Description

Technical Field

[0001] This utility model relates to the field of temperature sensor technology, and more specifically to a multi-point temperature sensor. Background Technology

[0002] A temperature sensor is a device that can sense temperature and convert it into a usable output signal.2 Its function is to sense the temperature changes of the measured object or environment in real time and convert the temperature information into measurable and processable signals such as electrical signals, so that people can perform temperature monitoring, control and regulation operations. It is widely used in many fields such as industry, agriculture, medicine, and home.

[0003] When temperature monitoring is required over a large area or in a complex environment, a single measuring point cannot accurately reflect the overall temperature situation. For example, in a large warehouse, a single temperature sensor cannot detect localized temperature anomalies in a timely manner, potentially leading to damage to goods due to localized overheating or undercooling. The monitoring range is limited, making it impossible to promptly detect temperature differences between different areas. Furthermore, in emergency situations, such as sudden equipment failure requiring rapid sensor installation, installation difficulties may cause delays. During routine maintenance or when sensor replacement is needed, installation difficulties also create inconvenience. This not only increases maintenance and replacement time costs but may also cause secondary damage to the equipment due to improper operation, affecting its normal operation. Utility Model Content

[0022] The measuring point assembly 3 includes an optical fiber end 301, an insulating sleeve 302, a positive electrode 303, a detection point 304, a negative dipole wire 305, a converter 306, and a connecting pipe 307. The optical fiber end 301 is fixedly inserted through the bottom of the outer casing 104. The insulating sleeve 302 is fixedly installed on the outer walls of the optical fiber end 301 and the positive electrode 303. One end of the positive electrode 303 is fixedly connected to the top of the optical fiber end 301, and the other end of the positive electrode 303 is fixedly installed inside the fixing plate 105. The detection points 304 are matrix-distributed and fixedly installed on the outer wall of the positive electrode 303. The negative dipole wires 305 are arranged in a matrix.

[0023] The working principle of this utility model:

[0024] The device is rotated by the hexagonal sleeve 101 so that the threaded sleeve 103 is threaded into the circuit where temperature activity is required. At this time, the optical fiber end 301 receives the current signal transmitted by the circuit, and the insulating sleeve 302 receives the current signal transmitted below. The current signal is transmitted inside the insulating sleeve 302, which can effectively avoid overheating or current loss during transmission. After the current passes through the detection point 304, the detection point 304 serves as the transmission medium. After the negative dipole wire 305 contacts the detection point 304, it transmits the RTD information to the converter 306. The converter 306 converts the RTD signal into a temperature signal and transmits this temperature signal to the control circuit board 202 through the connecting pipe 307. The operator can read the temperature signal by connecting the display device to the connection terminal 203. The ring-shaped distribution of the converter 306 is conducive to collecting and processing signals from multiple points, thereby reducing the deviation of the final temperature signal to a certain extent.
