How MicroPC Pressure Controllers Work

The MicroPC uses high-precision electronic sensors and electronically controlled proportional valves to maintain the desired pressure setpoint:

  1. Pressure Sensing: Ceramic-based, low-outgassing sensors continuously monitor system pressure with ±0.08% FS repeatability.
  2. Valve Control: Electronically actuated valves make fine adjustments to maintain stability, even under fluctuating conditions.
  3. Feedback Loop: Temperature compensation (0–85°C) ensures that readings remain accurate, while dual-range capabilities provide precision at both low and high pressures.

Pro Tip: Matching the MicroPC to your system’s pressure vessel size and valve capacity guarantees optimal response times and performance. Smaller systems respond faster, while larger volumes stabilize efficiently.

Unlike traditional mechanical regulators, the MicroPC offers repeatable, digitally compatible pressure control, ensuring your system maintains consistent results across multiple cycles and setups.

What Sets the MicroPC Apart in Pressure Control

  • Compact, Space-Saving Design: At just 2.04” × 1.50” × 2.11” and 7.9 oz, it integrates easily into lab or industrial systems.
  • High Precision & Repeatability: ±0.08% FS repeatability and ±0.5–1.0% FS linearity error for consistent results.
  • Flexible Signal Options: Analog and digital outputs including 0–5 VDC, 0–10 VDC, 1–5 VDC, 4–20 mA, and RS-232.
  • Robust Construction: Nickel-plated aluminum manifolds, stainless steel valve components, and fluorocarbon (Viton®) O-rings ensure durability and long-term reliability.
  • Environmental Stability: Temperature-compensated for operation up to 85°C, humidity 5–95% RH, and storage from -40–70°C.
  • Minimal Leakage: Internal 10⁻⁵ @ 1, 30, 100 psi (He) and external 2 × 10⁻⁶ sccm (He).

The MicroPC turns technical specifications into tangible performance advantages, helping engineers maintain precise pressure in critical processes without compromise.
