Production of Glass ampoules

Pyrometer in the manufacturing process of glass ampoules

Glass ampoules are made of tubing glass and are formed with gas burner flames.

Glass ampoules in medical technology and cosmetic industries serve mainly as containers for the respective products. They are also used as thermal release element in fire detection systems in sprinkler systems and other temperature-controlled release mechanisms. In the manufacturing of these glass ampoules a finished glass raw body is heated and then reshaped to the respetive form.

Pyrometers measure through the flame on the surface of the glass ampoule

These usually full automated processes are proceeding in a horizontal rotating table with several gas burners. The ampoules are heated by the burner to a certain temperature that is crucial for the further processing.

An important part in the process control is to capture the temperatures exactly and quickly. Temperature measurement devices used for this purpose need to be quick, exact and especially unaffected when they are measuring the glass temperature through the gas burner. The particular DIAS pyrometer PYROSPOT DT 40F and DT 44F offer exactly these features. With measurement ranges between 300 °C and 2500 °C, mutable optical proportions and fast acquistion times from 10 ms, the pyrometers measure through the burner flame to the glass surface.

High-End pyrometer DIAS PYROSPOT for very fast production processes in the manufacturing of glass ampoules

For extremely small ampoules or very fast production processes the high-end pyrometer PYROSPOT DPE 10 MF kann be used. This pyrometers measures in ranges between 50 °C and 2500 °C with a acquistion time of only 1.5 ms and can realize measuring fields smaller than 1 mm. The burner flame has no influence on the measurement.

All pyrometers have a standard analoge output available or a digital interface for integration in the process control.

Digital pyometers PYROSPOT Series 4x can measure through flames so that the flame has no influence on the measurement results of the surface temperature of the material.
The pyrometer series PYROSPOT 4x by DIAS Infrared contains special pyrometers for the temperature measurement through flames. In this way the flame has no influence on the measurement results of the surface temperature of the material. The digital pyrometers are available with USB or RS-485 interface.
High-end pyrometer PYROSPOT DPE 10MF made by DIAS Infrared. Very short response time and very small measurement spot sizes.
The high-end pyrometer DIAS PYROSPOT DPE 10MF has a response time of only 1.5 ms and can realize measurement spot sizes of 1 mm. For an easy use it has a display for the temperature and buttons for adjusting parameters.
