Description

Technical Field

[0001] This utility model relates to the technical field of furnace temperature testers, and in particular to a furnace temperature tester for casting. Background Technology

[0002] A furnace temperature tester is a device specifically designed to measure and record temperature changes inside a furnace. It is widely used in industrial production, especially in fields involving heat treatment and firing processes. The furnace temperature tester primarily senses temperature changes inside the furnace through temperature sensors. Thermocouples convert temperature signals into electrical signals. The internal circuitry of the instrument amplifies and processes these electrical signals, ultimately displaying the temperature value in digital or graphical form. Furthermore, the tester records temperature data at set time intervals for subsequent analysis. Because it needs to operate in a high-temperature environment, the furnace temperature tester's casing and sensors are typically made of high-temperature and corrosion-resistant materials to ensure its stability and reliability in harsh environments. To meet process control requirements, furnace temperature testers usually have high measurement accuracy, capable of accurately measuring minute temperature changes.

[0003] Currently available furnace temperature testers for casting mainly consist of a casing and protective device, a temperature sensor, and a display and operation unit. In casting production, metal raw materials need to be placed in a furnace for melting. The furnace temperature tester can monitor the temperature changes inside the furnace in real time to ensure that the metal raw materials can be fully melted at the appropriate temperature, avoiding metal oxidation and burn-off due to excessive temperature. However, the casting workshop environment is harsh, with high temperature, dust, and vibration factors, which can affect the normal operation of the instrument. To solve the above problems, existing technologies only install the instrument in a location far away from high temperature and vibration sources and provide heat insulation and vibration reduction treatments, without improving the instrument's convenient storage. The furnace temperature tester is large and inconvenient to store, occupying a lot of space and affecting the spatial layout and equipment placement in the workshop, making the work area appear crowded and difficult to store. The temperature sensor, display screen, and communication interface are easily damaged by external factors, thus affecting the normal use and service life of the instrument and failing to meet the usage requirements. Utility Model Content
