Electro-Pneumatic Pressure Regulators and Valves FUKUDA

FUKUDA electro-pneumatic regulators deliver precise pressure control for automated test circuits. Fast-acting pneumatic valves and calibration leak masters ensure testing stability across repetitive cycles. Components withstand pressure shocks under continuous plant operation.

Electro-pneumatic pressure regulators with 4–20 mA or digital bus control
Precision calibration master leaks and reference orifices with inspection sheets
High-speed directional control pneumatic valves minimizing cycle actuation delays
Durable valve seat construction offering long service life in industrial air lines

Differential Pressure Measurement and Temperature Compensation Architecture

FUKUDA FLA series differential pressure air leak testers deliver high-precision seal integrity testing for automotive powertrains and die-cast housings.

The system pressurizes both the test workpiece and an internal reference master simultaneously, measuring minute pressure drops with an ultra-sensitive transducer. Proprietary digital temperature compensation algorithms neutralize thermal drift generated during upstream machining processes.

This ensures dependable measurement repeatability across high-volume automated production environments.

EV Battery Enclosure and Powertrain Airtightness Inspection Systems

Compact FUKUDA FLZ-0630 series air leak testers are purpose-built for electric vehicle battery packs, cooling plates, and motor drive enclosures. Enlarged internal pneumatic ports facilitate rapid pressurization of large test volumes without sacrificing sensitivity to micro-leaks.

Dual-mode testing executes sequential positive pressure and vacuum checks within a single automated clamp cycle. The intuitive color touch screen plots real-time decay curves and transfers comprehensive quality records to factory manufacturing execution systems.

Laminar Flow Testing with FMZ Series for Continuous Passage Evaluation

FUKUDA FMZ-1063 and FM-8010 series flow testers evaluate continuous volumetric airflow through orifices, automotive manifolds, and medical catheters.

Unlike static pressure decay instruments, these units continuously monitor dynamic flow rates utilizing precision laminar flow elements paired with differential sensors.

The methodology instantaneously reveals internal restrictions, casting burrs, and foreign particle blockages in critical fluid paths. Measurement ranges span from small fractions of a milliliter to hundreds of liters per minute.

HDZ-0201 Hydrogen Tracer Gas Sniffing for Hermetic Electronic Components

High-sensitivity FUKUDA HDZ-0201 leak detectors utilize an industrial non-flammable forming gas mixture of 5% hydrogen and 95% nitrogen. The system detects micro-fissures down to 0.1 ppm concentration resolution in local vacuum chambers and handheld sniffing applications.

It offers a cost-effective, dependable alternative to helium mass spectrometry for sealed sensors, quartz oscillators, and semiconductor packages. Rapid chamber desorbing ensures zero background contamination between consecutive testing cycles.
