ZL***1 suction resistance measuring equipment
Patent NO. ZL***********7.3    ZL***********2.1   ZL***********3.4   ZL***********1.0
ZL***********5.9
This equipment obtains the national patent for invention and 3 patents for utility models.
 

1. Collect Setra company high precision differential pressure transmitter and C.F.O. to control vacuum suction flow in order to detect voltage drop value of every sample
2. Automatically calibration function
3. Execute GBT / *********2 standard
4. Adopts rotary cylinder and double acting cylinder with ‘ v ’ structure at the bottom to seal. Seal ring is made of durable silicone.
5. Adopts Cambridge filter disc to filter air and protect CFO and pipe from polluting, thus prolong life-span of CFO. Filter disc is installed outside of equipment, which makes it convenient to replace.
6. Compared with the same type instruments at home and international, the main negative pressure pipe is shorter and thicker( pipe diameter larger). This kind of pipe effectively reduces the disturbance on the detection.
7. Differential pressure transmitter with high precision, low temperature and stable and reliable signal is imported the series of C**9 high precision transmitter of SETRA company, America.

1. Suction resistance measuring range: *****0mmWG
2. Resolution ratio: 1mmWG
3. Precision :±0.*5%FS(Full Scale)
4. Repeatability error: 2mmWG
5. Constant flow: (*7.5±0.2) ml/s
