time monitoring of speed signals, temperature signals and vibration signals is required for rotating shafting, especially for high-speed and heavy-duty bearings, which is crucial to the safe operation of equipment. Through the analysis of monitoring data, it can be realized Preventive maintenance of equipment, and early warning information to prevent operational accidents. [0003] The existing detection of the speed signal, temperature signal, and vibration signal of the bearing is basically detected by sensors, and most of the existing sensors are in the form of a single function, or only a combination of two functions, such as the temperature vibration sensor, must have both The detection ...

Problems solved by technology

[0003] The existing detection of the speed signal, temperature signal, and vibration signal of the bearing is basically detected by sensors, and most of the existing sensors are in the form of a single function, or only a combination of two functions, such as the temperature vibration sensor, must have both The detection of these three physical quantities requires at least two sensors. It is difficult to arrange the bearing box with limited space and the wiring is complicated.
