Current (4-20 mA) Field Mounted Indicators

The Loop Leader+ loop-powered large display meters
can be installed virtually anywhere to provide convenient
and informative display of any 4-20 mA signal. One of
the most convenient features of these instruments is their
large, dual line display. The 2.8" 5-digit top display is used
to display the process variable while the 1.5" 8-character
alphanumeric bottom display can be used to display the
units of measure or a tag. 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 that also includes a numeric value of
the percentage the bargraph represents.
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.

The PD4 is available in two configurations: Display only
and with two solid-state relays and 4-20 mA analog output.
All models come equipped with two open collector outputs
and remote contacts. The open collector outputs are
useful for alarm indication. The remote contacts can be
used to remotely operate the four programming buttons, 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.

Finally, there are intrinsically safe versions of these
instruments that can be installed in hazardous areas.

The Loop Leader+ loop-powered large display flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. One of the most convenient features of these instruments is their large, dual-line display which is typically used to display flow rate on the 2.8" 5-character alphanumeric top display and flow total, flow grand total, or a tag on the 1.5" 8-character alphanumeric bottom display. Both display lines use 14-segment, alphanumeric characters that provide much clearer indication of tags, units, or alarm messages than 7-segment characters do.

Further enhancing the display on these instruments is a 20-segment bargraph that also includes a numeric value of the percentage the bargraph represents. 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.

The PD4 is available in two configurations: Display only and with two solid-state relays and 4-20 mA analog output. All models come equipped with two open collector outputs and remote contacts. The open collector outputs are useful for alarm indication or pulse output. The remote contacts can be used to remotely operate the four programming buttons, to 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.

Finally, the PD4-6628 is an intrinsically safe version that can be installed in hazardous areas.

Go with the Helios PD2-6001 when you prefer to read level in feet and inches instead of the more common decimal format. This unique display will read up to 99 feet, 11 & 15/16s inches on the upper line. The lower line can display a tag or volume, even from non-linear tanks such as round horizontal ones. The PD2-6001 makes a great outdoor tank side indicator because its display is bright enough to read in direct sunlight and it will operate from -40 to 150°F. The PD2-6001 can also be equipped with a 4-20 mA output as well as four relays that can be used for alarming or controlling applications, including pump alternation control.

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.
