概要HYDAC流量傳感器/德國賀德克流量傳感器

控溫穩(wěn)定度：優(yōu)于0.01℃/10min(油槽、水槽、
低溫恒溫槽);0.2℃/min(管式檢定爐)；
對于不同金屬來說，溫度每變化一度，
電阻值變化是不同的，
而電阻值又可以直接作為輸出信號。
Essential specifications are:
Nominal volume: up to 3,300 l,
Permitted operating pressure: up to 1,000 bar
Piston velocity: dependent on sealing
system, usually up to 5 m/s;
higher velocities possible,
Accumulator shell materials: carbon s
teel, stainless steel, aluminium.
The following advantages set HYDAC pisto
n accumulators apart:
minimal pressure differential
 between the fluid side and gas side,
large usable volumes,
variable installation position,

monitoring of the piston
 position possible using various systems,
particularly suitable for back-up configurations,
extreme flow rates,
no sudden discharge of gas when seals are worn.
雙金屬桿和金屬管傳感器
電阻共有兩種變化類型
正溫度系數(shù)
溫度升高 = 阻值增加
溫度降低 = 阻值減少
負溫度系數(shù)
金屬隨著溫度變化，其電阻值也發(fā)生變化。
