active pressure controller

Compact, Low Power Module Based on Piezo Actuator Technology

Parker’s Active Pressure Controller (APC) series is a family of compact, modular controllers. Based on piezeo actuator technology, the APC consumes minimal power (<40 mA at 12 VDC) while offering exceptional response time (<20 ms).

The onboard solid-state electronics provide outstanding accuracy (±0.2% FS typical) and high reliability. The APC control scheme enables "set and forget" operation for applications where stand-alone operation is desirable. Simply tune the APC's onboard pressure set point adjustment to the desired level and walk away. The onboard control loop will maintain pressure at the set-point indefinitely. If preferred, the APC can also be controlled through external control hardware.

Features & Benefits

• Piezo-based pressure controller offers high accuracy control with minimal power consumption — less than 40 mA draw at 12 VDC.
• Available in 5 standard pressure ranges to maintain precise control over a wide range of pressures.
• High-efficiency device produces minimal heat — no impact on sensitive flow measurements.
• Can be operated in stand-alone mode to avoid expense of an independent control system.
• Rapid response time (< 20 ms) gives high level of flow stability.
• Tailored to customer pressure/flow and mounting requirements.
• Available in voltage- and current-control modes — compatible with most common control schemes.

Multiple Product Configurations Available

Parker builds each APC around our customer's application requirements. Standard pressure ranges include 0-3.5 psid up to 0-145 psid; flow rates can be controlled in the range of 0-40 slpm of air. Two body styles are also available with 10-32 threaded ports featured on the Upright body and face sealing ports incorporated into the Manifold Mount body. Custom configurations are also possible. Please consult the factory for details.
