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'
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'
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'
