Precision Digital Corporation – Loop Powered Meters

Vector CAG - Precision Digital Logo

Precision Digital manufactures a full line of convenient, loop-powered meters which are easy to install and maintain because they get their power directly from the 4-20 mA current loop. Many of these meters feature a 1 V drop to the current loop and are certified as Intrinsically Safe, Nonincendive, and explosion-proof, for use in hazardous areas.

These meters have features that help them to stand out from the competition, such as segmented bar graph representations of the process input, feet & inches level displays, wide operating temperature ranges, and displays that can be easily read in various lighting conditions, from wide angles, and from considerable distances.

PRODUCT DESCRIPTION:

Intrinsically Safe & Nonincendive Loop-Powered Indicators with Advanced Display and Control Features

These intrinsically safe and nonincendive loop-powered 1/8 DIN digital panel 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 dual line display, which is typically used to display the process variable on the 5-digit alphanumeric top display and the units of measure or a tag on the 8-digit 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 available on the PD6607 and PD6608 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. 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.
