1 Introduction

The temperature measuring instrument with high speed 16 bit embedded microprocessor core. Using the automatic calibration circuit, using the measurement of the temperature of cold end temperature sensor precision, and can be a software correction. Using high precision AD conversion chip in data acquisition, the sampling period is 20ms, the frequency of space has very strong anti interference.

Measurement of the temperature measuring instrument can be applied to the solution temperature, aluminum, cast iron steel industry, also can measure the temperature of slag.

3 Technical parameters

4 Panel

The panel is provided with a three measurement indicator: preparation, measurement, end, and three key：K1、K2 and K3。

5 Indicator lights and alarm horn control output instructions

In the absence of measurement is not yet inserted thermocouple temperature measurement instrument, display the current time, the three lights are not bright, insert the thermocouple after the green light, the thermocouple is inserted into the molten steel after the yellow light, when measured after the success of the red light, at the same time the alarm output control.

After testing the test results show that 180 minutes 5 seconds, horn, trumpet for active DC12V output. Schematic wiring as shown below:

6 Set key and dial the specific operating instructions

There are three key K1, K2 and K3 in the thermometer on the front panel is used to set the date, time and operation parameters. The K1 key is used to select parameters to set (the specific item number shown in the table below), the K2 is used to select the set position, K3 is used to input a specific parameter value.
