This is a Python library to communicate with Thyracont's VSR53USB pressure gauge. It should also work with the VSR53DL model (over RS485) but I haven't tested it as I don't have access to one.

This library is a fork of this repository. All credits go to the original author.

The original library was designed for the RS485 protocol and does not work out of the box for the USB version of this sensor, however, with some minor modifications such as allowing the user to set the baudrate and updating the default value (to 9600 instead of 115200) it works perfectly.

This library is available in PyPI and can be installed with pip:

pip install vsr53

from vsr53 import VSR53USB

port = "/dev/ttyUSB0"  # replace with the device port of your gauge
with VSR53USB(port) as gauge:
    print(gauge.get_device_type())
    print(gauge.get_product_name())
    print(gauge.get_measurement_value())
