精密儀器是指用以產生、測量精密量的設備和裝廾置,包括對精密量的觀察、監視、測定、驗證、記錄、傳輸、變換、顯示、分析處理與控制。精密儀器是儀器儀表的一個重要分支。
 精密儀器種類繁多、結構各異。對于用于測量的精密儀器而言,.中勘測繪工程|||大理精密儀器銷售
,可將其結構分為基準、感受轉換、轉換放大傳輸、瞄準/讀數、數據處理、顯示記錄、驅動控制、機械結構等八大功能部件。但并不是說一臺精密儀器中必須包含上述八大功能部件,而是應根據儀器功能的要求有所選擇
1.機械技術
 儀器各部分的安裝固定,儀器測量精度、定位精度和運動精度的保證,由精密機械系統來實現和完成。精密儀器的測量控制對象也通常為機械結構的運動量。
 2.電子技術
 實現信號的轉換、傳輸、放大。研究對象包括:
 ①測量電路:實現信號的轉換。
 ②計算機控制:包括信號處理肀分析,以及在此基礎上的自動控制(發出控制指令)。
 ③伺服驅動:電子與機械部分的接口,按控制指令的要求控制被控對象實現預定的動作。
 3.光學技術
