Pneumatic Measuring Pneumatic Converter

The pneumatic measuring can be used in many areas of industrial production. The method and technique of pneumatic measurement is particularly characterized by the very high accuracy of 1.0 micron and very good stable Wiederholfähigkeit of 0.1 microns in a very short time. The Unaffected by the environment (dirt / temperature) makes it unnecessary to clean the parts to be measured to achieve with this method, a good reproducibility of the results.


Pneumatic measuring The pneumatic measuring is a non-contact measurement that protects the parts to be measured. Typical applications are measurements of diameter, length measurement between axes, measuring cone, eccentricity, pairing measurement etc are typical applications of this type of measurement.

The functional principle of the pneumatic PFL - converter is based on the balance of pressure in flowing media by Bernoulli in which between the two chambers are separated by a membrane, the pressure is compared.


Said measuring is a measuring pin or measuring ring, with a digital display or a mechanical display clock or an electronic switch. In this case, the measured value is transmitted as a pneumatic deflection of the diaphragm in an equivalent electronic value.


This result can be with our dial manually or with electronic display components such as gauges of the partner company Pretec further processed in programmable gauges and measuring up to our PC-based measurement software bridge that can be used on all Windows PC used. The range of the standard PFL - converter is + / - 40μm. The special versions have a range of + /-10 microns and + / -80 microns
