Thermocouple Temperature Sensors are used for measuring atmospheric temperature. Thermocouple temperature sensors are the most popular type of industrial temperature sensor. They operate by placing two dissimilar metals together causing voltage to vary according to the temperature.

Thermocouple Thermometer consists of a thermocouple-sensing element producing an electromotive force connected to a device capable of measuring the emf and displaying the result in equivalent temperature units. These are electrical thermometers that use the fact when two different metals are placed in contact a voltage develops between them. Thermocouple thermometers are used to measure the temperature of the various parts of air-cooled engines. A thermocouple thermometers measures temperature at the junction of two fine wires found at the tip of the probe. Thermocouple thermometers display temperatures based upon measurements of very small DC electrical voltages. Thermocouple thermometers are digital electronic instruments into which a thermocouple is plugged. The thermocouple thermometers work on a basic principle of conversion of the thermal potential gradient to electrical potential gradient.

Thermocouple Vacuum Sensor features machined 304 SS body with 1/8 in. NPT connection threads and integral wrench flats for installation. Applications include cryogenic vessels, vacuum jacketed gas delivery manifolds and mechanical vacuum pumps.

Thermocouple wire represents a source of extotic alloys such as nickel-chrome, platinum-rhodium, and iron-constantan. Actually, most alloys used are refractory or noble metals and tend to be quite inert biologically. The insulation jackets are usually high temperature-tolerant polymers such as teflon. Thermocouple wires are often quite stiff and springy and may be very difficult or impossible to solder effectively without special fluxes.

Thermocouples are a type of temperature sensor and used as a means to convert thermal potential difference into electric potential difference. Thermocouples measure the temperature difference between two points. Thermocouples are connected in series with each other to form a thermopile. Thermocouples are temperature sensors suitable for use with any make of instrument designed or programmed for use with the same type of thermocouple. Thermocouples are based on the principle that when two dissimilar metals are joined a predictable voltage is generated that relates to the difference in temperature between the measuring junction and the reference junction.
