2015年11月16日——Queensgate公司NPC-D-5200是一款用于與該公司非常先進(jìn)的閉環(huán)壓電執(zhí)行器和工作臺(tái)配合使用的數(shù)字控制器,；它在動(dòng)態(tài)性能和精度上提供了新基準(zhǔn),。Queensgate 率先在閉環(huán)中使用電容式傳感器來(lái)提供精確的位置反饋；NPC-D-520集成了精確的電容測(cè)量電路,，并以120,000次/秒的速度更新工作臺(tái)位置,，因此提供了高速高位置精度。它能夠滿足許多高要求的校準(zhǔn)和計(jì)量應(yīng)用,。通過(guò)采用專利低噪聲技術(shù),，工作臺(tái)位置噪聲得到了降低，因此在大多數(shù)實(shí)現(xiàn)中它只有幾十pm,。 

       NPC-D-5200控制器具有緊湊（268mm×194mm×70mm）,、輕量（1.7kg）的結(jié)構(gòu)。它集成了串行（RS232）,、USB2.0和以太網(wǎng)接口,，因此連接選擇不受限制，并且系統(tǒng)靈活性得到了最大化,。該器件具有覆蓋10℃至40℃的工作溫度范圍,。
