Description

Technical Field

[0001] The utility model belongs to the technical field of temperature sensors, and in particular relates to a temperature sensor. Background Art

[0002] A temperature sensor is a sensitive component that can sense temperature and convert it into a usable output signal. It is an indispensable part of modern measurement and control systems. With the continuous advancement of science and technology and the increasing popularity of industrial automation, temperature sensors are being used more and more widely in various fields. The requirements for their accuracy, stability, and reliability are also becoming higher and higher. Temperature sensors generally need to be fixed to objects with a bracket.

[0003] For example, a Chinese patent with publication number CN217586091U discloses a clamp-type temperature sensor, including: a temperature sensor, a clamp kit, the clamp kit including a clamp ring, a stud, a first locking nut and a second locking nut, the temperature sensor is installed on the clamp ring, the clamp ring has two clamp arms, both clamp arms are provided with a convex portion, both convex portions are provided with a through hole, the stud is located in the two through holes, one end of the stud is exposed outside one of the through holes, and the other end of the stud is exposed outside the other through hole, the first locking nut is screwed to one end of the stud, and the second locking nut is screwed to the other end of the stud; an anti-slip kit, the anti-slip kit including a first anti-slip pad and a second anti-slip pad, the first anti-slip pad is installed on one of the clamp arms, and the second anti-slip pad is installed on the other clamp arm.

[0004] The above-mentioned clamp kit and anti-slip kit greatly improve the installation stability of the temperature sensor, but the clamp type has some defects that need to be improved. The clamp type fixation is mainly suitable for fixing tubular objects, which to a certain extent limits its wide application. Since the adaptability of the clamp is relatively limited, it can often only adapt to tubular objects within a specific size range, which undoubtedly increases the limitations and inconvenience of use. In addition, the temperature sensor is installed on the clamp and its probe is exposed to the outside, which is easy to be damaged and easily adhered to dust, thereby reducing the sensitivity and measurement accuracy of the temperature sensor.
