2）高精度
3）反應(yīng)快速
4）緊湊型結(jié)構(gòu)和數(shù)字通訊
Type Description
The mass flow controller (MFC) type 8713 is suited for regulating the mass flow of gases over a big flow range. The thermal MEMS sensor is located directly in the gas stream and therefore reaches very fast response times. A direct-acting proportional valve from Bürkert guarantees a high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC. Type 8713 can optionally be calibrated for two different gases; the user can switch between these two gases. The communication with master devices is fully digital, therefore no further analog/digital conversions are needed. The mass flow controller type 8713 fits for various applications, like e.g. burner controls, heat treatment, material coatings, bio reactors, fuel cell technology or test benches.
1）Nominal flow ranges from 0.010 lN/min to 80 lN/min
2）High accuracy and repeatability
3）Very fast settling times
4）Digital communication via RS485
5）Compact version
