Ultra Low Pressure Air Controller, MicroAir IV, with 0-10 volt input
for controlling by PLC or other device and for high speed switching for bump or taper tubing.
Application: Initially designed for bump and taper tubing, the MicroAir IV accepts a logic input to select one of two set points. A zero to 10 VDC analog input to provide any pressure from near zero to full scale instantaneously. For bump or taper tubing, the MicroAir IV allows for a pressure to be switched quickly or varied in a controlled way. It can be connected to your PLC or any controller with the 0-10 volt input. With an added output option you can have closed-loop control.
Operation: The MicroAir IV is connected to normal factory air. It regulates to the pressure set by a 0 to 10 volt input, or to one of the two manually set pressures by expelling surplus air. A precision voice-coil linear motor (no spring) with viscostatic damping ensures optimum speed and stability.
Operational Modes:
- Dual State mode – using logic signal to select which of two pressure set points is active. The Hi and Lo set points are adjusted with front panel knobs.
- Linear mode – A zero to 10 volt input controls pressure. The adjustable set points are ignored.
- Manual Setting– Set by turning the left side potentiometer only.
Performance: The MicroAir IV responds to a step of 50% of full scale in less than 0.1 second (typically 20 msec) and maintains an accurate pressure at flow rates between zero and a maximum SCFH depending on the full scale range.
