The FAK-663 is a modular, high-accuracy micro-pressure/low-pressure pressure controller widely used in industrial and laboratory settings requiring automated pressure calibration, testing, and production. It combines built-in electric pump technology with fast-response control, making it particularly suitable for low-pressure and differential pressure applications.

The following are typical application cases based on its functional features:

1. Automated Pressure Instrument Calibration

Application Scenario: Periodic calibration of large numbers of pressure transmitters, pressure gauges, and pressure switches in metrology laboratories or factory maintenance shops.

Solution Case: Utilizing the FAK-663's automated pressure generation and control functions, combined with interchangeable FAK-151 pressure modules, it achieves full-range coverage from micro-differential pressure to low pressure. Using LabVIEW drivers or SCPI command sets, users can build automated calibration systems, significantly improving efficiency and reducing human error.

2. End-of-Line (EOL) Testing on Production Lines

Application Scenario: Rapid functional verification and performance testing on production lines for pressure sensors or medical devices (such as ventilators).

Solution Case: Thanks to the FAK-663's extremely fast response speed (20% pressure step completed within 10 seconds) and excellent stability (< 0.003% FS), it can quickly apply precise pressure to devices under test, meeting the stringent requirements for rhythm and accuracy in industrial automation testing.

3. Micro-Differential Pressure Sensor Performance Research

Application Scenario: High-stability testing of ultra-low range differential pressure sensors (e.g., ±2.5 mBar) in research laboratories.

Solution Case: The FAK-663's optimized low-pressure pump technology delivers typical control stability of 0.001% FS even at very small ranges. This is critical in the development of instruments for HVAC monitoring and cleanroom pressure gradient control.

4. Calibration in Contaminated Environments

Application Scenario: Calibration of industrial process pressure transmitters that may contain trace amounts of liquid or impurities.

Solution Case: The controller can be optionally equipped with a Contamination Prevention System (CPS). This system features automatic liquid drainage and integrated firmware that performs purging between cycles, protecting the internal precision valves from contaminants in the device under test and extending maintenance intervals.

5. Flexible Switching Between Multiple Ranges and Field/Laboratory Use

Application Scenario: Needing a single device to handle multiple different pressure range tasks.

Solution Case: The modular design allows control modules to be changed within 30 seconds. For example, in the same laboratory, a technician might need to calibrate a 1 bar industrial transmitter in the morning, and then switch to calibrating micro-differential pressure instruments in the afternoon by quickly changing the module—all without purchasing multiple separate mainframes.
