Physical Features
The ProtEX-MAX is designed for ease-of-use in safe
and hazardous applications. The ProtEX-MAX is
housed in a rugged NEMA 4X explosion-proof
enclosure, can operate over a wide temperature
range, includes removable screw terminal connectors,
has worldwide approvals for use in hazardous areas,
and features through-glass buttons for easy meter
operation without the need to remove the cover.
All of these features are backed by a 3-year warranty.
Super-Bright LED Display
The ProtEX-MAX features a 4-digit display with
super-bright LEDs, our brightest ever. These allow the
display to be read in any lighting condition, even in
direct sunlight.
SafeTouch Through-Glass Buttons
The ProtEX-MAX is equipped with four sensors that
operate as through-glass buttons so that it can be
programmed and operated without removing the
cover (and exposing the electronics) in a hazardous
area. These buttons can be disabled for security by
selecting the DISABLE setting on the NO-CONTACT
BUTTONS switch located on the back of the
electronics module, inside the enclosure.
Rugged, Heavy-Duty Enclosure
The ProtEX-MAX is housed in a rugged NEMA 4X, 7,
& 9, IP68 die-cast aluminum enclosure, designed to
withstand harsh environments in safe and hazardous
areas over a wide temperature range.
Wide Viewing Angle
Customers can’t always look at the display from
straight on, so the window and display module have
been optimized to provide a wide viewing angle of
approximately ± 40°; nearly twice that of the
competition.
Built-In Mounting Flanges
The ProtEX-MAX is equipped with four slotted flanges
for wall mounting or NPS 1½" to 2½" or DN 40 to 65
mm pipe mounting.
Flexible Mounting & Wiring
The ProtEX-MAX features four ¾" NPT threaded
conduit openings so that wiring can be routed to the
most convenient conduit connection(s). Two ¾" NPT
metal conduit plugs with 12 mm hex key fitting come
installed.
