Thermocouple Voltage Conversion

This library converts between voltage and temperature and vice versa for the 8 most common thermocouple types.

View a simple demo of it in action.

import Thermocouple from 'thermocouple';

let tempC = Thermocouple.millivoltsToTemp('e', 68.787);
let mVolts = Thermocouple.tempToMillivolts('k', 983.45);

millivoltsToTemp

static millivoltsToTemp(tcType: string, mVolts: number): number

Argument | Type | Description -------- | ------ | ------------- tcType | string | Thermocouple type. Valid types: 'b'|'e'|'j'|'k'|'n'|'r'|'s'|'t' mVolts | number | Voltage value in millivolts. Valid range depends on thermocouple type returns | number | Temperature in °C. Returns NaN if input is outside thermocouple range

tempToMillivolts

static tempToMillivolts(tcType: string, temp: number): number

Argument | Type | Description -------- | ------ | ------------- tcType | string | Thermocouple type. Valid types: 'b'|'e'|'j'|'k'|'n'|'r'|'s'|'t' temp | number | Temperature value in °C. valid range depends on thermocouple type returns | number | Voltage in millivolts. Returns NaN if input is outside thermocouple range

Thermocouple specific classes

In addition, there are thermocouple specific classes which have similar methods plus access to the valid input ranges.

import { TypeKThermocouple } from 'thermocouple';

let typeK = new TypeKThermocouple();

let tempC = typeK.millivoltsToTemp(28.484);   // 684.62...
let mVolts = typeK.tempToMillivolts(983.45);  // 40.629...

let [minV, maxV] = typeK.voltageRange;        // [-6.458, 54.886]
let [minT, maxT] = typeK.tempRange;           // [-270, 1372]
let name = typek.name                         // 'k'
