  • IP address configuration tutorial

    IP address configuration tutorial An Alicat device with Ethernet-based protocols has an IP address to distinguish it from other devices on the network. This can be set either as a static address, or an address determined by a DHCP (Dynamic Host Configuration Protocol) server. The front panel accessibility for this feature makes it possible to […]

  • Control deadband tutorial

    Control deadband tutorial The dual valve PCD-Series maintains fast, precise closed system pressure control with minimal gas waste. This stable control is primarily due to a well-balanced PD2I algorithm. However, changing ambient conditions can still cause oscillation loops. Controller deadband creates a ± band of change around the chosen setpoint, minimizing oscillation loops in dual valve […]
