Thermocouple Temperature Sensor with Seebeck Voltage Measurement and Dissimilar Metals Junction

The primary function of a thermocouple is to measure temperature.
It does this by generating a small electrical voltage (known as the Seebeck voltage or thermoelectric EMF) that is directly proportional to the temperature difference between its two ends. This voltage is then measured and converted into a temperature reading by a connected instrument.

A thermocouple consists of two wires made of dissimilar metals joined together at one end (called the measuring junction or hot junction). The other ends are connected to a measuring instrument (forming the reference junction or cold junction).
1. When the measuring junction is exposed to heat, a voltage is generated due to the Seebeck effect.
2. This millivolt-level voltage is measured at the reference junction.
3. Since the voltage depends on the difference in temperature between the two junctions, the temperature of the reference junction must be known (usually through automatic compensation in the measuring device) to accurately determine the temperature at the measuring junction.

Founded in January 2003,Jinan HYDEB Thermal Tech Co., Ltd. is located in Jinan High-tech Development Zone.

Hydeb mainly produces molten aluminum refining and degassing units, molten aluminum transfer ladles and holding crucible furnaces, which are sold to well-known corporations in the industry at home and abroad, meeting their high requirements for product safety and advancement.

Focusing on the aluminum casting industry, the Company takes “Technology, Quality and Service” as its base of enterprise, aimed at meeting all the needs of customers. Being “Safe, Practical, Reliable, Efficient and nice-looking”, its products are well unanimous recognized by the customers, with its brand “HYDEB” gaining high popularity in the industry.

To meet the increasingly high requirements for aluminum casting products, HYDEB gives full play to its technological superiority and engages industry experts as technical directors, developing products urgently needed in the market such as the counter (low) pressure casting holding crucible furnaces and molten aluminum refining and degassing units. It has also established long-term and friendly partnerships with a number of large-scale Chinese integrated equipment suppliers, sustaining its annual supply level of more than 80 sets.

“Taking the lead and creating a brand name in the industry”. We will continue to advance on the path of professional development and continually improve our products and services to further meet our customers’ development needs and support their creation of greater values.
