Alicat Scientific PCS-30PSIA-D-X Pressure Controller

Alicat Scientific PCS-30PSIA-D-X Pressure Controller is a compact digital controller in the PCS-Series designed to precisely regulate absolute pressure from 0 to 30 PSIA in flowing-gas applications. It delivers ±0.125% of full-scale accuracy and ±0.08% of full-scale repeatability, with a measurement and control range from 0.01 to 100% of full scale (up to a 10,000:1 turndown). The unit is compatible with all non‑corrosive gases and liquids within its wetted materials (consult specific material data for exact gas compatibility), and its compact form factor measures about 3.8 in tall × 3.6 in wide × 1.1 in deep with 1/8 in NPT female ports and mounting holes for secure installation. An on-device display provides setpoint and measured pressure on either a monochrome LCD or color TFT touch panel, so operators can monitor and adjust settings without a separate instrument. For connectivity, it uses RS-232 serial and Modbus RTU by default, with options for RS-485, Modbus TCP/IP, and additional industrial interfaces depending on configuration. Designed for use in lab benches, calibration rigs, and test setups, the PCS-30PSIA-D-X delivers reliable, repeatable pressure control in the 0–30 PSIA range using Alicat’s control algorithms and fast response characteristics.
