The invention provides an electromagnetic ultrasonic sensor with a function of temperature monitoring, and a detection system. The ultrasonic sensor comprises a housing and an ultrasonic detection module disposed in the housing. The ultrasonic sensor also comprises a temperature detection module, and the temperature detection module comprises a first temperature detector and a temperature monitoring unit, wherein the first temperature detector is disposed in the housing. The temperature monitoring unit is electrically connected with the first temperature detector, and is used for receiving a first temperature value detected by the first temperature detector, and comparing the first temperature value with a first preset value. When the first temperature value is greater than the first preset value, the temperature monitoring unit gives an early-warning signal. In addition, the ultrasonic sensor is separated from a tested workpiece, thereby guaranteeing that the temperature of the ultrasonic detection module is kept in a safety temperature range, and guaranteeing the application performance and service life of the ultrasonic sensor.
Description
technical field [0001] The invention relates to the detection field, in particular to an electromagnetic ultrasonic sensor and a detection system with a temperature monitoring function. Background technique [0002] Electromagnetic ultrasonic is an important means of on-line detection of high temperature equipment, among which high temperature electromagnetic ultrasonic sensor is the core part to realize high temperature detection. High-temperature electromagnetic ultrasonic sensors are divided into active cooling type and non-active cooling type according to their cooling methods. Active cooling type sensors require a special cooling system with complex structure and large volume. The sensor has been widely used in engineering high-temperature detection because it does not need an attached cooling device and has the characteristics of simple structure, small size, and portability. [0003] Since there is no active cooling measure, in order to protect the sensor components ...
