The main facility in the production of sensors is a continuous melting furnace. With this furnace several sensor components are sintered or melted gas-tight dependent on the working step. The temperature curve in the continuous furnace is adjusted and held very precisely to the desired temperatures through special regulatory mechanisms.

Due to the functional principle of the sensor, several components are applied using thick film technology. This is done by using high-precision screen printers.

To meet the specified resistor tolerances of the sensor heater, the heating resistor is recorded with a high-precision 4-wire resistance measurement in a trim laser which leads to a corresponding correction.

To ensure durable and long-term stable material connections between various materials, special welding techniques are used in the sensor production. In this section we rely on longtime experiences in the field of gap welding technology.

To ensure permanent batch traceability, each sensor is provided with an engraving after the final assembly, which includes year and week of production and production-specific data. In addition to this production information, the measuring range of the sensor is engraved in the form of a coded letter.

To prevent that parts reach our customers which do not meet the specification, despite extensive, production associated inspections, all sensors are subjected to a 100% final inspection in our last production step. All relevant sensor data are recorded computer-based, calculated and then stored manufacturing batch-related.

Our products are regularly monitored in a long-term function control to ensure consistently high quality. Thereby the functionality of the sensors is checked under practical conditions over a defined period of time.
