WET retraction

This an auxiliary node to the measurement node and is used to activate pneumatic finger retraction on measurement heads (Unimar).
The Retraction Node must be connected to a suitably filtered compressed air supply, which it delivers to the heads involved in the measurement cycle selected by the machine logic.

Each Retraction Node can be used to manage the retraction function independently on up to 4 heads. The Retraction Node is manufactured in stainless steel and has been designed to be installed inside the machine working area (wet area). It must be positioned close to the measurement head so that it is possible to use the short connection hoses (typically 3 m), in order to optimize retraction activation/deactivation times.
