Marposs’ Duo Air interface box is designed for easy and economical management of a wide range of air gauges. The Duo Air can be supplied with either one or two analog air-to-electronics converters with adjustable sensitivity and zeroing nozzles for connecting to one or two gauges.
Each converter provides an LVDT output signal for easy association to the Marposs Duo electronic display unit, offering a compact and affordable solution for measurement applications. Duo Air is well suited for measurements with small tolerances, requiring high resolution 0.1 micron.
It is said the Duo Air is accurate, robust and versatile, with the ability to accept air gauges from other manufacturers. Both Marposs and nonMarposs air gauges can be easily and immediately connected to Duo Air, with consideration to the following parameters — air supply pressure of 3 bar ± 0.1; number of air gauge jets; diameter of air gauge jets; and a mid-range gap (the difference between the midtolerance diameter of the part to be measured and the distance between the air gauge jets.
The unit is designed to be easy to configure and easy to use, offering a cost-effective for simple applications. It also features an extremely clear visualization of the measurement status. It is designed for portable use and is suitable for the workshop (IP54 front panel).
In a typical application, the Duo Air offers linearity of < 0.4% of the working range, repeatability of < 0.15 micron, noise of <0.1 micron, resolution of 0.01 micron and a response time of only 200 milliseconds.
Marposs is a global provider of measurement, inspection and test technologies.
