Description

The APEX 2003.SI control unit controls and monitors the purging and operating phases in Ex p protected analysis systems with integrated containment.

Additional function:
By connecting additional pressure sensors, the pressure inside the enclosure is regulated by means of a proportional valve to a higher level than that of the measuring gas. The flow of purge gas during the purging phase is at most 4100 standard litres / h while the pressure inside the enclosure is 50 mbar. The control unit features two freely programmable relays and one non-floating enabling contact.
