The ProtEX+ loop-powered explosion-proof & intrinsically safe meters can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. They can operate down to -40°C and be installed in areas that get as cold as -55°C, however the display will cease functioning. One of the most convenient features is the dual-line display, typically used to display the process variable on the 5-character alphanumeric top display and the units of measure or tag on the 8-character alphanumeric bottom display. Feet and inches models display level in feet and inches on the top display while the 8-digit alphanumeric bottom line may be used to display a tag or custom message. Further enhancing the display on these instruments is a 20-segment bargraph.

The ProtEX+ carries all major approvals including:

• UL Listed as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
• CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
• ATEX and IECEx Certified as Intrinsically Safe / Explosion-Proof

Four CapTouch through-glass buttons are available to operate the instrument without removing the cover. The CapTouch buttons have two modes of operation: Normal and Delayed, and they can be disabled for security via a switch on the display module.

All models come equipped with two open collector outputs and a digital input. There are also models available with two solid-state relays and isolated 4-20 mA analog output options. The open collector outputs are useful for alarm indication. The digital input can be used to acknowledge the relays, to start/stop a timer/stopwatch, and more. The relays can be programmed for alarm indication, on/off control, or pump alternation.
