Inficon CDG020D 小型電容薄膜規(guī)技術(shù)說明
Inficon CDG020 有兩種精度:
CDG020D 精度在1% ,對應(yīng)對貨號為3CA3- 1% Accuracy
CDG020D 精度在0.5% ,對應(yīng)訂貨號為3CA4- 0.5% Accuracy
CDG020D 真空法蘭口,分別為:
DN16 KF
DN16 CF-R
4-VCR male (1/4 VCR male)
4-VCR female (1/4 VCR female)
8-VCR female (1/2 VCR female)
CDG020D 電氣接口有三種:FCC D-Sub 9-pin Binder M12, 8-pin, 三種接口示意圖如下
下圖為三個DN16KF 接口的CDG020 D,從左到右分別為FCC, D-Sub-9pin 及 M12-8pin
CDG020D D-Sub 9 pin 實拍圖如下:
對應(yīng)Inficon CDG020D 訂貨說明如下:
從上圖,我們可以看到訂購 Inficon英???/span>電容薄膜規(guī)CDG020D
1. 首先確定所需的精度(Acuurany),
允許測量精度在1%,選擇3CA3-
要求的測量精度在0.5% ,選擇3CA4-
2. 選擇所需要的量程(Full Scale)
如你要控制系統(tǒng)壓力精度在0.5% 壓力在3mbar, 你應(yīng)當(dāng)選擇Full Scale 在10mbar , 即 3CA4-96
如你要控制系統(tǒng)壓力精度在0.5% 壓力在950Torr , 你應(yīng)當(dāng)選擇Full Scale 在1000 Torr ,即3CA4-F5
注意,英福康電容薄膜規(guī)的測量范圍為Full Scale 下去兩個半量程,即選FS 為10mbar,測量范圍為10-0.05mbar
3. 選擇對應(yīng)真空法蘭接口:
1: DN16 ISO- KF
3: DN16CF-R
9: OD 1/2in Tube
C: 1/4in VCR male
D: 1/4 in VCR female
E : 1/2 in VCR female
K: 1.25 C-Seal surface mount
4. 選擇對應(yīng)電氣接口:
0: FCC, 8pin
1: D-Sub, 9 pin
A: Binder , M12 ,8-pin
如 CDG020D 0.5% 精度 100 Torr 滿量程 ,4-VCR female 真空接口, D-Sub 9 pin 電氣接口 , 對應(yīng)PN: 3CA4-C5D-0100
CDG020D 對應(yīng)機(jī)械圖如下:
CDG020D 對應(yīng)技術(shù)指標(biāo)如下:
上圖就是1/4 VCR female 法蘭口。
CDG020D 對應(yīng)管腳定義如下:
D-Sub 9 pin
FCC 8-pin
M12 , 8 pin

Zeroing the Gauge , 不同量程下,要求將真空抽到優(yōu)于如下值來較零:
The INFICON Porter CDG020D Capacitance Diaphragm Gauge is designed for stable long-time performance in industrial environments. The ceramic sensor provides excellent span stability over many years paired with outstanding zero stability.
An in-situ sensor architecture guarantees a short and long-term temperature stability.
Typical applications
? Pressure monitoring
? Vacuum coating, food packaging ? Vacuum cleaning, sterilization
? Analytical
? Vacuum ovens, puller
? Chemical vacuum processes
