Description

Sensor device Technical Field The utility model relates to the technical field of sensors, in particular to a sensor device. Background The temperature sensor is a device capable of sensing temperature change and converting the temperature change into a usable output signal, is a core component of the temperature measuring instrument, can be divided into two main types of contact type and non-contact type according to different temperature measuring modes, and mainly can be divided into two types of thermal resistance type and thermocouple type according to the characteristics of materials and electronic elements adopted by the sensor, and has various types and wide application, and plays a key role in various temperature monitoring and control systems. However, in the long-time storage process of the existing temperature sensor, the induction needle is usually directly exposed to the external environment and is easy to erode by environmental factors such as dust and moisture, meanwhile, in the storage and taking processes, the induction needle is also extremely easy to damage due to collision, so that the induction precision and the measurement reliability of the induction needle in use are affected, the service life of the sensor is shortened, in addition, the wires of the existing sensor are generally longer, the winding and messy conditions are easy to occur in the storage process, the space is occupied, and the management is inconvenient. Disclosure of utility model The utility model aims to solve the defects in the background art, provides a sensor device, and aims to solve the problems, effectively protect an induction needle through the arrangement of a protection component, prevent corrosion of external factors and damage caused by physical collision, wind up a temperature sensor wire through the arrangement of a storage component, and store redundant wires in the use process, so that the problem that the working environment is disordered due to overlong wires is avoided.
