Do You Understand All That Loop-Powered Instruments Can Do?
Joe Ryan

To find the right display and control solution for your process, you need to understand all the options you have available, including loop-powered meters. Loop-powered meters can be a great choice for locating a display where there is not easy access to power. Later in this e-mail, you will learn about the NEW Loop Leader+ Large Display Meters, ProtEX+ Explosion-Proof Meters, and VantageView+ Field Mount Meters. These exciting new products provide features we have never had available in loop-powered meters. You can use these loop-powered displays outdoors, in the dark, in environments down to -40°. They can trip alarms, sound horns, and even do pump control. To understand the great value these units can deliver, it is helpful to have a good understanding of what a loop-powered device is and when it makes sense to use one.

If you want to pick the right display for your critical process measurements, you need to understand the core technology behind these loop-powered devices, and when you should look to them for your solution.

Here's a couple of resources you may find helpful if you want to understand the loop-powered displays and controllers available to you:

The Most Comprehensive Line of Loop-Powered Indicators on the Market!
Loop-Powered 1/8 DIN Panel Meters
Loop Leader Loop-Powered Panel Meters
Three New Products Lines Launching July 2022
Loop Leader+ ProtEX+, and Vantageview+ Loop-Powered Meters

In 2018, with the launch of the Loop Leader PD6600 1/8 DIN digital panel meters, Precision Digital radically improved and expanded the features and functionality expected from loop-powered indicators.

In 2022, Precision Digital is broadening its line of loop-powered indicators to include three new product lines that share all the features, functionality, and programming of the PD6600 digital panel meters:

  • PD6900 ProtEX+ Explosion-Proof Meters
  • PD6900 VantageView+ General-Purpose Field Meters
  • PD4 Loop Leader+ Large Display Field Mount Loop-Powered Meters

We now have the most complete line of loop-powered meters on the market!

One of the most important improvements to the new ProtEX+ and VantageView+ meters is the replacement of the IR through-window buttons with the more reliable capacitive touch through-glass buttons. This is the same technology used in modern smart phones.

Precision Digital’s Loop Leader and Loop Leader+ loop-powered meters when equipped with the two solid-state relays option make great pump controllers. The relays can control two pumps and even be set up to alternate the pumps based either on cycle or time. In addition, the two open collectors that are a standard feature can be used to trigger high and low alarms.

Common Features of All Product Lines:
  • Same Programming Menu, Software, and Functionality for All Products
  • Process Meters, F&I Level Meters, and Rate/Totalizers
  • Dual-line Display with Two-Color Backlight for Alarm Indication
  • 20-Segment Bargraph
  • (2) Open Collector Outputs Standard
  • (2) Loop-Powered Solid-State Relays and 4-20 mA Output Options
  • Free PC-Based MeterView XL USB Programming Software
  • F&I Models Display Level in Feet & Inches
  • Rate/Totalizers Display Rate and Total Simultaneously
PD6600 Loop Leader Features:
  • 1/8 DIN Panel Meters with a NEMA 4X, IP65 Front
  • Intrinsically Safe and Nonincendive Models Available
PD4 Loop Leader+ Features:
  • Wall Mounted NEMA 4X, IP65 Large Display Meters
  • The largest Digits on a Loop-Powered Indicator on the Market
  • 2.8" (71 mm) Top Display and 1.5" (39 mm) Bottom Display
  • Intrinsically Safe Models Available
PD6900 ProtEX+ Features:
  • Explosion-Proof and Intrinsically Safe
  • Housed in Explosion-Proof NEMA 4X, IP68, Die-Cast Aluminum or Stainless Steel Enclosure
  • CapTouch Through-Glass Buttons Programming
PD6900 VantageView+ Features:
  • Field Mounted Indicators for Safe Areas
  • Housed in a Plastic NEMA 4X, IP66 Enclosure
  • CapTouch Through-Window Buttons Programming

These new products will be formally introduced in early July. If you would like special advance notification of this product launch, please click below.


Pump Control with the Loop LeaderPrecision Digital features easy-to-use, and feature-packed devices that can satisfy a wide variety of pump control applications. They are available in 1/8 DIN panel mount, explosion-proof, and NEMA 4X wall mount configurations.

The PD6000 Pump Controller and PD8-6000 Explosion-Proof Pump Controller are loaded with features like an informative dual-line 6-digit display, a 24 VDC power supply to power any level transmitter, and user-friendly programming without the need for a PLC. It can alternate up to 8 pumps to control the level of sumps, tanks, or wells.

The PD765 Pump Controller and PD8-765 Explosion-Proof Pump Controller have features including a huge 1.2 inch (30.5 mm) display that can be seen from afar, user-friendly programming, and a 24 VDC power supply to power the transmitter. It can alternate up to 2 pumps to control the level of sumps, tanks, or wells.

The PD6604 Loop-Powered Panel Meter when equipped with the two solid-state relays option makes a great pump controller. The relays can control two pumps and even be set up to alternate the pumps based either on cycle or time. In addition, the two open collectors that are a standard feature can be used to trigger high and low alarms.

The ConsoliDator+ Multivariable Controller can be used for a wide variety of pump control applications. Whether the system has two, three, or even five pumps, the ConsoliDator+ will provide the alternation scheme needed to ensure the pumps last as long as possible. Pumps can be alternated based on level readings and/or pump run time for maximum pump efficiency. The ConsoliDator+ can also help with preventative pump maintenance by alerting an operator when a pump has exceeded a user-defined threshold of total pump runtime. The ConsoliDator+ can also perform the pump alternation sequence with a single float switch input in case of primary sensor failure. See example of the ConsoliDator+ controlling multiple sumps!

Fundamentals of PID ControllersAlthough PID controllers are a very common type of process controller they have many unique features that make using, selling, or specifying them different from other devices that have simple on/off control such as panel meters and process displays. Precision Digital recently conducted a webinar – Fundamentals of PID Controllers, that answers this very question and more. The webinar was designed for the engineer, operator, or salesperson who is familiar with panel meters and other basic process meters and is looking to learn more about what makes PID controllers different. Build your list of the “Need to Know” questions for when you want to buy, sell, or specify the right PID controller.

Featured Application
Level Indication & Pump Control with the ProVu Series

Level measurement and pump control go hand-in-hand, whether it is making sure that your tanks stay full or that they don’t overflow. Traditionally, however, these two processes required separate devices, a pump controller, and a level indicator. Precision Digital’s ProVu Series combines both level indication and pump control into one device. Not only that, they also offer advanced multi-pump alternation control functionality which can help maximize the life-span of your pumps.

Loop powered indicators have until now lacked advanced control features. The Loop Leader Series radically improves and expands the functionality expected from a loop powered indicator without sacrificing cost-efficiency, ease-of-use, or voltage drop. These loopJoe Ryan, VP of Sales & Marketing at Precision Digital, introduces the New PD500 SuperNova Series and shows all the standard features and powerful options this modern line of process and temperature controllers has to offer. Reverse polarity LCD screen, easy auto/manual mode switching, 4-20 mA remote SV input, alarm relays, 4-20 mA retransmit, and standard USB port were just a handful of the great features discussed in this webinar. Joe also reviewed all the important features of the New SuperNova controllers, compared them to the old Nova series previously offered, and showed the SuperNova TCS programming software.
