高壓液體自動控制器
7615采用了脈寬調制閥技術，的氣壓到液壓增壓器使自動高壓校準到275MPa成為現(xiàn)實,。7615系列是自動壽命/ 疲勞測試的理想選擇：
傳感器生產(chǎn)廠家,，如船用柴油機傳感器和變送器
高壓汽車傳感器，如剎車系統(tǒng)
節(jié)流閥體傳感器
需要使用高壓液壓進行測試,、計量的場合
多種控制模式
正?？刂颇Ｊ?/strong>
控制參數(shù)優(yōu)化,，實現(xiàn)小過沖,、快速達到控制壓力點,。測試結束后，壓力被釋放到儲液罐從而實現(xiàn)快速減壓,。如果活塞先于zui小壓力設定點到達行程末端,，會自動進行下一個循環(huán)。該時間與介質,、系統(tǒng)容積,、幾何尺寸、被測設備都有關系,。典型控制時間是50cc容積,，10%步進，達 到控制穩(wěn)定性時間是30秒,。
快速控制模式
7615非常適用于對時間和控制速度要求非常嚴格的場合,。此模式可以在50cc容積負載下，通常5秒內就可達到0.25%精度,。如果時間長一點,，7615可以達到0.01%控制穩(wěn)定性。
其它操作模式：
循環(huán)模式
用戶設定好需要循環(huán)測試的zui大壓 力,。7615系列控制zui大壓力,，在達到zui大值后所能達到的zui小壓力值是根據(jù)被測產(chǎn)品的容積而訂的。因此zui小壓力值無法定義,，(如果必須定義,，詳見掃描模式)。壓力值會在zui大和zui小值之間循環(huán)變化,，直到達到設定的循環(huán)次數(shù),。壓力變化速率和保持時間可以定義。
掃描模式
除了在掃描模式zui小壓力點需要定義外,，其他類似于循環(huán)模式,。
