Pressure sensors are calibrated on the calibration line.
The sensors are supplied to the calibration system for pressure sensors on customer workpiece carriers via a belt system.
A linear axis picks up the components and places them into a buffer, from where the pressure sensors are picked up by a portal transfer handling system and transferred to the room temperature chain conveyor.
The handling system transports the components to the calibration station. In the calibration station, the process sequence is controlled by test equipment provided by the customer. Sonplas provides high compressed air accuracy and stability for the calibration process.
After the room temperature calibration, the portal handling places the sensors on the chain conveyor in the oven. In different temperature zones there are further calibration station whose process sequence is controlled by the customer’s test equipment.
After the temperature calibration, the pressure sensors are actively recooled during the return conveying; the pressure sensors are then placed in a buffer by the portal handling system, from where they are picked up by a further linear axis and placed back on customer workpiece carriers in the calibration system for pressure sensors.
