Rotating support for surface thermometer

Abstract

The invention discloses a surface thermometer rotating support which comprises a support body, a rotating disc with a notch and a sliding sleeve, and adjustable supporting legs are arranged at the four ends of the support body respectively. The support body is provided with a quincunx-shaped hollowed-out part, the quincunx-shaped hollowed-out part comprises a rotary disc hole position penetrating through the support body, at least three half-runway-shaped sliding sleeve hole positions are formed in the radial direction of the rotary disc hole position, sliding grooves are formed in the inner walls of the sliding sleeve hole positions, and three stages of steps are arranged between every two adjacent sliding sleeve hole positions and along the outer edge of the rotary disc hole position. Pressing blocks are arranged on at least two second-stage steps, the pressing blocks and the lowest-stage step form a limiting groove for the rotating disc to rotate along the hole site of the rotating disc, and the rotating disc rotates on the horizontal plane along the limiting groove; a sliding block is arranged on the side wall of the sliding sleeve, the sliding sleeve is in sliding connection with the sliding groove through the sliding block, the sliding sleeve can be pushed to slide to the notch of the rotary disc from the sliding sleeve hole position, and the surface thermometer probe in the sliding sleeve is made to be perpendicularly attached to the center of the heat stage plane of the surface temperature calibration source. The preheating device is used for preheating a plurality of surface thermometers before calibration.

Description

technical field [0001] The invention relates to a surface thermometer rotating bracket. Background technique [0002] A surface thermometer is an instrument specially used to accurately measure the surface temperature of an object, and it is a classification of thermometers. [0003] The surface thermometer consists of a surface temperature sensor and a display instrument. The surface temperature sensor is a key component of the surface thermometer, and its performance directly determines the performance of the surface thermometer. Usually, the surface temperature sensor is a dedicated temperature sensor, which can be a thermocouple or a thermal resistor. In order to avoid measurement errors caused by the heat conduction of the sensor's own shape and interference with the original temperature field, it is required that the surface temperature sensor must have a sheet shape with an extremely thin thickness. The display instrument can be a commonly used thermocouple or ther...

Problems solved by technology

Depending on the type of probe, the equilibration time is several minutes to more than ten minutes. It takes a long time to calibrate multiple surface thermometers at a time, and it is difficult to improve work efficiency.
