Measure BOX

Branca Measure Box is a conditioning cabinet for dimensional metrology and calibration of Johansson gauge blocks according to the Standard ISO DIS 3650, which ensures constant temperature control

Branca Measure Box must be placed in a climate controlled environment under much larger tolerance conditions as indicated below:

To meet the needs of dimensional metrology and the metrology calibration of Johnson parallel gauge blocks, Branca Idealair, specialized in the design and construction of metrological laboratories, offers the this solution to the world of dimensional metrology, in the bench or cabinet models.

Measure Box ensures constant and precise control of the temperature inside the small measuring compartment and within the required tolerance limits of (20 ± 0,1) °C.

The Measure Box structure is suitably insulated and anti-vibration to minimize any vibrations from the floor or bench and the acoustic pressure level of the unit in the surrounding environment is low (<45dB) and in compliance with current regulations.

Thanks to the filtering section located at the bottom of the compartment, the air is sucked by the top, totally eliminating the first convective motions of hot air that release the blocks in the steady temperature and thermal equilibrium phase and re-introduced downwards to ensure a natural outflow after treatment.

The upper limit of Relative Humidity (%) is monitored and actively managed by subtracting latent heat by means of a balanced exchange circuit arranged on the air circuit.

User interface with graphic display with HMI Touch Screen technology on the front side allows immediate reading of the values ​​in real time; moreover it is possible to modify the adjustment parameters, export the graphs in files (.csv) thanks to the continuous acquisition of the flow of records.

In the upper compartment there are the components of the electrical panel with grilled upper panel for the natural escape of the heat dissipated by the components.

In the rear compartment there is the condensate water recovery tray which evaporates again from the flow of air taken from the back of the Measure Box to favor the heat exchange from the inside to the outside and that dispersed in the environment.

We recommend installing the Branca Measure Box at a distance of no less than 20 cm from the wall to allow correct air movement. Through the two transparent front doors with thermal gloves it is possible to access the compartment and operate on the blocks, and / or measuring instruments and in the handling of Johnson parallel blocks. The two front doors are made of polycarbonate material, with handles and can be fully opened at 90° to allow direct access to the interior.

In the bench box version, the Branca Measure Box must be positioned possibly on an anti-vibration table with minimum dimensions of 850 x 650 mm.

An internal / external through hole with a diameter of 50 mm on one of the side walls with a removable cap allows the introduction of additional components or temperature probes necessary during calibration.

On request it is possible to make further through holes.

Measure Box is equipped with electrical and thermal protection devices with integrated alarm diagnostics section on the display.

Optional: interior lighting with fluorescent lamp controlled by a switch on the front panel.

The Branca Measure Box does not need installation interventions.
