The ProtEX+ loop-powered explosion-proof & intrinsically safe flow rate/totalizer 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 flow rate on the 5-character alphanumeric top display and flow total, flow grand total, or tag on the 8-character alphanumeric bottom display.

The top display uses 12-segment, and the bottom display uses 14-segment alphanumeric characters for clear indication of tags, units, or alarm messages. 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 or pulse output. The digital input can be used to remotely reset the total, to start/stop a timer/stopwatch, and more. The relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.

Free, PC-based, MeterView XL software that connects to the meter via a micro USB cable is available for programming and setup of the meters. This software greatly simplifies the programming process and also allows the user to save configuration files for later use.

The meter will also be powered by the USB connection so no additional power is needed during programming.
