The ProtEX+ loop-powered explosion-proof & intrinsically safe flow rate/totalizers 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. 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.
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 relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.
