Portable dynamic valve distribution system

System name: portable dynamic valve distribution system

Ii. System model: gds-p2

Three, use

Portable dynamic valve distribution system is a product specially designed and customized for third-party inspection organizations, which is convenient for on-site calibration and testing of gas equipment.

Iv. System composition

Portable dynamic gas distribution system (standard with two components, can be extended to three components)

◇ 7-inch LCD LCD touch screen

Standard with gas output handle probe rod (retractable) and chassis strap

Standard with built-in air pump

Built-in dc rechargeable lithium battery (charge for 6 hours, can continue to run for more than 12 hours)

According to the need to customize the flameproof type, in order to be used in hazardous sites.

Five, the overview

Portable dynamic distribution system is based on two components on the technology of dynamic distribution system, for the third party inspection agencies developed in the field use demand, the difference in the two components of dynamic distribution system is the system will be placed in a distribution system as a whole with straps hard small portable box, the built-in efficient lithium ion rechargeable batteries, can bring their own air pump to provide clean air source, in this way, we only need to carry a small bottle (AL2) standard gas can, do not need to carry a dilute gas source is more easy to carry, database system at the gases, gas up to 57 types, basic covers the gas of the commonly used,Use the computer directly through the selection.The maximum flow rate of the mixed gas is ≈4000mL/min.

Vi. Technical parameters

1. Distribution channel of gas mass flow controller: 2 channels

Path A (diluted gas): 0 ~ 3000mL/min

Route B (sample gas) : 0 ~ 1000mL/min

2. Accuracy: ≤±1%FS

3. Response time: 1...2 seconds

4. Repeatability: ±0.2% Rd

5. Range ratio: 1:50 (numerical mode: 1:187.5)

6. Leakage rate: tested <2 x 10-9 mbar l/s He

7. Power supply: +15...24 VDC @ 320 ma

8. Operating temperature: -10...70 ℃

9. Output: 4...20 ma, and RS - 232

10. Gas path: the gas path of the whole system adopts the anti-corrosion and anti-adsorption 316L stainless steel pipe or ptfe pipe with internal surface polishing treatment to reduce the corrosion of corrosive gas to the equipment and the concentration attenuation in the process of preparing easy to absorb trace gas.

System operation

1) the valve distribution system is operated by hd TFT touch screen, which is sensitive and easy to operate.

2) operation interface: there are two modes of valve distribution on the operation interface, one is flow mode and the other is concentration mode.We can choose the mode according to our own needs, and we can also set the sequence of many kinds of valve concentration in advance to realize programmed automatic valve distribution.

Eight, standard configuration

Gds-p2 main engine, handle probe rod (retractable, about 3 meters) and chassis strap, ptfe tube, Chinese specification, qualification certificate, warranty card, etc.
