| Standard junctions of sensitive elements |
| UNGROUNDED JUNCTION |
 |
The sensing junction between the leads is totally insulated both electrically and mechanically from the body. Main application is in very hard-working conditions (with vibrations, thermal shocks, chemically aggressive environment, etc.) under which it provides a long working life. |
| GROUNDED JUNCTION |
 |
The sensing junction between the leads is directly welded on the body. This solution allows a good performance under pressure, high humidity and mechanical stress. Also, it is particulary recommended to get a fast response. |
| EXPOSED JUNCTION |
 |
Fast responce is the feature of this junction. It is reccommended for measurement of gas or solid surfaces in non-corrosive environmnts. |
| Thermocouples working ranges | The temperature range depends on the thermocouple type, see below diagram:
