structural principle
This instrument mainly consists of a host, a computer (provided by the laboratory), an interface, and a printer. The host and interface are the core of this instrument, while the remaining components are external components. Below is an introduction to the host and interface parts.
The host consists of a heating furnace, a probe, a temperature heating component, and a casing.
1. Furnace body:
The probe heating electric furnace is a well type electric furnace with temperature controlmanufactureThe range is from room temperature to 900 ℃,
2. Medium container:
Jietongde Entrepreneurship Quality can be stored in glass or stainless steel containers, with a standard capacity of 300ml for silver probes.
3. Probe:
The probe is a sensitive component for testing
The instrument is suitable for silver probes
4. Lifting mechanism:
The lifting mechanism can facilitate testing and ensure stable repetition of each action.
5. Software system
The software system of the instrument adopts a modular structure, with a menu dialogue user interface and a screen display in both Chinese and English, making it easy for users to operate and query management.
6. Data collection module:
This module is the core of this software, including the following parts.
(1) Parameter setting: Before the experiment, the parameters for the current experiment can be set (such as sample name, sample delivery unit, medium temperature, etc.).
(2) Heating monitoring: After the parameter settings are approved, the computer enters the heating monitoring stage. There is a heating curve and temperature display on the screen. When the temperature approaches the applicable temperature, the computer enters the insulation stage.
(3) Quenching data collection: After the holding time, the probe automatically descends and enters the medium (or can be manually entered into the medium quenching stage). At the same time, the computer collects data from the probe thermocouple at the selected rate.
(4) Data processing: After data collection, click the "Next" button with the mouse, and the computer will process the data and display the sampling curve, temperature change rate curve, special temperature seconds, maximum rate, time to drop to 600 ℃, 400 ℃, 300 ℃, 200 ℃, etc.
7. Drawing module:
Draw the sampled and processed curve of the test on the coordinate graph by Tongde Entrepreneurship.
8 File Management and Printing Module:
After the experiment is completed, you can choose to save the file and retrieve the test results over time. When connected to a printer, the test data can be printed. After saving the test results, a "Save Data" folder will be automatically generated, which can save an unlimited number of historical data.
