▼Product Introduction
DFS 0416-AT pressure electronic scanning valve is developed for small-range, high-precision application scenarios. It is a 16-channel fully independent high-performance pressure acquisition module for multiple measurements of dry, non-corrosive gases. The scanning valve integrates 16 silicon piezoresistive pressure sensors and gas path switching valves, has a common reference end, and the reference end can be externally connected. It has functions such as pressure testing, pressure calibration, and pipeline purging. Its interface and control commands are fully compatible with PSI 9116, and can be mixed with PSI 9116. It supports Labview software development functions.
Each channel of the DFS 0416-AT pressure electronic scanning valve uses a separate gas pressure sensor to ensure measurement accuracy through internal zero calibration, full-scale calibration or custom multi-point calibration and online calibration functions, and supports self-test and factory recovery.
Accessories include: power adapter (220V AC input, 24V DC output), transmission cable (customizable length) and dedicated data switch (power supply and signal transmission to the computer via one network cable, supporting up to 12 sets of simultaneous connections). Users can flexibly configure the matching host computer interface according to specific usage scenarios.
