Description

Sensor testing device Technical Field The utility model relates to the technical field of sensors, in particular to a sensor testing device. Background The sensor is a detection device which can sense the measured information and convert the sensed information into an electric signal or other information output in a required form according to a certain rule so as to meet the requirements of information transmission, processing, storage, display, recording, control and the like. And a temperature sensor is one type of sensor, which is a sensor that senses temperature and converts it into a usable output signal. The temperature sensor is a core part of the temperature measuring instrument and has various varieties. The measuring method can be divided into two main types, namely contact type and non-contact type, and the measuring method can be divided into two types, namely thermal resistor and thermocouple according to the characteristics of sensor materials and electronic elements. At present, the temperature sensor needs to be tested before leaving a factory, when high-temperature testing is carried out, the temperature sensor is generally placed into testing equipment, and the existing testing equipment generally only can test a single temperature sensor at a time, so that the efficiency is low. Disclosure of utility model In order to improve the testing efficiency, the utility model provides a sensor testing device aiming at the problems in the prior art. The utility model provides a sensor testing device, which adopts the following technical scheme: The utility model provides a sensor testing arrangement, includes the box, be provided with the test chamber in the box, the top of test chamber is provided with the opening, be provided with the heating element in the test chamber, be provided with the apron on the opening, be provided with a plurality of through-holes on the apron, the through-hole intercommunication has the screw sleeve, is provided with the screw post on the sensor, the screw post of sensor with screw sleeve screw-thread fit, the detection end of sensor passes the through-hole with the screw sleeve extends to in the box. Preferably, the heating element is a plurality of electrothermal tubes, the electrothermal tubes are arranged in parallel, and the electrothermal tubes are positioned at the bottom of the test cavity. Preferably, the inner wall of the test cavity is provided with a convex edge in a surrounding mode, and four side edges of the cover plate are supported on the convex edge. Preferably, the four corners of the cover plate are respectively provided with a support rod, and when the cover plate is supported on the convex edge, the bottom ends of the support rods are abutted to the bottom of the inner wall of the test cavity. Preferably, a handle is arranged on the cover plate. Preferably, the outer side surfaces of the box body and the cover plate are provided with heat insulation layers.
