The VT902ES is a NEMA 4X (IP66) LCD designed to meet Class 2, Div 2 protection. The purge system uses a pressure switch to automatically trigger alarms in case of pressure loss.
Slim and Economical
With its moderate weight and small footprint, the VT902ES series is ideal for
applications where both space and budget are limited.
Durable
The VT902ES monitors is fully enclosed in sealed, NEMA 4x, easy-open,
stainless steel cases. The chassis has no external vents, so nothing can get
under its skin, including weather, dust, dirt, moisture, oil, chemicals or other
harsh contaminants. A hard-anodized cast aluminum heat exchanger and
internal heat management system keep it cool in environments where ambient
temperatures approach 50°C -- without using outside air. With its lightweight yet rugged construction, and either precabled or bulkhead connectors, the VT902ES display is easily mounted on walls, stands, arms or other industrial equipment.
The display is available with optional brackets, that conforms to VESA flat panel
mounting standards.

Z Type Purge System w/ Pressure Switch (Class 2, Div 2 Protection)

This Rapid Exchange® enclosure pressurization that operates on a supply of
compressed instrument air or inert gas. It regulates and monitors pressure within
sealed (protected) enclosure(s), in order to prevent combustible dust
accumulation or remove and prevent flammable gas or vapor accumulations. In
Class II areas, the system maintains a "safe" (1.0") pressure. This process
reduces the hazardous (classified) area rating within the enclosure(s), in
accordance with the NEC - NFPA 70, Article 500, NFPA 496 and ISA 12.4.

OPERATION

In accordance with system instructions, start-up requires air supply to be engaged
and enclosure power to be de-energized. In Class II areas, all dust must be
removed from the enclosure(s). The enclosure protection vent (if used) must be
tested and enclosure(s) must be sealed. The enclosure pressure control regulator is then used to set a safe reading on the enclosure pressure gauge. In Class II areas, power can be energized when safe pressure is stable. Loss of safe pressure in Class I or II areas requires immediate attention, unless power is de-energized. WPS style systems include an explosion proof differential pressure switch with form "C" contacts for audible or visual alarm systems.
