Calibration device of temperature sensor

Abstract

The invention discloses a calibration device of a temperature sensor. The calibration device comprises a housing. A water charging pipe is welded to the left side of the top of the housing. A support is fixedly installed on the inner bottom end of housing. A heating pipe is clamped in the top of the support. A perspective window with scales is arranged on the front face of the housing. A temperature dial is fixedly installed on the front end of the right side of the top of the housing. Double-metal thermometers which are in transmission connection with the temperature dial are arranged at the bottom of the temperature dial. A temperature sensor fixed seat is fixedly installed in the middle part of the top of the housing. A DSP control electric box is fixedly installed on the right side of the temperature sensor fixed seat on the top of the housing. The power supply input wire connection column of the heating pipe is electrically connected with the power supply output end of the DSP control electric box. According to the invention, the calibration device is simple and proper in structure and design, convenient to operate, safe, stable, low in manufacturing cost, rapid in temperature adjustment, long in service lifetime, widely applicable, and worthy of promotion and popularization, and heat is slowly dissipated.

Description

technical field [0001] The invention belongs to the technical field of grinding machines, and in particular relates to a temperature sensor calibration device. Background technique [0002] Temperature sensors are widely used in various industries. With the aging of components and equipment, the accuracy of temperature sensors will decrease. The occurrence of this phenomenon can affect the production quality of industries using temperature sensors. This requires regular calibration of the accuracy of the temperature sensor by means of a temperature sensor calibration device. However, most of the temperature sensor calibration devices in the prior art have complex structures, high manufacturing costs, and generally short service life, which is not conducive to widespread promotion and popularization. Contents of the invention [0003] The purpose of the present invention is to provide a temperature sensor calibration device to solve the problems raised in the background a...
