[15] Description of Product
The IPS-4-DB is a dual-bench process spectrophotometer that is housed in a two part IP 65 rated stainless
steel enclosure, and has a certified purge control system, an Expo MiniPurge Model 07 1XLC/ss/PO or Model
07 1XLC/SS/ET/PO, SIRA 01 ATEX 1295X on the part of the enclosure that houses the electronics.
The sample system is housed in the unpurged part of the enclosure and contains an Ex d heater. The power
is supplied into the Ex px enclosure from a component approved Ex d enclosure that contains rel ays to cut all
of the circuits going into the purged enclosure via ATEX certified bushings. The relays for the purged portion
of the enclosure are controlled by an Ex d pressure switch that is operated by the purge controller. The
pressure relief valve on the pressurized enclosure is part of the certified purge control system and is set at 1
000 Pa. An optional Ex d certified pressure transmitter (Rosemount) is available for monitoring the sample
system pressure and is simply connected to the IPS-4 through an existing entry on the disconnect enclosure.
