Introduction

caldus is a user-friendly, robust Python package specifically designed to facilitate the conversion between resistance values and temperatures of platinum resistors. It is based on the Callender-Van Dusen equations (thus the name caldus) and the IEC 60751:2022 standard.

Key Features

1. Supports Various Platinum Resistors: The package supports a broad range of platinum resistors including PT100, PT500, PT1000, and more.

2. Easy to Use: Simply input the resistance or the temperature and the corresponding value will be returned.

3. Flexible Integration: Written in Python, caldus can be easily integrated with other Python applications or used for data analysis.

Installation

To install caldus from PyPI, run:

pip install caldus

To install the latest development version from Github, run:

pip install git+https://github.com/gunnstein/caldus.git

Usage

Below is a simple usage example:

import caldus

# Convert resistance to temperature
temp = caldus.resistance2temperature(110)

# Convert temperature to resistance
res = caldus.temperature2resistance(25)

# Alternatively you can use the wrapper functions `r2t` and `t2r` to achieve the same.
res = caldus.r2t(110)
temp = caldus.t2r(25)

print(temp) # output: ~25.68
print(res)  # output: ~109

# All functions can also take array like objects
temps = [0., 12., 21.]
resistances = caldus.t2r(temps)
