Thin film

Thin-film resistors consist of a ceramic substrate with a layer of platinum. These thin-film sensors are about 0.5 mm thick to a maximum of 1 mm. The platinum film is first sputtered or evaporated onto an aluminum oxide substrate. The thin film track on the substrate is then structured using a laser beam to form a serpentine resistance track. The platinum is then protected by a piece of glass approximately 10 to 15 mm thick. The connecting wires are welded on to establish the electrical connection.

Platinum thin-film technology is driven by constant innovation and the high demands of customers. The temperature sensors range from -196°C to +1000°C operating temperatures. The standard value for resistance varies from 100 to 1000 ohms.

The Pt100, Pt500 and Pt1000 generally come in a compact style. All thin films have the same characteristic when it comes to their fast response time. Their low thermal mass has a negligible effect on the environment which is measured. The thin film sensor is interchangeable, stable for long periods of time, has a wide temperature range and it has the advantages of large-scale production.
