美國PROPOTION-AIR公司成立于1985年,法人總統(tǒng)丹尼爾五庫克利用對銷售及市場推廣前景的*發(fā)明一種電子式空氣壓力調(diào)節(jié)器。這氣壓裝置設(shè)計以接受各種電子模擬和數(shù)字信號,以控制氣動壓力與準(zhǔn)確性,而否定的影響,振動,安裝位置或環(huán)境方面的關(guān)注。
Proportion-Air制造完成閉環(huán)質(zhì)量電子流量控制閥門,快速響應(yīng)和控制空氣流量的能力從2 SCFH 250 SCFM。
我們所有的電子積木的空氣流量控制閥是f系列質(zhì)量流量傳感器。 f系列使用高速壓差技術(shù)產(chǎn)生一個電信號與空氣的質(zhì)量流量成正比——或者任何你想控制的氣。
這個高速流信號能夠使用各種Proportion-Air直接質(zhì)量流量控制閥關(guān)閉循環(huán)氣流。 根據(jù)你需要的空氣流量,f系列流傳感器匹配適當(dāng)?shù)牧髁靠刂崎y,然后專門校準(zhǔn)你的精確的流量范圍。
每個電子流量控制閥不斷地將你的命令信號,傳感器信號的f系列流量傳感器。 然后控制閥打開或關(guān)閉(幾乎瞬間)保持吩咐流量。 *QB1TFEE150比例閥
Proportion-Air manufactures two types of flow control valves; closed loop mass flow control valves and open loop variable orifice flow control valves. The F-series mass flow transducer is the heart of the closed loop models. The F-series calculates flow based on differential pressure which results in very fast flow measurements. This flow can be connected to Proportion-Air’s pneumatic control valves as a feedback loop for closed loop control. The FCV (Flow Control Valve) is a variable orifice angle seat design. The FCV closes the loop around an internal valve position with an integral LVDT. The position of the valve directly correlates to valve flow capacity (Cv) based on careful design of the parabolic valve plug geometry.
Our Complete Line of Electronic Flow Control Valves
electronic flow controlProportion-Air manufactures complete closed-loop mass electronic flow control valves that have quick response and the ability to control air flow rates from 2 SCFH to 250 SCFM.
The building block for all of our electronic air flow control valves is the F-series mass flow transducer. The F-series uses high speed differential pressure technology to produce an electrical signal proportional to the mass flow of air – or, whatever gas you want to control.
This high speed flow signal is able to be used by a wide variety of Proportion-Air mass flow control valves to close the loop directly around air flow. Based on your required air flow rate, the F-series flow transducer is matched to the appropriate flow control valve and then calibrated specifically to your exact flow range.
Each electronic flow control valve constantly compares your command signal to the transducer signal of the F-Series flow transducer. The control valve then opens or closes (almost instantaneously) to maintain the commanded flow rate.
