1 簡介                                               

本測溫儀以高速16位嵌入式微處理器為核心。采用了自動校準電路，采用精密的溫度傳感器對冷端溫度進行測量，并可以進行軟件校正。在數(shù)據(jù)采集上采用高精度AD轉(zhuǎn)換芯片，采樣周期為20ms，對空間的工頻有很強的抗干擾性。

本測溫儀可適用于煉鋼、煉鋁、鑄鐵等行業(yè)中溶液溫度的測量，也可以測量爐渣溫度。

2 功能說明                                          

? DC12V有源喇叭輸出接口√

? RS485串行通訊接口（訂貨特殊說明）

? 微型打印機接口（訂貨特殊說明）

? RS232異步串行通訊接口（訂貨特殊說明）

? 帶隔離的BCD碼輸出接口（訂貨特殊說明）

? 模擬量4~20mA輸出接口（訂貨特殊說明）√

? 200條歷史測試數(shù)據(jù)存儲√

? 語音報數(shù)（訂貨特殊說明）

3 技術(shù)參數(shù)                                            

4 面板                                              

在面板上有三個測量指示燈：預(yù)備、測量、結(jié)束，和三個設(shè)定鍵：K1、K2和K3。

5 指示燈及報警喇叭控制輸出說明                       

在沒有測量即還沒有插熱電偶時，測溫儀顯示當前的時間，三個指示燈都不亮，插上熱電偶后綠燈亮，將熱電偶插入鋼水后黃燈亮，當測量成功后紅燈亮，同時報警控制輸出；如果測量失敗，則三個燈全亮。

5，喇叭為有源DC12V輸出。原理接線如下所示：（帶語音報數(shù)無此功能）

6 設(shè)定鍵及撥碼盤具體操作說明                        

在測溫儀前面板上有三個鍵K1、K2和K3，用于設(shè)定日期時間和運行參數(shù)。K1鍵用于選擇要設(shè)定的參數(shù)項（具體項的編號見下表），K2用于選擇要設(shè)定的位，K3用來輸入具體的參數(shù)值。
