InficonVGC502

A Python 3 module to communicate with an INFICONVGC502 controller over TCP. It supports reading pressure values from one or more gauges.

Currently Supported Models

• VGC501, VGC502

Features

• Connect to VGC controller
• Read out the pressure

🛠️ Requirements

• Python 3.7+
• Install base class from https://github.com/COO-Utilities/hardware_device_base

Installation

pip install .

🧪 Running from a Python Terminal

You can also use the INFICON module interactively from a Python terminal or script:

from inficonvgc502 import InficonVGC502

vgc502 = InficonVGC502()
vgc502.initialize()
pressure = vgc502.get_atomic_value("pressure1") # must have gauge number
print(f"Pressure: {pressure} Torr")

Testing

Unit tests are in the tests/ directory.

To run all tests from the projecgt root:

python -m pytest
