A JavaScript module for thermocouple voltage to temperature conversions. Based on the Python script I wrote of the same function.
Uses polynomial functions with NIST thermocouple tables and coefficients.
- Supports thermocouples of types B, E, J, K, N, R, S, T
- All voltage is measured in millivolts (mV)
- All temperature measurements are in degrees Celcius
No warranty given or implied whatsoever with this tool. Use at your own risk.
Create sample.js:
// Convert type K 4 mv to degc
var Thermocouple = require('thermocouple-converter');
var result = Thermocouple.convert(4.0, { type: 'k', input: 'mv' });
console.log(result);pnpm was used here but instructions here are given for the more common npm package manager.
Install package with npm (remove --production to install devDependencies):
npm install thermocouple-converter --production
Run command to give result of 97.64 degrees:
$ node sample.js
97.64306383175676
Thermocouple.convert(INPUT_VAL, { type: TYPE, input: TC_TYPE });Parameters:
INPUT_VAL- input value to be convertedTYPE- single alpha character denoting thermocouple typeTC_TYPE-mvordegcdesignatingINPUT_VAL's units. Determines conversion direction.
If no parameters are supplied, k (Type K) and mv is used as default. This results in Type K millivolts conversion to degrees Celcius.
Convert 4.0 millivolts from type K thermocouple to temperature.
var result = Thermocouple.convert(4.0, { type: 'k', input: 'mv' });Convert 100.0 degrees C to type K thermocouple millivolts.
var result = Thermocouple.convert(100.0, { type: 'k', input: 'degc' });Load script with <script> tag:
<script src="Thermocouple.js"></script>Execute custom conversion as normal JS, for example, insert this inside your <body>:
<div id="result"></div>
<script>
var result = Thermocouple.convert(4.0, { type: 'k', input: 'mv' });
document.querySelector('#result').innerHTML = result;
