aklab.convert module#

Convertion modules for sensors in use.

aklab.convert.hall_sensor(signal)[source]#

Convert Hall-effect current sensor signal to Amps. An Arduion or Raspberry Pi sensor based on ACS712 or a similar chip.

aklab.convert.ionization_gauge(signal, exponent, log=False)[source]#: Calculate pressure in Tors (Pa) from Bayard-alpert ionization vacuum gauge. A controller usually has two modes: linear and log outputs. In linear mode older converters do not ouotput exponent power, so it must be provided.

aklab.convert.pfeiffer_sg(signal)[source]#

Calculate pressure in Tors (Pa) from Pfeiffer cold cathode Single Gauge. It seems that coefficients are slightly off, tune them for better results.
