G31_thermometry

A Python package useful to convert thermometer readout voltage to temperature for the G31 Cosmology Group at La Sapienza University of Rome.

Supported thermometers

• Lakeshore DT670 D6068043

How to add new thermometers

For now it is possible to add only Lakeshore thermometer calibration files, just go to Lakeshore website, insert the serial number of a thermometer and download the zip file. Extract the zip file and copy/paste the extracted directory as a subfolder of thermometer model directory.

How to install

From ipython:

pip install G31-thermometry

Example

In this example we define a DT670 thermometer with serial number D6068043 and plot its calibration curve.

import G31_thermometry as G31t

DT670 = G31t.Thermometer(model='DT670', serial_no='D6068043')
DT670.plotCalibrationCurve()

The calibration curve is shown below.

With the following code instead we want to convert measured voltages into temperatures.

import G31_thermometry as G31t
import numpy as np

DT670 = G31t.Thermometer(model='DT670', serial_no='D6068043')

voltage = np.array([0.5  , 0.625, 0.75 , 0.875, 1.   ])
DT670.temperature()

Output (in kelvin):

np.array([324.73716731, 270.61138912, 214.82655846, 156.39544034,
        92.6566496 ])
